1. DESCRIPTION

1.1 Vessel general The fully diesel electric, dynamically positioned (DP3) crane approx. 13000mt (approx. 10000mt after the S-lay System is vessel is equipped with a 5000mt Huisman Offshore Mast installed). Crane (OMC) and optionally a 600mt S-lay System. The crane and vessel are capable of fully revolving with 5000mt load. The vessel design is based on a variable draft concept. At The vessel is optimized for long transits at high speed up the transit draft the breadth of the vessel is limited which to 15 knots. The vessel is suitable for operating world-wide allows sailing at high speed and good motion characteristics including the following areas: China, Brazil, , in waves. The pipe-laying operations and light lifts can be West of Africa, the , etc. also performed at this draft. For heavy lifts the vessel draft is increased. This increases the breadth of the water line in order The crane vessel is designed for multipurpose hoist- and- to provide sufficient stability for heavy lift operations. Special subsea lifts and pipe-laying operations. The design is attention is given to the DP system to achieve a high DP developed in such a way that the 600mt S-lay System can performance for work offshore. A dedicated fast anti-heeling be installed later on the main deck with limited effort. A system is utilized in order to compensate the heel angle when large deck space allows transporting a variety of modules, the crane revolves. A 10 point mooring system is foreseen for handling equipment or can be used for pipe storage when operations in shallow waters. performing pipe-laying operations. The available deck load is

1.3 600mt S-lay system The pipe handling system consists of a supply line which handles single and double joints to supply the firing line, located on the port side of the vessel. A pipe kick out line to transport the pipe out of the firing line, in case the pipe has to be cut back is located on starboard. The pipe sections are stored in cradles on the main deck or supplied by a vessel or . The pipes are placed on the port landing unit (or optionally on the starboard landing unit) by the pipe handling cranes. The landing unit is a bumper frame to facilitate pipe landing and to prevent damage to the conveyor rollers. The pipe sections are transported to a transverse conveyor using conveyor rollers. This transverse conveyor takes the pipe through the beveling area, which is shielded from bead stall stations are available in front of the tensioners and one in area and the firing line to limit noise and clutter. The beveled between the tensioners for welding singles. When processing pipe section is then transported on conveyor rollers onto a double joints three welding stations are available in front second transverse conveyor which transports the pipe to the of the tensioners. The welding stations are followed by an firing line. This transverse conveyor is equipped with several NDT station in between the tensioners and two (one in case working positions for pre-heat etc. of doubles) coating areas aft of the tensioners. The sea- going pipe is supported by the firing line roller boxes located between the workstations. All workstations except for the coating areas are equipped with trolleys that can engage the sea-going pipe to eliminate relative movement. The trolleys are able to follow the movement of the pipe. The tensioners are mounted on rails, this makes the handling and installation of large inline structures more efficient. The tensioners can be fully opened and skid out of the way to allow passage of large structures while the other two tensioners the sea-going pipe.

The pipe tension is divided over three 200mt tensioners spaced apart to allow workstations in between. The tensioners are equipped with a squeeze equalizing system to allow laying of concrete coated pipe, as an additional feature this system can also be used when laying non concrete coated pipe, to facilitate passage of e.g. anodes.

The 600mt A&R system consists of a storage/traction winch combination with a wire that is routed to the firing line via a retractable sheave box. The sheave box can be rotated in or The firing line receives pipes from the port supply line. The out the firing line using a hydraulic cylinder. The secondary A&R pipe joints are loaded from the transverse conveyor onto the system consists of a 200mt winch and two guide sheaves, this lineup table using transverse transport carts. The lineup table system is used when the tension is relatively low. Because the consists of two line up tools that are electronically coupled capacity of the secondary A&R system is lower the system is and act as one single line up table (all three line up tools are easier to operate, and uses a more economical wire. used when using double joints). A maximum of five welding

The stinger of approx. 95m in length is another major part of the S-lay system. The stinger consists of 3 segments and it can be adjusted for a large range of radii depending on the water depth and the pipe diameter. The stinger is connected to the stern of the vessel and it is suspended from the stinger handling frame. In transit the stinger and the handling frame can be disconnected from the stern of the vessel and these can be put on the deck using main 5000mt crane.

1.4 Design Options The vessel will initially be equipped with 5000mt crane only. The 600mt S-lay can be installed later when required.

The crane stowing position is to the starboard with the boom rest close to the side of the vessel. This keeps a large deck area free from any obstacles allowing to carry construction works or transport of large objects in an efficient way. The crane stowing position becomes at the center line above the firing line. The existing boom rest is simply moved from its When required the S-lay equipment is installed on the main original position to the top of the firing line to maximize space deck with the firing line tunnel at the center line of the vessel. for pipe handling cranes.

1.5 Variable draft concept The variable draft concept allows to control the vessel motions for a wide range of operational conditions. At light draft (when no heavy lifts are performed) the breadth at the water line is limited and the stability parameters of the vessel are close to its optimum. At larger drafts corresponding to heave lift conditions the breadth increases, keeping the stability parameters close to the optimum. This makes it possible to keep the natural roll period of the vessel beyond (longer than) the periods of existing waves for virtually all operating conditions. This significantly reduces roll motions as shown in the plot below. An extensive model test program was carried out in order to verify the concept and provide accurate measurements of motion response and resistance.

1.6 Anti-heeling systems A dedicated anti-heeling system is applied in order to compensate for the heel moment caused by the crane. This system utilizes large water ballast tanks connected by cross- overs for pumping large amount of ballast water when the crane is performing heavy lifts.

Optionally an additional anti-heeling system can be installed. This secondary fast system is designed to compensate for heel angle when the crane slews empty or with small loads. This system consists of two masses moving in transvers direction. These masses are located below main deck. The speed of this automatic system matches the slew speed of the crane, which make operating the crane highly convenient. engaged when extra power is required for instance during 1.7 Accommodation offshore lifts operating using DP. 398 persons are accommodated in single, twin, and four person cabins. Further the accommodation is outfitted with The vessel is equipped with seven thrusters. In the aft of offices, change room and laundry facilities, mess room, the vessel three azimuthing thrusters and a retractable galley and provision stores, hospital, recreation areas, and a azimuthing thruster are located.
