1.0 BACKGROUND The U.S. National Science Foundation (NSF) announced the award of the Integrated Ocean Drilling Program (IODP) contract for the riserless drillship to the Joint Alliance (JA) of Joint Oceanographic Institutions, Inc. (JOI), Texas A&M University (TAMU, Science Operator) and Lamont Doherty Earth Observatory (LDEO, logging subcontractor) as the Implementing Organization on September 30, 2003. The proposed plan for the IODP is to carry out scientific coring operations in the oceans of the world using three coring platforms: • A riser drillship supported by Japan • A riserless drillship supported by the U.S. • Alternate platforms of opportunity supported by the European community

The riserless drillship selected by the JA could be in a shipyard for upgrades by late spring to early summer in 2005 (Attachment I). It is estimated that equipment will be ordered six months before the shipyard date. The goal of this Market Survey is to obtain information on equipment for the riserless drillship supported by the U.S. We request that the Market Survey data be returned to Texas A&M Research Foundation (TAMRF) by January 16, 2004 and include the cost summary, equipment specifications, and detailed technical responses to the requests for information and recommendations. The address for TAMRF is: 1000 Discovery Dr., College Station, TX 77845.

The following attachments are provided to assist you in creating the market survey response: Attachment I defines the potential timelines associated with the drilling contractor Request for Proposal (RFP). Attachment II identifies potential drilling contractors and candidate drillships that may be available for IODP operations in response to the RFP. Attachment III (Overview of Scientific Coring) outlines the operational practices of the Ocean Drilling Program for scientific coring. Attachment IV is a cost summary to be returned by the vendor in response to the Market Survey. Attachment V describes the derrick and drilling equipment used on the JOIDES Resolution for scientific ocean drilling/coring. This information is provided as background for conversion requirements for a vessel. Attachment VI describes trip speeds when pulling pipe with equipment used on the JOIDES Resolution. This information is provided as background for conversion requirements for a vessel.

2.0 PURPOSE OF MARKET SURVEY This market survey is being undertaken by TAMU on behalf of the Joint Alliance for the riserless vessel for IODP scientific coring. TAMU is interested in obtaining technical information, budgetary pricing, and estimated procurement schedules on a derrick and related drilling equipment to: • improve our understanding of the current state of the art in this equipment, and • determine the funding level required to convert a pre- or post-1995 drillship (Attachment II) to a U.S. riserless coring vessel for use by IODP.

0_Market Surv DE vendors15.doc 5 of 27 1/14/04 Drilling Equipment Market Survey

3.0 INFORMATION THE VENDOR NEEDS TO PROVIDE TAMU TAMU requests information for two possible upgrade scenarios as well as information on an inspection and servicing arrangement for the drilling equipment. TAMU is using the ODP drillship, the JOIDES Resolution, as the technical and operating reference for this market survey to ensure that all vendors understand the unique nature of the drilling equipment required for continuous coring for scientific investigations (see Attachment III). Current or past operational procedures provided in this document should not be construed as the template for future operations and are provided for information only. Responders are encouraged to be innovative in their presentation of future operational procedures. An overview of ODP engineering tools and hardware can be viewed at: http://www- odp.tamu.edu/publications/tnotes/tn31/tn31.htm .

3.1. REQUESTED INFORMATION/RECOMMENDATIONS Although we recognize that these are only preliminary estimates, we request that the vendors pricing be accurate to within + 10% (ten percent).

We also request that you provide your cost and lead-time estimates for delivery in the format shown in Attachment IV (Cost Summary).

Please note, specific requests for recommendations from you are marked with a red box. If there is more than one recommendation requested, they are also marked with lower case Roman numeral numbers. Several of these items are also listed on Attachment IV, Cost Summary. In addition, requests for information/ recommendations are listed in their entirety at the end of this document (Section 6.0). It is important you respond to all such requests in your vendor response.

3.2. SCOPE OF WORK The primary function of the IODP vessel is to support coring, drilling, logging, and testing for scientific ocean research worldwide. The maximum hole depth is estimated to be 4000 meters below seafloor (mbsf). Holes may be loaded with mud, usually for logging, but heavy mud (up to 12.5 ppg) will not be used except as a kill fluid. The maximum water depth is 7000 m.

By definition, the vendor would consider in his market survey documentation response the configuration and limitations of both the pre- and post-1995 drillships listed in Attachment II. Please provide, as appropriate to your company, the following information: 1. the estimated costs and time line to replace (Scenario I) or service and modify (Scenario II) the derrick and drilling equipment, as required, on a(any) post-1995 or pre-1995 candidate drillship(s); 2. the operational capacities and specifications for vendor's proposed drill floor and derrick equipment to handle any of the three drill pipe size options described in Table 2; 3. estimated procurement timelines to service, upgrade, or replace the equipment; 4. estimated costs to inspect and service equipment items 1-7 listed under "Inspection and Servicing of Drilling Equipment," 5. the availability of real time diagnostic systems to monitor rig drilling equipment and support the drill crew in fault finding and repair; 6. impact of each of the three drill string size options on ship conversion and on trip time for the three specified water depths (Table 3 in "Trip Speed" section and Attachment VI); 7. estimated cost to modify the drill floor, derrick, and substructure to handle and run a top hole drilling package as well as equipment descriptions, recommendations, and specifications of the handling equipment for the THDP, and; 8. possible solutions to enable the derrick to handle drill pipe in triples and pass under the Bridge of Americas (AKA Panama Canal Bridge) in Panama. The maximum height at transit draft to clear the Panama Canal Bridge is 62 m.

Note: Transiting the canal is a desirable, but nonessential element of the IODP riserless vessel design.

 We request that you provide your summary cost and lead-time estimates for delivery in the format shown in Attachment IV (Cost Summary).

4.0 DRILLING/CORING EQUIPMENT FOR VESSEL CONVERSION TAMU requests information for three sections: (1) two upgrade scenarios (Subsection 4.1), (2) replace the drilling equipment for the two upgrade scenarios (Subsection 4.2), and (3) the inspection and servicing of drilling equipment (Subsection 4.3). TAMU utilized the ODP drillship as a technical and operating reference to ensure that all Drilling Equipment Vendors understand the unique nature of the drilling equipment required for continuous coring for scientific investigations (Attachments III and V). Attachment V describes equipment based on the systems used by ODP for scientific coring. The derrick equipment is unique, as it must accommodate a wireline retrievable core barrel. The other drilling equipment is typical for an early generation drillship.

4.1. TWO UPGRADE SCENARIOS We request that you define the optimum means, estimated time to complete, and estimated cost to accomplish one of the following two upgrade scenarios to both the pre- or post-1995 drillships listed in Attachment II.

4.1.1. Scenario I Install a 1.6 million-lb derrick and substructure on any operating pre-1995 drillship. In addition, replace the existing drill floor and derrick drilling equipment on the drillship.  Specific work to be discussed and costed: • A 1.6 million-lb derrick and substructure with drill string compensation (DSC) that can handle 90 ft triples and has a minimum number of umbilicals hanging in the derrick. • Recommend optimal procedures compatible with the new derrick and substructure for safe and efficient pipe handling (i.e., making up and laying down pipe and BHA components) to minimize the time spent tripping and preparing for transit. • An overhead crane under the substructure to move 10 MT heavy lifts from the spotting area to under the derrick in the moonpool area for eventual deployment through the moonpool.

4.1.2. Scenario II Fully inspect, service, and modify the existing derrick and substructure on a pre-1995 drillship for 10-15 years of additional continuous service. In addition, replace the existing drill floor and derrick drilling equipment on the drillship with new drilling equipment suitable for continuous scientific coring and compatible with the existing (assumed to be a 1.0 million-lb) derrick.  Specific work to be discussed and costed: • Modify the existing derrick to accomplish the following: ♦ Provide adequate clearance for the traveling equipment for coring operations and handle 90-ft triples. ♦ Limit the number of independent umbilicals hanging in the derrick. • Recommend optimal procedures compatible with the derrick and substructure for safe and efficient pipe handling (i.e., making up and laying down pipe and BHA components) to minimize the time spent tripping and preparing for transit. • Please comment on the feasibility of increasing the static strength of the derrick and substructure to 1.6 million pounds. • An overhead bridge crane under the substructure to move 10 MT heavy lifts from the spotting area to under the derrick in the moonpool area for eventual deployment through the moonpool.

4.2. REPLACE DRILLING EQUIPMENT FOR SCENARIOS I AND II Both Scenario I and II require that the necessary drilling equipment (see Attachment V for more detailed descriptions) on the drill floor and in the derrick, as listed below, be replaced with new traveling and drilling equipment. New equipment is required to accommodate retrieval of the 9.5-m long core barrel used for continuous scientific coring (i.e., the equipment must have space for the core barrel, sinker bars, and overshot to be retrieved through it after breaking the drill pipe connection on the rig floor). The core barrel is retrieved with the coring line winch.  Please provide documentation and the cost (Attachment IV) for the following equipment (listed in Subsections 4.2.1 through 4.2.4) compatible with the strength of the proposed derrick (i.e., the 1.6 million-lb and 1.0 million-lb static derricks described above).

4.2.1. Derrick Traveling Equipment 4.2.1.1. Crown Block Crown block is split to allow the coring wireline to pass through.

4.2.1.2. Traveling Block Traveling block is split to allow the coring wireline to pass through.

4.2.1.3. Drill String Compensator The Drill String Compensator (DSC), which includes a Passive Heave Compensator (PHC) and an Active Heave Compensator (AHC), will be used while coring in water depths from 100 m to 7000 m (drill string lengths to 11,000 m).

The DSC system needs • To control the drill string motion to within 4 in. (+/-2 in.) of deviation relative to the seafloor (within three vessel heave periods). • To remove greater than 95% of the ship’s heave from the absolute motion of the drill string. • To operate with vessel heave of 25 ft, roll of +/-4°, pitch of +/-5° and heave velocity not exceeding 5- ft/sec (assume minimum heave periods of 6 sec). • To operate with a hanging load of 1,000,000 lb of drill string and BHA. • To have load rating (1,000,000 lbf) that does not include any derrick traveling equipment above the top joint of the drill string such as the swivel, traveling block, top drive, or any other hardware in the derrick that will contribute to increased hook load indication. • A configuration in the derrick that will accommodate the top drive handling triple stands of pipe. • To operate in an ambient temperature ranges from –40°C to 50°C. • To include hydraulic lines in the derrick instead of hoses, wherever possible. • To have a minimum stroke of 25 ft.

The following configurations will be considered for the DSC: • In-line or piggyback, where the Active Heave Cylinders are retrofitted to an existing derrick with PHC cylinders. Design emphasis is to be placed on reducing the number of hydraulic and electric service loops required in the derrick. • Crown mounted, where the PHC cylinders and AHC cylinders are packaged into the crown. • Hydraulic derrick, where the DSC is integrated into the derrick design, thereby minimizing derrick traveling equipment, derrick mass, and wind load. • Compensated drawworks, where the drawworks has increased horsepower to act as the DSC for the required 5-ft/sec vessel heave velocity.

The Active Heave Compensator will be used for the following tasks during scientific coring operations: • Piston Coring; the drill string and the coring line must be compensated at the same rate so no relative motion exists between the drill sting and core line • Landing of wellheads. • Drill bit reentry. • Running casing. • Cementing operations. • Bare rock spud on hard rock. • Drilling operations with a hydraulic hammer to install casing in hard rock (e.g., basalt). • Completion operations on a cased hole.

To be able to accomplish the above tasks, the driller needs to adjust the AHC to operate with a range of landing and coring weights for the BHA, equipment modules, casing strings, or downhole tools by making adjustments to the AHC output (pressure of the hydraulic power unit and the setting of the pressure relief valve if the unit is hydraulic) to allow the driller to adjust the maximum force from the AHC when reentering the guide cone or landing equipment and for coring operations.

Design parameters for the DSC should take into consideration the following components of friction force on the system:

0_Market Surv DE vendors15.doc 8 of 27 1/14/04 Drilling Equipment Market Survey

• Active compensator hydraulic seals – 5,000 lb • Passive compensator hydraulic seals – 20,000 lb • Guide Horn Friction – 6,000 lb (maximum); this is a device to reduce bending stress of the drill string, installed beneath the rotary table, through the moonpool to the ship’s keel.

The hydraulic system should have the capability to bring a spare motor/pump on-line, and accordingly remove a motor/pump from service for maintenance without interruption to DSC service.

In the event of a mechanical or electronic system failure with the AHC controls, the DSC should revert to a PHC system. The DSC driller’s controls should have a safety interlock to shut down erratic oscillations in the DSC.

The operator’s panel shall be easily accessible to the driller with simplicity of operation, have readable gauges in bright sunlight, and operator friendly in cold weather. The control panel shall be user friendly related to shutdown and start-up of the AHC and PHC when connections are made.

4.2.1.4. Hook Requires a hole for the coring wireline.

4.2.1.5. Swivel, Wireline BOP, and Oilsaver Requires a hole for the coring wireline.

4.2.1.6. Top Drive Requires a hole for the coring wireline.

4.2.2. Unique Coring Equipment Required by Scientific Operations 4.2.2.1. Coring Winch and Wireline A split crown and traveling block permit a high-speed coring wireline to be run through the drill string. An inline drill string compensator, the hook, top drive, and swivel will need 5-in. openings on the centerline to accommodate core barrel operations. The drill floor will need to be equipped with a double-drum high- speed drawworks for core barrel retrieval by coring line. This system allows core barrels and tools to be run and retrieved by wireline at rates of ~200 m/min, which permits rapid continuous coring. The control cabin needs to have a clear view of the drill floor, the derrick, and the driller. The core winch controls could be integrated into the driller's doghouse.

The coring wireline winch and wireline needs to be sized for the following core barrel weights based upon three different drill string configurations (Table 1). The core recovery speed needs to be a minimum of 200- 250 m/min (650-820 ft/min) with a depth capacity of 11,000 m (36,000 ft). Each drill string can accommodate a different diameter 9.5-m length core barrel as shown in Table 1.

Table 1. Drill String Options vs. Core Diameters Drill String Recommended Core Core Drill String Sizes (in.) Clearance ID Core Barrel OD Diameter OD Weight (in.) (in.) (in.) (lb) 5 x 5-1/2 (existing) 4.125 3.5 2.312 135 5-7/8 4.875 4.2 3.5 327 6-5/8 5.875 5.3 4.4 428

 Recommendations would be appreciated on the wireline size and an assessment of core barrel recovery times for the above coring winch for the three drill string configurations shown in Table 2: • the three water depths and total depth scenarios shown in Table 3 (Subsection 4.4 below) and • a core barrel pullout force of 12,000 lb is required on a 30,000-ft wireline with a 1500-lb wireline load (sinker bars and overshot).

4.2.2.2. Heave Compensator for Coring Line The heave compensated coring winch should control the coring line motion to within 4 in. (+/-2 in.) of deviation relative to the seafloor (within three vessel heave periods). The requirement is to remove greater than 95% of the ship’s heave from the absolute motion of the coring line. The heave compensator needs to operate with vessel heave of 25 ft, vessel roll of +/-4°, vessel pitch of +/-5° and with vessel heave velocity not exceeding 5 ft/sec. Minimum heave periods of 6 sec are to be assumed. In the event of a mechanical or electronic system failure of the heave compensator, the winch shall be able to operate as a standard core winch. The coring line winch control panel shall be easily accessible with simplicity of operation and with the capability to read the gauges in bright sunlight, and operator friendly in cold weather. The control panel shall be user friendly related to shutdown and start-up of the drill string compensator when pipe connections are made. The relative motion between the actively compensated drill string and the actively compensated coring wire line should be minimized. The heave compensated coring wireline is required for piston coring, for retrieving core barrels and for landing special downhole in-situ sampling tools in the drill string.

4.2.2.3. Iron Roughneck Capable of handling 5-in. to 9 1/2-in. diameter range drill pipe and drill collars. Capable of making up casing (10-3/4 in., 13-3/8 in., 16 in., and 20 in.).

4.2.2.4. Core Barrel Stabbing Guide Please refer to Attachment III for background information on the core handling routine used by ODP. Because of the scientific coring operations, all derrick traveling equipment and the crown were designed to allow access into the drill string by a wireline winch. Core barrels were free-fall deployed by breaking the pipe at the rig floor and inserting the barrel into the drill string. A coring-wireline-packoff/air-wiper system above the top drive allows the hole to be circulated (at up to 500 psi) and allows the pipe to be rotated slowly with the wireline in the pipe during inner core barrel deployment and retrieval. If circulating pressures exceed 500 psi, the sinker bar system must be removed prior to the connection. A man must go up in a riding belt to the traveling block (above the wireline BOP on the top drive) to insert the wireline/sinker-bar/overshot assembly into the pipe. We would like to change this from a manual to an automated process using the optimal means to mechanically stab a sinker bar/wireline jar assembly into the top of the drill pipe. The proposed mechanical wireline-tool stabbing system would be installed to: • Remove the wireline sinker-bars/overshot from the pipe through the top drive, wireline BOP, and split traveling block. • Hold the wireline sinker-bars/overshot while removing the inner core barrel on the rig floor and making up a new drill pipe connection, • Reinsert the wireline sinker-bars/overshot into the pipe through the split traveling block, wireline BOP, and top drive.  Please supply recommendations for a mechanized stabbing guide in the derrick to insert the coring wireline tools into the drill string at the top of the traveling block.

4.2.2.5. Mechanized Core Handling System This technology was not available on the ODP research vessel. Please refer to Attachment III for background information on the present core handling routine.

The scientific community is interested in increasing the amount of recovered core by increasing the drill pipe size (possible drill pipe sizes are listed in Table 1). The APC piston-coring shoe has 2.44-in. ID; however, the soft sediments expand or are sucked in by the piston to fill the 2.62-in. ID plastic core liner. The ODP XCB/RCB rotary coring systems cut firm to hard formations to 2.312-in. OD core diameter. The ODP cores are removed from the inner core barrel in a 32-ft long butyrate plastic core liner tube, which is 2.822-in. OD x 2.62-in. ID (0.092 in. thick wall). A full 9.5-m ODP core weighs ~135 to 176 lb, depending on rock density and type (i.e., 2.5 g/cc sediment to 3.25 g/cc peridotite).

A larger 4.00-in. OD core would weigh 428 to 556 lb with the same rock types. The plastic core liner tube would be heavily loaded and would have to be held straight (i.e., supported to avoid core distortion) as it is removed from the inner core barrel and transported to the adjacent core handling area (for sampling and

0_Market Surv DE vendors15.doc 10 of 27 1/14/04 Drilling Equipment Market Survey

sectioning). Bending the core liner around corners could distort the core inside the liner, which would also reduce the scientific value. In the core handling area, the core liner is manually cut into 1.5-m long sections for sampling and is moved into the lab.

The proposed mechanical handling system for core removal would: • remove the core liner/core from the inner core barrel on the rig floor, • support the core liner to prevent buckling or bending, • move the core liner/core to the core handling area (~75 ft), and • allow core sectioning and sampling to take place.

4.2.2.6. Dual Elevator System  i) Recommendations on a dual elevator design to eliminate slip damage to the drill pipe.  ii) Recommendations on integrating the dual elevator system for drill pipe into a rig floor system that improves safety and operational efficiency.  iii) Cost for 350 and 500 ton dual elevators for the 5 in. x 5-1/2 in., 5-7/8 in., and 6-5/8 in. drill pipe.

4.2.2.7. Rig Instrumentation The IODP Rig Instrumentation System should have the following features: • Capable of recording various drilling and ship motion parameters from standard measuring devices. • Parallel recording of data in two different domains – minutes and seconds. • Capable of two-way communication with various data acquisition systems (i.e., MWD/LWD). • Capable of providing large, easy-to-read, user configurable display of ‘real-time’ data. • Capable of providing multiple displays (rig floor and remote stations). • Capable of providing real-time and historical views of data. • Easily configured print formats and printing capability. • Capable of recording selected data at 1-sec rate. • Print daily geolograph format logs.  Recommendations on a rig instrumentation system for gathering and displaying critical drilling data in real time to the driller and remote positions on the ship.

4.2.2.8. Subsea Television System • A subsea television camera with zoom capability rated for specified water depth complete with pan and tilt assembly, light assembly, and protective guide frame. Television camera should be capable of detaching from a protective frame on a 50-m tether. • A TV monitor located at Driller's control and in DP control room. • A surface control console with power supply, lighting and focusing and zoom control, pan and tilt control and winch control. • Winch unit with line tension/depth readout and data feed into rig instrumentation system. • A heave compensated subsea winch capable of handling a minimum of 9,144 m (30,000 ft) of cable is needed to reduce the effect of ship's heave on the subsea reentry system. The heave compensated subsea winch shall control the TV and sonar motion to within 4 in. (+/-2 in.) of deviation relative to the seafloor (within three vessel heave periods). The requirement is to remove greater than 95% of the ship's heave from the absolute motion of the subsea cable. The heave compensator will operate with vessel heave of 25 ft, vessel roll of +/-4°, vessel pitch of +/-5° and with vessel heave velocity not exceeding 5 ft/sec. Minimum heave periods of 6 sec are to be assumed. In the event of a mechanical or electronic system failure of the heave compensator on the subsea winch, the winch shall be able to operate as a standard winch. The subsea reentry winch control panel shall be easily accessible with simplicity of operation, operator friendly in cold weather, and with the capability to read the gauges in bright sunlight. • TV cable having sufficient length for the specified water depth and suitable for re-termination on rig. • Color sonar system (Mesotec color or equivalent) mounted with TV camera for search capability (for structures or holes) of large areas or in turbid water. The TV and sonar information is used to assist in locating objects on the seafloor and in reentering seafloor structures and holes.

0_Market Surv DE vendors15.doc 11 of 27 1/14/04 Drilling Equipment Market Survey

• A shock protected frame (to support the TV and sonar system) that is clamped around the drill pipe and deployed by running it up and down the drill string on the coax cable winch. The split guide that goes around the drill string is ~9-in. ID to go over drill pipe and ~18 in. to go over 16-in. casing.  Recommendation and cost for a subsea television system.

4.2.2.9. Guide Horn A drill pipe guide horn (Fig. 1) is a flared tubular (cone-shaped) structure located in the moonpool of a drill ship composed of an upper and lower section. The upper section extends from just below the rotary table at the rig floor elevation to the moonpool doors on the main deck. The lower section continues as a tapered split cylinder from just below the moonpool doors to just slightly past the keel of the drill ship. The tapered internal diameter is narrow at the top, starting at ~9 in. (ID) and flared at the bottom. Depending on the movement of the drillship, the ‘horn’ design allows a gently curved contact to occur with a major 350 ft radius, thus, providing a minimal bending stress riser on the drill string as it rotates. Normal bending stress in drill string is 60,000 psi; with bending limiters ~30,000 psi; with knobbies ~20,000 psi. By reducing stress risers, fatigue life of the drill pipe can be increased during normal operations.

The upper and lower sections of the guide horn are connected by means of a Cameron 18-3/4 in. 10 kpsi Hub Clamp. The lower section of the guide horn is split into two halves and is designed to ‘clam-shell’ around the drill string. When the two split-halves are mated, hydraulically actuated locking pins, with tapered profiles, positively lock both halves together. The entire lower section of the guide horn is supported by spider-beams. These sliding beams are mounted to and controlled by the moonpool doors located at the main deck level. This feature allows for deployment of large equipment and seafloor structures (e.g., reentry cones).  i) Recommendation and cost for a guide-horn configuration for the proposed drillship.  ii) Are both the lower and upper guide horn necessary to minimize drill string stresses?

4.2.2.10. Synchronous Condenser (Power Factor Correction) A synchronous condenser is required to provide a capacitive load to offset the lagging phase angle created by the power control circuitry, which optimizes the main engine load factor and fuel efficiency. The synchronous generator requires a continuous duty rating, a soft starter, an exciter regulator/power factor controller with maximum kVAR limiter rated for ~3000 kVAR, 4 pole, 1800 rpm, 4160 volts, 60 hertz.  Recommendation and cost on a synchronous condenser package.

4.2.3. Integrated Drill Pipe Handling, Racking, Laydown, and Storage Your guidance and experience on the options available for drill pipe handling would be valuable to our understanding of the current state of the art. We request that vendors provide options for both the post-1995 and pre-1995 drillship configurations listed in Attachment II for the following equipment.

4.2.3.1. Pipe Racker System Please provide recommendations for:  i) Ensuring the safety and efficiency of handling drill pipe and collars on the rig floor.  ii) Ensuring the safety and efficiency of handling drill pipe and collars to the rig floor from the storage area.  iii) Integrating the pipe handling system into a derrick and substructure.  iv) Storing the drill string in singles or triples. Drill pipe may be laid down for transits and picked up for drilling up to eight times per month.  v) Upgrading the driller's controls on a pre-1995 drillship as part of the pipe racker system.

4.2.3.2. Pipe Storage and Laydown A horizontal drill pipe laydown system that handles pipe in triples may be the most efficient system for a scientific coring vessel. Most new pipe handling systems store pipe as singles. Thus, IODP may have to break triples into singles for storage during transit. In addition, pre-1995 drillships may not have enough stability to transit with pipe in a triple configuration in the derrick. However, the selected IODP drillship may benefit from laying down the drill string in triples.  Recommendations on optimal means for pipe storage and laydown for the post- and pre-1995 drillships.

4.2.3.3. Derrick Modification for Tripping Drill String The nonriser vessel used by ODP was restricted to handling the drill string in doubles (with the top drive) during drilling operations, because of the addition of a passive heave compensator and a top drive inside the existing Dreco 147-ft derrick.  i) Recommendations on the optimal means of handling 90-ft triples using the top drive. A shorter top drive/traveling block/wireline BOP or compensated drawworks may be considered for the post- and pre-1995 drillships.  ii) Recommendations on racking stands of drill pipe in the derrick during bit trips.

4.2.3.4. Pipe Handling Options for Various Drill String Sizes There are three potential drill string configuration scenarios for IODP operations as shown in Table 2. The drillship would carry a working drill string and a back-up string on board at all times. The ship will also carry drill pipe with bend limiters, which are knobs (similar to tool joints or heavy wall drill pipe) fabricated on the pipe at 10-ft centers. The bend limiters, similar to heavy-wall pipe, may affect pipe handling.

IODP would run the lower string of drill pipe to the seafloor or to the crossover point before running the middle string. IODP would operate with the middle or upper string in the water column and through the moonpool. In heavy weather, knobbies (similar to heavy wall but cut from drill collar stock) are run through the moonpool to help handle bending stresses at the top of the drill string. The upper string with bend limiters could be used for coring operations in good weather vs. picking up the knobbies and it can also be used for running heavy casing strings.  i) Recommendations on the optimal drill string for scientific coring operations and its integrated drill pipe handling system.  ii) Various pipe handling configurations that could be considered (e.g., the drill string and/or BHA stood back in the derrick, laid down in singles, or laid down in triples).  iii) The derrick rating, set back capacity, and pipe handling system requirements should be defined, documented, and costsed for the following three drill string options (Table 2) with the three water depths and total depths shown in Table 3.

4.2.3.5. Driller's Controls The driller's controls require readouts on information that will assist the driller in handling the pipe on board and to expedite tripping pipe, along with monitoring drilling parameters during coring and drilling operations.  i) Recommendations on optimal driller's controls to monitor drilling parameters and operate the pipe handling system.  ii) Recommendation on integration of the coring winch controls in the driller's dog house.

4.5. TOP HOLE DRILLING PACKAGE 4.5.1. Introduction The purpose of the Top Hole Drilling Package (THDP) is to increase hole cleaning capability and to maintain a required borehole pressure gradient in a riserless drilling mode, using a rotating head with a mechanical seafloor pump and mud return line to the ship to:

• Mitigate various pressure related geotechnical hazards at shallow penetration depths, such as pressured water and gas sands, by imposing the optimum circulating pressure to improve wellbore stability and hole cleaning without increasing mud weight; • Mitigate formation fracturing and mud loss by controlling the pressure on the wellbore, using a seafloor pump either as an annular choke (i.e., to increase wellbore pressure) or as a mud lift pump in riserless mode (i.e., to eliminate the hydrostatic pressure effect of the mud column that would be in a riser); • Reduce the seafloor pollution and loss of mud caused by the "dump and pump method;" • Reduce the number and size of casing strings required during drilling operations (i.e., by extending casing setting depths to cover problem formations with fewer casings); and • Improve the ability to successfully wireline log the open hole.

4.5.2. Top Hole Definition Surface casing (13-3/8 in.) set <5000 ft below the mudline.

4.5.3. Equipment Handling System The THDP stack requires a handling system to facilitate transport and mating of the Lower and Upper THDP from their storage to running positions.  Recommendation and layout of a handling system for the Upper and Lower THDP in the moonpool to facilitate transport from the storage to an operational position.

4.5.4. THDP System Configuration (Figs. 2, 3, and 4) The reentry, casing, and THDP system would consist of the following elements:

4.5.4.1. Guide Base and Conductor The rig’s normal drill string would be used to run a subsea guide base with a small structural casing (maximum 20-in.) jetted-in using normal offshore practice. A low-pressure housing suitable for 20-in. structural casing would be integrated into a temporary guide base (TGB). The housing would be able to accommodate 16-in., 13-3/8 in., and a third smaller casing. The 16 in. is for use as a contingency structural/conductor casing string.

4.5.4.2. Lower THDP The Lower THDP consists of a dual ram package of blind/shear and variable pipe rams. It allows the operator to drill below the surface casing and mitigate potential hazards. Formation evaluation would be done using electric logs and downhole sampling tools run through the drill string. A 13-5/8 in. dual ram 10,000-psi BOP system with an extension spool to land the lower THDP into the structural casing will be used to maintain well integrity and safety.

Wellbore circulating pressure control would be imposed by a seafloor-mounted mud return pump, which also acts as a choke. The mud would be pumped up a return riser pipe to the vessel, where it would be

0_Market Surv DE vendors15.doc 15 of 27 1/14/04 Drilling Equipment Market Survey

conditioned for recirculation. The THDP would have a minimal seafloor BOP (two rams) and Rotating Head. The mud return riser (RR) pipe would require an offset rotary and tensioning system to tension and secure the mud RR string beneath the drill floor during operations.

A master hydraulic control panel would be provided with a hydraulic power unit. The master control panel would be capable of operating all functions of the THDP and providing readouts for all major systems. Hydraulic power would be supplied by electrically driven pumps on the master unit. The hydraulic power system would be designed such that each pump could be isolated for repairs without interfering with the operation of the other pumps.

Sufficient accumulator capacity would be provided to meet the criteria in API RP 16E (Control Systems for Drilling Well Control Equipment), October 1990. The control fluid would be biodegradable and protected against freezing to the environmental limits specified.

A driller's THDP control panel would be capable of operating all functions of the THDP and would give a clear indication of the status of the various functions on the THDP. A mini-remote control panel would also be located a suitable distance from the driller's panel in a nonhazardous area and capable of operating major THDP functions. A battery bank and battery charging system would be capable of providing standby electrical power to the driller's panel and the mini-remote panel in the event primary rig power is lost.

A hydraulically powered control umbilical reel containing an adequate length of umbilical would be required to run the control umbilical in up to 4000-m water depth. The hydraulically powered reel would be located in the moonpool area. A single THDP control pod would be located on the Upper THDP

4.5.4.3. Return Riser for Mud Circulation A second rotary set up on the rig floor would allow the 5-in. mud RR to be run from the rig floor. The 5- in. mud RR could be supported by a hydraulic tensioner system in the moonpool area. A power umbilical cable, to supply power and control to the Upper THDP, could be strapped to the 5-in. mud RR. Mud would be pumped down the normal drill string, and the seafloor pump speed (output) would be controlled to either add wellbore pressure (i.e., acting as a choke) or reduce wellbore pressure (i.e., acting as a lift pump). A mud RR flexible hose would connect the mud return riser of the THDP to the mud treatment and choke manifold. The mud RR system consists of: • A 5-in. drill string to act as a mud RR and to be used to run the THDP (maximum WD = 4000 m). • A tensioning system would compensate the mud RR. • An offset rotary and the iron roughneck could be used to makeup and run the mud RR while the drill string is in the hole. • The coring winch could be modified to include a third drum for use as a drawworks for the mud RR. • The derrick could incorporate a second crown and traveling block to run the mud RR. • The Upper THDP would fit within a standard BOP footprint (10 ft x 10 ft), be ~20 ft tall, and weigh ~75,000 lb in air.  Recommendations for the THDP handling equipment, including an offset rotary and tensioning system, elevators, iron roughneck, and derrick modifications to run, makeup, and retrieve the mud RR string beneath the drill floor.

4.5.4.4. Upper THDP The Upper THDP, consisting of a rotating head and seafloor dual gradient pump package, could be run over the drill string suspended on the 5-in. drill pipe mud RR. It would contain: • A twin duplex mud-lift pump system, with subsea electric motors for hydraulic power, properly sized and packaged for subsea operations. The Upper THDP would land and lock out with the rotating head and reduce the mud column gradient for the wellbore to the hydrostatic gradient of seawater at the seabed. • Valve manifold for suction and discharge of two duplex pumps, mud RR, and seafloor dump valve. • A control system to operate the Upper and Lower THDP packages.  Recommendations and layout for storing and handling the Upper and Lower THDP.

0_Market Surv DE vendors15.doc 16 of 27 1/14/04 Drilling Equipment Market Survey

4.5.4.5. Mud Processing Equipment A mud processing system is required for the Top Hole Drilling Package. The circulating rate could range from 750 to 1200 gpm with a maximum circulating pressure of 3500 psi. A mud/gas separator of the atmospheric-pressure type with a closed bottom needs to be provided. Linear or elliptical motion shale shakers are required for the THDP with a maximum capacity of 4550 lpm (1200 gpm).

A vacuum type degasser may be required in the mud return system immediately downstream of the shale shakers with its vent piping arranged to alleviate hazard from gas accumulation. The maximum throughput capacity would be 4550 lpm (1200 gpm), and the equipment needs to be rated for H2S service.

Solids control equipment (e.g., desander and desilter as a minimum) may be required downstream of the shale shakers. The suction and discharge lines and tanks related to this equipment must be properly arranged for maximum solids control effect. Minimum throughput capacities are 3800 lpm (1000 gpm) and 3000 lpm (800 gpm) for the desander and desilter, respectively.  Recommendations and layout of a mud processing system for a THDP

4.5.4.6. Choke Manifold, 3 in. I.D., H2S Service A choke manifold would consist of a minimum of two chokes with at least one power (remote) operated choke and one manually adjustable choke. In addition, it should include one straight bypass through the manifold, which should be rated for 5000 psi.  Recommendations and layout of a choke manifold for a THDP

4.5.4.7. Control Equipment for the Drilling Fluid System  Recommendations and layout of the control equipment for the drilling fluid system needed with a THDP, including: level totalizer, trip tank, drilling fluid return indicator, alarms for PVT, and a flow returns indicator.

4.5.5. THDP Operational Procedure (Figs. 2 and 3) The following operational sequence is envisioned for THDP operations:

• Run the guide base on 5 x 5-1/2 in. drill pipe and jet-in 20-in. structural casing to a depth of ~100 mbsf. • Run the Upper THDP (rotating head and seafloor pump package) on the mud RR pipe either using the drill string as a guide or with the THDP run as a guide-lineless package. • Core a test hole with a 9-7/8 in. bit through the Upper THDP and log. • Underream to 20-in., and set a 16-in. intermediate structural/conductor casing (if required by hole conditions). • Drill and core to targeted surface casing depth utilizing the Upper THDP. • Kill the well and pull the Upper THDP. • RIH and cement 13-3/8 in. surface casing above the formation interval. • RIH with the integrated Lower and Upper THDP (13-5/8 in. dual rams and dual gradient pump package). • Drill and core into the formation. • Evaluate the formation with wireline electric logs and downhole tools run through the drill string (4.125- in. pass through ID). • Abandon the hole in compliance with regulations. • Recover the integrated THDP.

4.5.6. Recommendations Please provide recommendations on the following items.  i) The configuration and spacing of an offset rotary with access to the iron roughneck on the rig floor for running the mud Return Riser of the THDP.  ii) The ability to accommodate a dual elevator system on the offset rotary table to minimize drill pipe damage when tripping the Return Riser.

5.0 WIRELINE LOGGING 5.1. ODP PROCEDURES When the total depth of a hole scheduled for logging has been reached, a series of activities are initiated to prepare the hole and rig floor for the logging operation. The borehole is conditioned and the hole is filled with a drilling mud such as sepiolite/seawater (8.9 ppg) to stabilize the hole. If the APC/XCB BHA and core barrel assembly is deployed, logging can commence directly through the bit with the use of a go-devil and the lockable flapper valve (LFV). If the RCB BHA and core barrel are deployed, the drill bit must be removed using one of three methods listed below: • The drill bit may be dropped at the bottom of the hole (if hole deepening will not occur) using a wireline activated mechanical bit release (MBR). • The drill bit may be dropped at the seafloor using an MBR but a reentry cone or Free Fall Funnel (FFF) is required to reenter the hole. • A pipe trip may be used to remove the bit at the rig floor and the hole reentered assuming a reentry cone or FFF is deployed.

Next, the base of drill pipe is placed at a depth of 50–100 m (164–328 ft) below the seafloor to provide confining pressure to the upper regions of the hole and to prevent the pipe from pulling out of the hole. Once the pipe is set, the rig floor is converted from drilling operations to logging operations.

5.2. HEAVE COMPENSATED LOGGING WINCH FOR IODP LOGGING A heave compensated wireline logging winch capable of handling a minimum of 11,000 m (36,000 ft) of 7-conductor, 0.48-in. O.D. cable is needed to reduce the effect of ship’s heave on the downhole logging tools. The tripping speed for the winch should be up to 500 m/min. The logging speed should be as low as 3 m/min. The logging line can be compensated by one of the following: • heave compensated winch drum, • other technically sound, viable concepts.

The heave compensated wireline logging winch shall control the logging cable motion to within 4-in. (+/-2 in.) deviation relative to the seafloor (within three vessel heave periods). The requirement is to remove greater than 95% of the ship’s heave from the absolute motion of the logging cable. The heave compensator will operate with maximum vessel heave of 25 ft, vessel roll of +/-4°, vessel pitch of +/-5°, and with vessel heave velocity not exceeding 5 ft/sec. Minimum heave periods of 6 sec are to be assumed. In the event of a mechanical or electronic system failure of the heave compensator on the logging cable winch, the winch shall be able to operate as a standard winch. The logging winch control panel shall be easily accessible with simplicity of operation, operator friendly in cold weather, and have gauges capable of being read in bright sunlight.  Recommendation and cost for a heave compensated logging winch.

I. SUMMARY OF CURRENT OPERATIONS

The Ocean Drilling Program (ODP) presently conducts coring, casing, and logging operations in the deep ocean worldwide. The U.S. National Science Foundation (NSF) intends that the ODP will be followed by the Integrated Ocean Drilling Program (IODP) after ODP ends on Sept. 30, 2003. In both ODP and the future IODP, coring sites are selected with the expectation that they will be normally pressured to total depth (TD) and will have minimal risk of encountering hydrocarbons. The holes are cored from a dynamically positioned drillship operating in riserless mode without a seafloor blowout preventor (BOP). Seawater is used as the circulating fluid with occasional mud sweeps to clean the hole. Cuttings and returns flow out of the hole to the seafloor. Wireline coring, sampling, downhole measurements, and wireline logging are currently conducted through a drill string and bottom-hole assembly (BHA) with 4-1/8 in. I.D. The bit has a 3.80-in. throat.

The Ocean Drilling Program typically consists of six operational segments or “legs” per year. Each average “leg” lasts ~60 days, consisting of a 4-5 day port call (to change crews/refuel/offload core/ load supplies and equipment), ~14 days of transit (from port- to-site/site-to-site/site-to-port), and ~41 days operating onsite. The ship usually visits multiple sites and cores multiple holes per site. The six legs conducted during each year have varied scientific themes but typically consist of

1. three sediment coring legs (for sea-level and climate change), 2. one shallow cased borehole leg (to install instrumentation or observe active geological features), 3. one cased reentry hole (for a borehole observatory in a seismogenic zone), and 4. one deep penetration (300–1000 m) through sediment and basement rocks.

Recent typical examples of these leg types are: • Leg 201 (Peru Biosphere) - climate change and microbiology in sediments, • Leg 203 (Equatorial Pacific ION) - an instrumented shallow cased borehole in ocean basement, • Leg 205 (Costa Rica Subduction Zone) - a borehole observatory completion, and • Leg 210 (Newfoundland Margin) - a deep, cased hole on a continental margin.

Exhibit 1 provides a set of documents for Legs 201 and 203 to demonstrate some of the drilling/coring data that is tracked during a normal leg. Exhibit 1 consists of (1) Project A evaluations (i.e., a brief precruise operations analysis of the project with a planned operations summary and time estimate), (2) Operations Resume (a summary of the actual project time by categories and significant details), (3) Time Distribution (actual project time by categories, which is equivalent to an IADC rig time report), and (4) Site Summary (coring data).

Project A evaluations provide the initial operations analysis of the scientific proposal submitted by scientists for drilling/coring by ODP. The Project A evaluations are used to

0_OVScCoringfinal2w_CT.doc Page 2 of 16 1/14/04 ATTACHMENT III Overview of Scientific Coring prepare cost and time estimates to assist the scientists in deciding which proposals to select and schedule as drilling legs for the next year. The remaining documents are created and updated during the leg and provide a record of how much time was spent on the various drilling/coring activities.

II. TARGET SECTIONS

Targets were defined by the scientific community per the Conceptual Design Committee (CDC) Report. The Community Survey and Synthesis Target sections below were excerpted from the CDC Report. The report is located at: http://www.joiscience.org/ USSSP/cdc/default.html.

1) Community Survey Defining the essential operational, technical, and scientific capabilities of a single non- riser drill ship to meet the needs of the future Integrated Ocean Drilling Program (IODP), required a census of the broad geographic and lithologic array of future drilling targets. To accomplish this, input was solicited from several scientific groups using a target section template (i.e., a method to describe the characteristics of each drilling target and the operational capabilities that would be required to address a specific scientific theme). These individuals, in their capacity as chairs, represented hundreds of members of the U.S. and international scientific communities involved in scientific ocean drilling. They were charged with developing target drill sites that cover the broadest array of drilling and sampling capabilities required to meet the scientific objectives (as defined by the members of their sessions and planning groups). Information was solicited about the following characteristics of each proposed target section:

• Model site location and description • Scientific objective • Water depth range (minimum and maximum depths) • Maximum penetration below the seafloor • Lithology and thermal gradient expected • Conditions (degree of fractures, porosity, pore pressure, presence of volatiles) • Recovery required; maximum core disturbance tolerated • Sampling needs (core sampling, number of holes, desired core diameter, in situ sampling and testing needs) • Down-hole logging needs • Endurance capabilities required (days at sea without resupply) • Environmental conditions (wind, sea state, temperature, ice cover conditions) • Other program requirements

2) Synthesis Target Sections The goal of using target sections was to efficiently describe the performance specifications for the non-riser vessel, and especially to identify those characteristics that might be used to differentiate among possible platforms. The submitted target sections were grouped into nine "synthesis" target sections, which were defined on the basis of the range of environments to be drilled and the technology required to achieve

0_OVScCoringfinal2w_CT.doc Page 3 of 16 1/14/04 ATTACHMENT III Overview of Scientific Coring the scientific goals. The synthesized sections were returned to the original contributors for review to ensure that their needs and goals were appropriately represented. Expert input was also solicited on the down-hole logging needs for all nine synthesis target sections.

The synthesis target sections (Target Sections 1-9; Exhibit 2) represent the following scientific themes:

• Observatory • Rifting Processes • Convergent Margin • Large Igneous Province • Oceanic Crust • Hydrothermal System and Massive Sulfide Deposit • Deep Ocean Sediment • Passive Margin Stratigraphy • Carbonate Reef, Atoll, or Bank

III. INTRODUCTION

1) OCEAN DRILLING PROGRAM (ODP)

ODP represents a long-term, international partnership of scientists, oceanographic institutes, and national governments dedicated to unlocking the history, evolution, and structure of the world’s oceans through the recovery of core samples from below the ocean floor. The study of these sediment and rock cores helps to unravel the history and evolution of the Earth and it's climate. IODP will follow in the footsteps of ODP with the goal of using improved drilling equipment and ship laboratories to continue to provide cutting-edge scientific research capabilities.

The science operator of the ODP is Texas A&M University (ODP/TAMU). The logging operator is the Borehole Research Group from the Lamont –Doherty Earth Observatory of Columbia University. The JOIDES Resolution (JR) has been the primary drilling platform for ODP. The JR, a former oil industry drillship, was originally registered as the Sedco/BP 471. The JR was converted for scientific ocean drilling work in 1984 and is on an exclusive long-term contract to ODP. Detailed about the vessel and its equipment as operated by ODP is located at: http://www-odp.tamu.edu/publications/tnotes/ tn31/jr/jr.htm.

2) PROGRAM MANAGEMENT

The Joint Oceanographic Institutions, Inc. (JOI) manages ODP on behalf of the U.S. National Science Foundation (NSF) and its international partners (Fig. 1). The program is funded through NSF with significant financial contributions from 22 member countries.

0_OVScCoringfinal2w_CT.doc Page 4 of 16 1/14/04 ATTACHMENT III Overview of Scientific Coring

0_OVScCoringfinal2w_CT.doc Page 5 of 16 1/14/04 ATTACHMENT III Overview of Scientific Coring

Overall scientific advice for ODP is provided by the Joint Oceanographic Institutions for Deep Earth Sampling (JOIDES) through an assortment of advisory panels staffed by international scientists and representatives from industry and government agencies. JOIDES is an international network of scientists from universities, oceanographic institutions, and government agencies in the ODP member countries.

ODP is the successor to the Deep Sea Drilling Project (DSDP), which was operated by Scripps Institution of Oceanography from 1968 to 1983 using the drillship Glomar Challenger. In this 15-year period, DSDP operated 96 scientific expeditions covering over 600,000 km (375,000 miles) of ocean, and 1,092 holes were cored at 624 sites yielding more than 96 km (60 miles) of deep ocean core.

Since 1985, ODP has completed 106 scientific expeditions covering 624,626 km (388,135 miles) of ocean and circumnavigated the globe. More than 1741 holes have been cored at 650 sites, and 213 km (132 miles) of deep ocean core have been recovered (69% average recovery).

3) INTEGRATED OCEAN DRILLING PROGRAM (IODP)

ODP will terminate on September 30th, 2003. The NSF; Japan’s Ministry of Education, Culture, Sports, Science, and Technology (MEXT); and other international partners are creating an Integrated Ocean Drilling Program (IODP), which will be the successor program to ODP and will involve more than one drilling platform. NSF will select a U.S. science contractor to operate a riserless drillship capable of performing scientific coring operations in an optimal manner. The operational capabilities of the IODP riserless drilling vessel should meet or exceed the existing capabilities of the JR, as outlined in the Conceptual Design Committee (CDC) Report located at: http://www.joiscience.org/USSSP/cdc/default.html.

4) ODP DRILL SITE APPROVAL

To avoid areas of potential hydrocarbon accumulation, personal risk, or significant ecological risk, the proposed locations are rigorously reviewed by a safety panel of recognized experts to ensure that the formations appear to be normally pressured to total depth (TD) and that encounters with hydrocarbons are avoided. As cores are recovered, they are monitored continuously to determine the composition and concentration of hydrocarbons, and coring is terminated immediately if anomalous levels of migrated hydrocarbons or mature hydrocarbon precursors are detected; therefore, no riser or BOP has been used by ODP to date. All BOP, riser, riser tensioner cylinders and wire pulleys, and surface mud handling shaker/treatment equipment were removed from the JR prior to its use by ODP. An emergency kill mud pit with ~400 bbl of 12.5 ppg mud is maintained at all times. Seawater is circulated with occasional viscous gel pills to clean out cuttings, with returns to the seafloor. Hydrostatic pore pressures are typically seawater gradient.

IV. CURRENT ODP EQUIPMENT

1) EXISTING ODP RESEARCH VESSEL- JOIDES RESOLUTION

The JOIDES Resolution drillship was reclassified by ABS as a research vessel. The ship is 143 m (471 ft) long, 21 m (70 ft) wide, and displaces 18,934 metric tons (18,636 long tons). The vessel has an ABS Ice Class 1B ice-strengthened hull and is equipped with a dynamic positioning system using 12 fixed thrusters and two main screws. The thrusters are capable of keeping the vessel within an excursion radius of 2% of water depth in winds of 23 m/s (45 kt), significant wave heights of 5 m (16 ft), and surface currents of 1.3 m/s (2.5 kt). The vessel has an operational endurance of 100 days with a fuel capacity of over one million gallons (3785 m3).

The vessel can operate in water depths of 8,200 m (26,900 ft) and can suspend a static load of 9,150 m (30,000 ft) of drill pipe. Bottom-hole assemblies are normally 9 to 12 each 8-1/4 in. drill collars with a transition joint and two stands of 5-1/2 in. drill pipe. Drill pipe generally has S135 or S140 grading, and tool joints were specially manufactured to maintain clearance for coring tools. About 3500 m (11,484 ft) of 5 in. drill pipe is run above the BHA, with 5-1/2 in. drill pipe in the remainder of the drill string. Hole angle is checked with core orientation tools and typically remains at 0-5° deviation from vertical without stabilizers or directional control. A guidehorn with a 350 ft radius curvature extends from the rotary to below the bottom of the ship to limit drill pipe bending and fatigue due to vessel roll and pitch.

The drilling equipment on board ensures that operations can be maintained in harsh environments. The derrick is 53 m (174 ft; including the water table and crown) tall and the top breaks over to pass under the Bridge of the Americas to navigate through the Panama Canal. The derrick substructure is 7 m (22 ft) tall from the main deck of the ship to the rig floor. The JR’s derrick is rated for 544,200 kg (1,200,000 lb), and is equipped with a variable speed electric top drive, which is constrained in the derrick by rails. The passive heave compensator, the largest in the world when it was installed, has a 20 ft stroke and is rated for 362,800 kg (800,000 lb) when compensating or 545,450 kg (1,200,000 lb) when locked. Under normal environmental conditions, the original passive heave compensator system can only control weight on bit with a 10 to 15,000 lb fluctuation; therefore, diamond and PDC bit performance suffered as a result. An Active Heave Compensator was added in 1999 and now controls weight on bit (WOB) with 5000 to 8000 lb fluctuation. The ship is also fitted with a Varco Iron Roughneck, dual elevator system and horizontal pipe racker for triple stands of 12.7 and 13.97 cm (5 and 5-1/2 in. O.D.) S-140 drill pipe.

2) CORING SYSTEMS

Core samples are collected by continuous wireline coring into the Earth's crust. The current depth penetration record is 2100 meters (6926 ft) below seafloor (mbsf) in 3475 m water depth. The shallowest water depth the vessel has operated in is 28 m (92 ft)

0_OVScCoringfinal2w_CT.doc Page 7 of 16 1/14/04 ATTACHMENT III Overview of Scientific Coring and the deepest water depth is 5890 m (19, 620 ft). Most scientific holes are cored to an average subsurface open hole depth between 200 to 1200 mbsf. If the formation is stable, the open hole penetration depth may reach 1600 mbsf without any casing or reentry cones. Depths deeper than 1600 mbsf are rarely cored without casing. Inner core barrels, temperature probes, fluid samplers, and other special tools are free-fall deployed or run through the 4-1/8 in. I.D. drill pipe on a special coring wireline. The coring wireline passes through a wireline BOP and pressured wiper sleeve that permits circulation down through the drill string during wireline work. Some temperature, pressure, conductivity, and resistivity sensors are run on the core barrels or in special bit subs. Wireline electric logs are run on a heave compensated logging line.

Advanced Piston Corer/Extended Core Barrel Systems The 9.5 m (31.17 ft) long by 5.9 cm (2-5/16 in.) cores are retrieved by the Advanced Piston Corer/Extended Core Barrel (APC/XCB) coring systems by a wireline through the 5 and 5-1/2 in. O.D. tapered drill string, which has a 10.47 cm (4-1/8 in.) minimum I.D. ODP owns all equipment that goes below the keel of the vessel. The APC inner core barrel is deployed (and recovered) using the coring wireline to avoid premature release of the shear pins, which determine penetration force of the barrel into the sediment. Holes in soft sediments are typically cored to refusal (i.e., usually ~300 mbsf) using the APC. Holes in compacted to moderately indurated sediments are cored to refusal to ~500-800 mbsf with the XCB. The BHA is the same for the APC and XCB systems. The BHA uses 8-1/4 in. O.D. (20.9 cm) drill collars. The APC/XCB BHA is run with an 11- 7/16 in. OD by 2.44 in. core I.D. (29.0 cm x 6.2 cm) four-cone tungsten carbide insert core bit or 10-1/8 in. PDC bit. Additional information on these coring systems is located at: http://www-odp.tamu.edu/ publications/tnotes/tn31/tn31.htm.

Rotary Core Barrel System Hard sediments and basement rocks are cored using the Rotary Core Barrel (RCB) system with an 8-1/4 in. (20.9 cm) BHA. The RCB system uses a 9-7/8 in. O.D. by 2- 5/16 in. core I.D. (25.1 cm x 5.9 cm) four-cone tungsten carbide insert core bit. Additional information on this coring system is located at: http://www- odp.tamu.edu/publications/ tnotes/tn31/rcb/rcb.htm. Present ODP Core Handling Routine on the JOIDES Resolution A core bit (i.e., open-throated TCI roller-cone or PDC bit) is run with an 8-1/4 in. coring BHA (core barrel and 5-10 drill collars) on a 5 in. x 5-1/2 in. drill string. The drill string and BHA have a 4-1/8 in. minimum ID. The inner core barrel is run on a coring wireline (APC piston corer) or free-fall deployed down the drill string (XCB and RCB rotary corers). A split crown and traveling block allows the wireline to run vertically into the pipe at 230 m/min., using a drawworks type coring wireline winch.

When the inner core barrel and newly cut core reach the rig floor, the pipe is set in the elevators and the knobby joint below the top drive is removed (like a “Kelly”) to expose the top of the inner core barrel. The coring wireline (Otis “GS” overshot, wireline jars, and sinker bars) are detached from the loaded inner barrel, which is removed from the pipe and set in a nearby shuck. The APC has a stroke rod that must be removed and collapsed for handling.

0_OVScCoringfinal2w_CT.doc Page 8 of 16 1/14/04 ATTACHMENT III Overview of Scientific Coring

An empty inner core barrel is put in the open pipe and free-fall deployed (or run on the wireline). A joint of pipe is added to the drill string, and the bit is washed to the bottom of the hole to take the next core. The loaded inner core barrel is taken from the shuck and laid down with the coring-shoe end in a vise. The core catcher and core shoe are unscrewed manually, and the exposed butyrate plastic core liner and core is removed from the inner core barrel, which sometimes requires assistance from an air winch. The core liner and core are hand carried to the core-receiving platform for sectioning, labeling, and processing by technicians and scientists. The inner core barrel is washed out, a new core liner is installed, and a shoe and refurbished core catcher is added. The inner core barrel is stored back in the rig floor shuck ready for the next core.

Functional Steps for Core Recovery (see Fig. 2) 1. Inner core barrel pulled from BHA with overshot and wireline. If APC, remove rod and set core barrel in shuck. Install new inner core barrel and make up drill pipe connection. 2. Core barrel transfer to rig tugger at rig floor. 3. Core barrel laid out horizontally on rig floor. 4. Cutting shoe broken off inner core barrel. 5. Core liner clamp attached to butyrate core liner. 6. Core liner pulled out of inner core barrel. 7. Core liner with core is hand carried to core handling area and laid out for inspection and cutting into 1.5-m sections. 8. Clean and redress inner core barrel for next core run & store in shuck.

3) CORING WINCH

A split crown and traveling block permit a high-speed coring wireline to be run through the drillstring. The Passive Heave Compensator, hook, top drive, and swivel have 5 in. openings on the centerline to accommodate core barrel operations. The drill floor is equipped with a double-drum high-speed drawworks for core barrel retrieval by coring line. This system allows core barrels and tools to be run and retrieved by wireline at rates of ~200 m/min, which permits rapid continuous coring.

4) POSITIONING AND REENTRY CAPABILITY

New core sites are located using Global Positioning Satellite (GPS) fixes and are confirmed with 3.5 and 12.0 kHz precision depth recorder or single channel seismic lines. Using GPS, the ship can position itself within 25 m of a location for spudding or reentry of a hole.

A 12 to 18 kHz commandable release positioning beacon is dropped on each site for positioning. Multiple holes may be drilled on each site using one beacon for 10-20 m offsets. The JR is equipped with a dynamic positioning system using 12 fixed thrusters and two main screws capable of keeping the vessel within a radius of 2% of water depth in winds of 23 m/s (45 kt), significant wave heights of 5 m (16 ft), and surface currents of 1.3 m/s (2.5 kt).

Most holes are spudded without viewing the seafloor, unless there is a potential seafloor obstruction or a drill site must be located precisely on a scientific target. A TV and sonar frame (i.e., the “Vibration Isolation Frame” – VIT) can be deployed over the drill pipe, if necessary, and lowered to the seafloor by means of an armored coaxial cable and winch, which is located in the ship's moonpool area. No ROV or divers are onboard the JR under current ODP operations.

The TV-sonar system also can be used to provide visual observation of the seafloor during reentry of an existing borehole. Sonar can be used to locate objects that are initially out of camera range (i.e., such as reentry cones or bare holes in the seafloor). Reentries are routinely made within 15 min by offsetting the surface position of the ship to move the suspended drill string/VIT until the bit can be lowered into the existing hole.

5) WIRELINE LOGGING

When the total depth of a hole scheduled for logging has been reached, a series of activities are initiated to prepare the hole and rig floor for the logging operation. The borehole is conditioned by pumping a viscous mud into the hole to flush remnant cuttings from the borehole, the bit is run up and down to break through any bridges or swelling clays and finally, the hole is filled with a drilling mud such as sepiolite/seawater (8.9 ppg) to stabilize the hole. The next step is determined by the type of BHA used. If the APC/XCB BHA (3.75 in. landing shoulder and 3.8 in. I.D.) and core barrel assembly is deployed, logging can commence directly through the bit with the use of a go-devil and the lockable flapper valve (LFV). If the RCB BHA (2.3125 in. I.D. throat) and core barrel are deployed, the drill bit must be removed using one of three methods listed below:

1. The drill bit may be dropped at the bottom of the hole (if hole deepening will not occur) using a wireline activated mechanical bit release (MBR). 2. The drill bit may be dropped at the seafloor using an MBR but a reentry cone or Free Fall Funnel (FFF) is required to reenter the hole. 3. A pipe trip may be used to remove the bit at the rig floor and the hole reentered assuming a reentry cone or FFF is deployed.

Next, the base of drill pipe is placed at a depth of 50–100 m (164–328 ft) below the seafloor to provide confining pressure to the upper regions of the hole and to prevent the pipe from pulling out of the hole. Once the pipe is set, the rig floor is converted from drilling operations to logging operations.

0_OVScCoringfinal2w_CT.doc Page 11 of 16 1/14/04 ATTACHMENT III Overview of Scientific Coring

To prepare the rig floor for logging, the top drive is pushed back and the wireline is threaded through the derrick, winch, and wireline heave compensator (WHC). The first logging string, typically the Triple Combination, consists of a series of probes measuring temperature, dual induction resistivity, density, borehole dimensions (caliper), porosity, and gamma ray. The second tool string is typically a micro-resistivity and sonic tool string, which acquires electrical resistivity borehole images, borehole dimensions (caliper), dipole shear sonic, and gamma ray measurements. The third tool string deployed may be a specialty tool such as a vertical seismic profile, a magnetometer or a geochemical tool.

Rig crews assist the single logging engineer with tool rig up/down and run the wireline- logging winch.

6) LOGGING WINCH, HEAVE COMPENSATOR, AND DATA ACQUISITION SYSTEM

A wireline logging winch with 9,144 m (30,000 ft) of 7-conductor, 0.46 in. O.D. cable is located at the aft end of the horizontal pipe-handling catwalk, adjacent to the WHC. The logging data acquisition system (DAS) is also located in the aft end of the catwalk in a separate cab.

The WHC is a large hydraulic ram with a wireline sheave on one end and is designed to reduce the effect of ship's heave on the downhole tool. The WHC responds to the ship's heave by adding or removing cable slack to decouple the movement of the ship from the desired movement of the tool string.

The DAS is located just port and forward of the helipad. This system contains two PC processors and numerous control and power modules that communicate with the downhole tools during logging operations. The DAS is also capable of communicating with all labs and workplaces on the ship and an intercom link exists with the winch shack.

7) HOLE CONDITIONS

Sediments Hole conditions in oceanic sediments range from relatively stable sectons in inert, soft, carbonate oozes (i.e., many carbonate holes will withstand 1700 m open-hole sections), to unstable flowing sands, corals, boulders, and swelling clays (i.e., unstable holes that require repeated reaming and inhibited seawater mud for logging).

Igneous Rocks Basement rocks vary in cohesiveness and hardness (e.g., unstable young pillow basalts, hard rugose fractured basalts, or softer plutonic rocks with large grains).

0_OVScCoringfinal2w_CT.doc Page 12 of 16 1/14/04 ATTACHMENT III Overview of Scientific Coring

Temperatures At water depths >500 m, the seafloor temperature is commonly between 2° to 4°C (36° to 39°F). At 1000 mbsf, temperatures typically range between 140°C (284°F) in 6-Ma old crust to ~40°C (104°F) in 40-Ma old environments. Some coring is conducted in temperatures ≥300°C (572°F) associated with active hydrothermal vent environments.

Stress Effective vertical stresses increase almost linearly with depth of burial from 0 bars (0 psi) at 0 m penetration to 1120 bars (16,408 psi) at 6000 m penetration.

8) CASING & CEMENTING

Deep holes, holes in unstable formations, and instrumented “observatory” holes can be equipped with Reentry Cones (on level sediment sites) and nested casing strings. A nested casing system is used with 20 in., 16 in., 13-3/8 in. and 10-3/4 in. casing hung in a mudline housing, which is supported by a reentry cone. Reentry Cones, casing, and casing tools are kept on the rig in the event that they are needed unexpectedly. The casing is run by the rig crew (i.e., no casing crews are used). A rotational release Dril- Quip quad-casing hanger system for Reentry Cones can hang four casing strings:

(1) 20 in. casing (washed-in or in 26 in. hole); (2) 16 in. casing (in 21-1/2 in. hole); (3) optional 13-3/8 in. as casing or liner (in 17-1/2 in. hole); and (4) 10-3/4 in. (in 14-3/4 in. hole as casing or liner).

A typical three casing installation might consist of the following procedures: (1) ~60-80 m of 20 in. casing jetted-in with the Reentry Cone, (2) coring a 9-7/8 in. hole to ~300-800 m and then opening to 21-1/2 in., (3) running 16 in. casing and cementing, (4) coring a 9-7/8 in. hole to 800-1500 m then opening the hole with a 14-3/4 in. bit, and (5) running 10-3/4 in. casing or liner and cementing.

The current vessel has a typical Halliburton HT-400 dual pump cementing skid with dual 10 bbl measuring tanks and a 20 bbl recirculating tank. The rig crew operates the cementing unit as required (i.e., no service hands). Casing cementing is typically based on an annular cement column of ~100-200 m of 15.6 ppg API Class G neat cement using a single float shoe and DP wiper plug/SSR top plug system. Retarders, fluid loss additives, etc. are rarely used but could be added to the fresh mixing water if required.

9) ALTERNATE CORING EQUIPMENT

Diamond and PDC bits can also be used in conjunction with the Pressure Core Sampler (PCS), mud Motor Driven Core Barrel (MDCB), and 7-1/4 in. bit Advanced Diamond Core Barrel (ADCB). Equipment and operating techniques are continuously refined and enhanced in response to changing scientific requirements, and new or modified equipment, techniques, and tools are function tested on the rig, if they add to the scientific objectives.

10) ENVIRONMENTAL CONDITIONS AND VESSEL MOTION

The successor scientific drilling vessel must be stable enough to maintain operations in a multitude of environmental conditions and air and water temperatures ranging from equatorial heat to sub-arctic cold. The ship is oriented into the prevailing environmental conditions (wind, seas, approaching storms, ice); however, as the waves/swell/wind/ currents change, the ship can follow as it is capable of rotating 360° during drilling/coring operations. Other forcing functions may include temporary loop currents to 5 kt and broken pack ice for high latitudes.

11) DRILL STRING

ODP currently considers a working drill string to consist of 3500 m of 5-in drill pipe and 1500 m of 5_-in drill pipe. ODP carries a back-up string on board the drill ship at all times. ODP runs 5-in drill pipe to the seafloor or to the cross-over point of 3900 m before running 5_-in drill pipe. ODP operates with 5_-in drill pipe in the water column and through the moonpool. In heavy weather, knobbies (similar to heavy wall but cut from drill collar stock) are run through the moonpool to help handle bending stresses at the top of the drill string.

The existing S135 and S140 5 in. x 5-1/2 in. drill pipe and 8-1/4 in. BHA has a 4-1/8 in. I.D. throughout, including pipe joints, to permit passage of coring and downhole measurement tools. The practical operational depth limits for the present drill string on the JR under various environmental conditions are available online on the ship toolsheet in Technical Note 31 located at: http://www-odp.tamu.edu/publications/tnotes/ tn31/jr/jr.htm.

12) SAFETY

All drilling contractor and science program supervisory personnel are required in general to have oil field and/or scientific coring experience and training that qualifies them for their specific roles. Safety is the primary consideration in planning and performing all operations, and it is considered to be the collective and individual responsibility of everyone aboard. The direct responsibility for maintaining safe working conditions on the rig floor and deck of the ship rests with the contractor because their

0_OVScCoringfinal2w_CT.doc Page 14 of 16 1/14/04 ATTACHMENT III Overview of Scientific Coring crews and heavy equipment perform the work. The science operator's representative has input on safety issues as well and works with the drilling contractor. The contractors safety program should strongly encourage direct worker participation in safety planning and implementation. An active safety training program is mandatory for all personnel. Contractor personnel are required to pass marine survival and drill floor certification under the contractor’s safety program.

The science program supervisors and lab personnel share a mutual commitment with the contractor to maintain safe operations, and all operations are discussed with the contractor in advance to facilitate proper pre-planning, evaluate any safety issues, and assign proper personnel.

13) SCIENCE PROGRAM’S KEY PERSONNEL

Operations Manager (1 person/24 hr): The science program’s senior representative on board and is responsible for detailed operational planning and execution of the leg, interfaces between the scientists and drilling contractor’s OIM, provides a general safety oversight function on the rig floor and ship deck, and is specifically charged with H2S and hydrocarbon safety. Responsible for general oversight to ensure safe handling of special coring and sampling tools and pressured core samples, and proper make up and testing of coring and special tools. Has authority to slow or terminate coring operations to ensure safety. Operations Engineer (1 person/12 hr): If one is assigned to the leg, the person assists the drill crew with safe handling of science program's special coring and sampling tools and pressured core samples. Lab Officer (1 person/12 hr) Supervises the lab crew and oversees scientific operations in the lab. Asst. Lab Officer (1 person/12 hr) Essentially the same responsibilities as the Lab Officer, but works the opposite shift to ensure 24 hr coverage. Staff Scientist (1 person/12 hr) Responsible for interfacing with the two Co-Chief scientists and scientists and Lab Officer to insure that core description, sampling, lab work, and sample archiving are in accordance with the leg scientific objectives and program policies. Logging Staff Scientist (1 person/12+hrs) Responsible for interfacing with the operations manager, two Co-Chief scientists, staff scientist, and shipboard scientists to insure that all logging operations (wireline and LWD), data acquisition, and data dissemination procedures are in accordance with the leg scientific objectives. Core Technician (2 persons/12 hr) Drilling sub-contractor is to provide one each experienced core technician (CTs) per 12-hour tour for each scientific expedition (leg). CTs assist with the assembly, make-up, deployment, operation and shipboard repair of “third-party” wireline coring and specialty tools. Directly monitor and facilitate 24-hour drilling/coring operations.

Proposal No. 499-Rev (Equatorial Pacific Site for Intl. Ocean Network) Project Summary A. SUMMARY OF OPERATIONAL OBJECTIVES: * Establish a cased/cemented reentry hole (OSN-2) for later wireline reentry installation of ION instrument package * consisting of broadband, triaxial borehole, and triaxial high frequency seismometers and a broadband hydrophone. * Drilling program consists of a single site with 2x APC, an RCB pilot hole (wireline logged), and cased reentry hole. * Proposed drill site is located on a fast-spreading ocean lithosphere, age 10-12 Ma, and is a potential reference site. * Site is located in the equatorial western Pacific at 5° 17.566' N latitude and 110° 4.579' W longitude. * Site is a priority location for both the International Ocean Network (ION) and the Ocean Seismic Network (OSN). * A site survey was previously conducted and Leg 138 drilled a transect of APC holes for paleoceanography. * Estimated water depth is 3878mbrf w/sediment thickness of 116m and basement penetration of 100m. * Total depth of pilot and rentry holes anticipated to be 4104mbrf or 226mbsf. * There are no anticipated environmental or safety considerations. * Observatory will ultimately be connected to a buoy and satellite communications established. * Full data streams (high frequency channels in particular) will be retrieved annually when buoy is serviced. * There are no significant drilling or formation problems anticipated. * Assumed starting port of Acapulco, Mexico and ending port of Balboa, Panama. Est. Recovery (m): Sediment: 220 & Basement 72 B. TOTAL ESTIMATED DAYS REQUIRED FOR LEG: Leg Starts: Acapulco, Mex dd-mon-yy Drilling: Logging: On-site: Transit: Total: Leg Ends: Balboa, Pan dd-mon-yy 14.7 1.1 15.8 11.2 27.1 C. NON-STANDARD HARDWARE OR EQUIPMENT REQUIRED: * A limited single channel reflection survey will be required prior to deployment of the positioning beacon. * A single reentry cone plus a spare will be required for the installation. * A total of ~60m of 16" 75 lb/ft casing and ~160m of 10-3/4" 54 lb/ft casing will be required. * The 10-3/4" csg and 4-1/2" instrument deployment string w/instrument pkg must be cemented in basement. * Deployment of standard wireline logging tools in the RCB pilot hole will require the use of a bit release. * A compliment of ION/OSN engineers and/or scientists will likely be required (2-4 additional berths?). * D. ODP/TAMU/TECHNICAL STAFFING TEAM:

* Assigned Project Manager/Staff Scientist: P. Blum, Operations Manager: TBD * Lab Officer: TBD, and Special Tech Assistance TBD E. SUMMARY OF OPERATING EXPENSES : Note: Cost data from attached "detailed spreadsheets". Hardware: $0 Functional Shipping: $0 Rentals: $0 Functional Hardware: $0 Shipping: $0 Subtotal Hardware: $0 Subtotal Shipping: $0 Total Hardware+Shipping+ Rentals: $0 F. COMMENTS, IDENTIFIED RISKS, OR SPECIAL CONCERNS: * This should be another standard long term observatory instrumented borehole effort. * Instruments will not be installed using the drill ship. They will be installed later using wireline reentry techniques. *

DRILLING EQUIPMENT DESCRIPTIONS

The following equipment descriptions are based on the existing systems in use by ODP for scientific coring on the JOIDES Resolution. The derrick equipment is unique as it must accommodate a wireline retrievable core barrel. The other drilling equipment is typical of an older drillship.

1. Derrick The current vessel is equipped with a 147-ft Dreco Derrick (Fig. 1), designed and built to API Spec 4E. It is 40 ft x 40 ft at the base and 14 ft x 14 ft at the crown. The water table was replaced in 1998 to accommodate the active heave compensator (AHC) upgrade. The A-frame (24 ft; Fig. 1) on the crown breaks over to clear bridges at the Panama Canal and various other international ports. The derrick has 70-ft V-doors fore and aft. The derrick is rated to hoist 1,200,000-lb static and 800,000-lb dynamic load. The drill floor is designed for 337,000 lb of set back with 30-kt winds and 12-ft seas. Located on the port side of the derrick is a guide track and dolly system to accommodate the Western Gear passive heave compensator, the Dreco traveling block and the Varco power swivel, which breaks back and stores for tripping pipe. The nonriser vessel JOIDES Resolution (formerly Sedco/BP 471) currently used by ODP is restricted to handling the drill string in doubles during drilling operations, because of the addition of a passive heave compensator and a top drive inside the existing Dreco 147-ft derrick.

2. Crown Block The Dreco Crown Block (Fig. 1) is rated for 1,400,000 lb and designed and built to API Spec 8A. The crown block has a split sheave configuration on the centerline of the wellbore, to accommodate the coring line, which retrieves the coring tools from the drill string. The crown is equipped with seven, 66-in. diameter sheaves grooved for 1 _-in. wire rope. Also on the crown are four, 20-in. diameter sheaves grooved for _-in. wire rope to handle the coring line used to retrieve cores. There are two coring lines, each requiring two sheaves.

3. Traveling Block The traveling block (Fig. 2) is a Dreco split block rated at 1,200,000 lb designed and built to API Spec 8A. The split design of the block allows for an 8-in. opening to extract core- retrieving tools from the drill string. The block is equipped with six 66-in. diameter sheaves grooved for 1_-in. wire rope.

4. Drill String Compensator a. The Passive Heave Compensator (PHC) and Hook (Fig. 2) are connected to the Dreco traveling block. The PHC is a Western Gear Model 800-17-20 compensator, which has a hoisting capacity of 800,000 lb open in the compensating mode and 1,200,000 lb in the closed and locked position. The total stroke of the PHC is 20 ft. Below the PHC

is a National J-600 hook. The PHC and hook is designed with a 5-in. bore through the middle to allow removal of the coring tools from the drill string. The PHC uses two 4-in. air hoses and one control umbilical. b. The Active Heave Compensator (AHC)(Fig. 2) is connected to the inline Western Gear PHC on the JOIDES Resolution and is a Maritime Hydraulic Active Heave Compensator. Its purpose is to isolate the drill string from the motion of the drillship. The AHC is on-line during coring operations. For additional information, go to the AHC tool sheet located at: http://www-odp.tamu.edu/publications/tnotes/tn31/ahc/ ahc.htm.

The main components of the AHC system are: • Two active heave cylinders with servo valve block and accumulator mounted on the PHC. • Electrical control cubicle • Driller control panel • Hydraulic power unit with starter panel • Motion reference unit

The AHC uses two umbilicals: one for controls with two cables and one for hydraulics with four hoses.

5. Hook Below the PHC is a National J-600 hook (Fig. 2). It is rated at 1,200,000 lb. The hook is designed with a 5-in. bore through the middle to allow removal of the core retrieving tools from the drill string.

6. Top Drive The top drive (Fig. 2) is a Varco Model TDS3 equipped with an EMD M89 1000-hp motor rated for 30,000 ft-lb of torque at 169 rpm continuous. The top drive has a lifting capacity of 1,000,000 lb. It is supplied with hydraulic power to tilt the top drive for mousehole connections and to swing the top drive and swivel out of the way for trips. The top drive is equipped with two umbilicals: one for power and one for controls. ODP operates with a second top drive in inventory on the ship for back up.

7. Swivel, Wireline BOP, and Oil Saver The swivel mounted on top of the top drive is a National Model P650 Special Swivel. The swivel has a load capacity of 1,300,000-lb static and 904,000-lb rotating. The gooseneck on the swivel is designed with a flange on top for mounting a valve, wireline blowout preventer, and an oil saver. This design allows for insertion and removal of the core retrieving tools and the use of the Coring Wireline while circulating the hole. The derrick is equipped with one mud supply hose.

8. Coring Wireline Winch Located on top of the drill floor roof is a National independent double drum-coring winch specially designed for ocean coring operations. A single D79 750-hp motor powers the

9. Iron Roughneck-Drill Floor The drill floor is equipped with a Varco Model IR2100 iron roughneck (Fig. 3). The spinner adjusts from 3_ in. to 8_ in. The wrench will produce a maximum make-up torque of 63,000 ft-lb and a maximum break out torque of 75,000 ft-lb.

10. Horizontal Pipe Racker The drill pipe is stored in three semi-automatic horizontal drill pipe rackers (Fig. 3). The 5-in. drill pipe is stored in two Western Gear Pipemaster Piperackers. Each pipe rack will hold 130 stands of 5-in. drill pipe. The 5_-in. drill pipe is stored in a Victoria Machine Works pipe racker that will hold 104 stands of 5_-in. drill pipe. The pipe racker is equipped with a skate, an automatic pipe stabber, a riser crane, and remote controls.

11. Dual Elevator System Forward of the rotary table is a Varco DEHS/471 dual elevator handler (Fig. 3). The dual elevator handler has a horizontal reach of 60 in. and a vertical reach of 36 in. It has the capacity to move 350- or 500-ton elevators. The stool sits in the rotary table and is used to support the weight of the drill string during trips or connections or a drive-off from location. Opening a door and lifting it out of the rotary table removes the stool from around the drill string. The dual elevator system is utilized to eliminate damage to the drill string from slips.

12. Drawworks The drawworks (Fig. 3) is an Oilwell E-3000 electric drawworks. The power for the drawworks is supplied by two EMD D-89-MB 1000-hp electric motors. The drum of the drawworks is 36 in. x 62 in. with Lebus grooving for 1_ in. wire rope. The auxiliary brakes on the drawworks consist of two Elmagco Model 7838 electric brakes. Mounted on the catshaft of the drawworks is a sand reel with the capacity of 24,690 ft of 9/16-in. wire rope.

TRIPPING SPEED ANALYSIS OF THE ODP DERRICK SYSTEM

Legs 201 and Leg 204 were used to determine the tripping capability of the Ocean Drilling Program derrick system. During Leg 201, the maximum drilling depth was ~5100 meters below rig floor (mbrf), and during Leg 204, drilling occurred in shallow waters varying from 900 mbrf to 1000 mbrf. All plots for Legs 201 and Leg 204 are shown for trip-out data, as trip-in data were not available.

Trip Out Deep Water (WD = 5089.5 m; Fig. 1) A typical hole from Leg 201 (Hole 1230E) was selected to determine the tripping speed. The seafloor depth was 5098.5 mbrf and total depth (TD) was 5134.5 mbrf. Two different sections of the trip out are shown in Figure 1. The first section was measured while the pipe was tripped out in triples with the top drive set back in the derrick. The second section was measured when the bottom-hole assembly (BHA) was laid out.

After setting back the top drive and starting to pull out of the hole with triple stands, the crew was tripping at a rate of 17 m/min. initially. Over the majority of the time spent tripping out of the hole, the average trip speed was 35 m/min. For the last 21 stands, the trip speed rose from 35 m/min to 65 m/min. The falling speed of the empty blocks was between 80 to 95 m/min. throughout the trip plotted in Figure 1.

Trip Out Shallow Water (WD = 907 m; Fig. 2) A second hole from Leg 204 (Hole 1244B) was selected for comparison with the tripping speed from Hole 1230E. The seafloor depth was much shallower (907 mbrf) and TD was 961 mbrf. The first half (1910-2000 hr) of Figure 2 displays the block position and trip speed of the pipe trip using the top drive while pulling alternating single and double stands of pipe. The second half (2020-2120 hr) of Figure 2 shows the change in block position and tripping speed while tripping triple stands with the top drive set back.

Prior to setting back the top drive to allow continued rotation and circulation in the open hole, the crew pulled the pipe out by: 1. breaking out a single and setting it in the mouse hole, 2. breaking out a double and making it up to the single, and 3. then laying the triple out with an air tugger in the rack.

Handling a single, the trip speed averaged 15 m/min. with a falling speed for the empty blocks of 25-30 m/min. Handling a double, the trip speed averaged 25-30 m/min. with an empty block falling speed of 45-60 m/min.

After setting back the top drive and starting to pull out with triples, the tripping speed increased from 50 m/hr to 75 m/hr. The falling speed of the empty blocks was 110 m/min. throughout the trip.
