1. Scope:

The intention of this specification is safely dock and undock the CCGS Hudson allowing access to the underwater hull section of the vessel and facilitate the work package included in this document.

2. Technical Description:

2.1 General

2.1.1 The vessel shall NOT be docked with any other ship for any part of the contract period in such a way that will interfere with its scheduled re-floating.

2.1.2 A docking plan shall be provided to the successful Contractor if required. The vessel's principal particulars are as follows:

VESSEL PARTICULARS Length, Overall 90.4 m Length, Between Perpendiculars 80.8 m Breadth, Moulded 15.4 m Depth, Moulded 9.1 m Mean Draft, Extreme 6.3 m Displacement, Light Op’s Arrival 3766.55 L. Tons Displacement, Extreme 4773 L. Tons

It is estimated that the drafts will be 6 meters aft and 5.7 meters fwd. at the time of docking

2.1.3 Contractor shall prepare blocks and necessary shoring to maintain true alignment of the vessel’s hull and machinery throughout the work period.

2.1.4 The vessel shall be docked so that all docking plugs, transducers, anodes and sea inlet grids are clear and accessible. Contractor’s Docking Master shall note the position of the transducers and drain plugs as noted on the Docking Plan drawing provided in order to avoid these from coming in contact with the keel and/or bilge blocks. If any hull fittings are covered, Contractor shall be responsible for all labour and materials required for making corrective arrangements to drain tanks or move blocks to gain access to areas of specified work.

SPECIFICATION NO. 16-H011-015-1 Page 33 CCGS Hudson Dry-docking Spec 2016/17

2.1.5 The Contractor shall be responsible for the safe transfer of the ship during all movements between berthing locations and docking blocks. During docking and undocking of the ship, radio contact is to be maintained between the vessel's Commanding Officer and the Contractor's Docking Master. Contractor shall include in their pricing the cost of any tug and/or pilot services required to safely complete this requirement.

2.1.6 Tank Soundings

(a) Prior to docking, the contractor shall complete sounding on all tanks. These sounding shall be witnessed by CGTA and the results recorded. (b) Prior to undocking all fuel tanks will be returned to the same levels as at the time of the original docking. When this has been completed, the tanks shall be sounded and recorded.

HD-36 Fwd. Cargo Hold trunk inserts 1. Scope:

The Intent of this specification is to repair by insert method the wasted steel that has been found in the hatch coaming for the flush mount main cargo hatch.

2. Technical Description:

2.1 General

2.1.1 A perforation has occurred in the steel trunking of the flush mount main cargo hatch in the port aft section. The perforation is currently patched with Epoxy steel.

2.1.2 The hatch trunk between the Main Deck and the Upper Deck, between frames 169 and 176 ½ is formed of full height tween deck bulkheads, stiffened by half round bars. At the top ends of these bulkheads, structure is fitted in order to support the hatch cover and to form a seal for it when it is in the closed position. It is the area of the bulkheads immediately above the location of this existing hatch support structure that is the subject of this specification section.

2.1.3 Ultrasonic testing has been carried out on the top section of these trunk bulkheads, and has shown up several locations of excessive corrosion that need to be addressed. These locations are shown on the accompanying guidance Drawing No. J16017-S15 and are as follows:

2.1.4 On the Port Side of the Hatch at the bulkhead located between frames 169-176 ½ there is an area of excessive corrosion towards the aft end of the bulkhead, with several spots where ultrasonic testing has highlighted excessive corrosion.

SPECIFICATION NO. 16-H011-015-1 Page 200 CCGS Hudson Dry-docking Spec 2016/17

2.1.9 Centerline Non-Watertight Bulkhead. There are areas of corrosion present at various locations throughout the Aft Trim Tank, which runs from frame 0 to frame 13, and extends from the plating forming the ship’s bottom to the underside of the Main Deck.

2.1.10 Between frame 0 and frame 9, the centreline non-watertight longitudinal bulkhead is corroded and in need of replacement. The bulkhead is flanged 3” top and bottom, and is welded to the existing structure, such that it sits on top of the transverse deep beams extending the width of the tank. At the top, the flanged bulkhead plating is welded to the flange of the transverse deck beams, and the new replacement bulkhead plating is to be attached in the same way. The bulkhead is to be fitted in two pieces, one from frame 0 to frame 5, and the other from frame 5 to frame 9. The Contractor shall bid on an insert size of 70” wide X 80” long for frames 0 to 5 and an insert 60”wide X 90” long for frames 5-9. See Lengkeek guidance drawing J16017-S17 Rev0 Sheet 5 of 5 for details.

2.1.11 The new non-watertight bulkhead plating is to be of 5/16” plate thickness, and is to include a similar combination of 18” x 15” and 21” x 15” access openings, templated from the openings in the existing bulkhead, and cut at the same locations. Cut outs are to be made in the new longitudinal bulkhead plating to enable it to fit over the new transverse channel struts at frames 3, 5 and 7. See Lengkeek guidance drawing J16017-S17 Rev0 Sheet 5 of 5 for details.

2.1.12 The three (3) existing vertical angle bar stiffeners on the non-watertight centreline bulkhead are to be replaced, between the underside of the main deck and where they are overlapped and welded to the existing structure below the non-watertight bulkhead, at approx. 16’-0” above baseline. The stiffeners are 3 1/2”x3”x5/16” angle bars, and are to be welded with intermittent spacing similar to the original bulkhead stiffeners. Two (2) stiffeners length to be 98” long and one (1) stiffener 90” long. See Lengkeek guidance drawing J16017-S17 Rev0 Sheet 5 of 5 for details.

2.1.13 Transverse Bulkhead Frame #9: The transverse bulkhead forming the forward end of the tank at frame 9 has excessive corrosion and requires replacement. The top plate (starboard) extending approx. 3’-9’ down from the underside of the main deck.

2.1.14 The top half of the bulkhead lower plate (port and stbd), extending 1’-6” down from the existing transverse plate seam and the bottom edge of the new top plate (starboard) as described above. The thickness of the replacement bulkhead plating is to be 5/16”

2.1.15 Several of the bulkhead stiffeners also require replacement due to excessive corrosion. At the port side, the fourth and fifth stiffeners outboard from the centreline need to be cut out for their full length and replaced with new 3”x3”x5/16” angle bars. At the starboard side, the fourth stiffener outboard from the centreline only needs to be cut out and replaced with a new 3”x3”x5/16” angle bar. The remainder of the existing bulkhead stiffeners are considered suitable to be left in place. These will need to be rewelded to the new bulkhead plating as described above once it has been fitted in place. See Lengkeek guidance drawing J16017-S17 Rev0 Sheet 4 of 5 for details.

2.1.16 Deck Transverse Beam on the underside of the Main Deck: Three (3) of the deck transverses within the Trim Tank at the underside of the main deck are heavily corroded and require replacement. The

SPECIFICATION NO. 16-H011-015-1 Page 201 CCGS Hudson Dry-docking Spec 2016/17

corrosion has occurred at the transverses at both port and starboard sides, at frames 2, 4 and 6. The replacement deck transverses are to be the same scantling as the existing (assumed 6”x3 ½”x3/8” angle bars) oriented to toe forwards similar to the existing deck beams.

2.1.17 The plate brackets at the outboard ends of the deck transverses, that connect them to the side shell stiffeners, can be rewelded to the new side shell stiffeners and the new deck transverse beams; if found to be necessary, new plate brackets can be fabricated and welded in place. See Lengkeek guidance drawing J16017-S17 Rev0 Sheet 2 of 5 for details.

2.1.18 Side Shell Stiffeners: The side shell stiffeners throughout the trim tank are composed of tee sections of 9 ¾”x 6 ¼”x ½” scantling, which are cut from an S20x66 beam. These stiffeners have suffered from excessive corrosion. They extend from the point where they are overlapped and welded to the existing floors on the centreline of the tank, to above the main deck, where they taper to attach to existing side shell stiffeners above. As the side shell stiffeners are replaced, the 5/16” plate brackets connecting them to the underside of the new side shell longitudinal stringers shall also be replaced.

2.1.19 All of the side shell stiffeners are to be replaced at frames 1 through 8, port and starboard. See Lengkeek guidance drawing J16017-S17 Rev0 Sheet 2 of 5 for details.

2.1.20 The existing plate brackets at the underside of the ends of the main deck transverse beams can be trimmed and rewelded to the new side shell stiffeners once they are in place.

2.1.21 Transverse Open Floors: Several of the transverse floors throughout the trim tank are substantially corroded, and require replacement. The floors are of 5/8” plate and are flanged 3” at the top, where they are attached to the side shell stiffeners. The depths of the floors varies throughout, but due to the narrow shape of the tank at the bottom, the extent of the floor requiring replacement is considered as extending to the uppermost transverse weld seam. The following floors shall be replaced:

I Frame 1- Port Only II Frame 2- Port and Starboard III Frame 3- Port and Starboard IV Frame 4- Port and Starboard V Frame 5- Port and Starboard VI Frame 6- Port and Starboard VII Frame 7- Port and Starboard VIII Frame 8- Port and Starboard

2.1.22 Struts: The aft trim tank has three (3) transverse struts across the width of the tank, at frames 3, 5 and 7, formed from MC8 x 22 channel bars. These have suffered from corrosion and require replacement. The existing channels shall be cut free and used as templates to cut out new replacement struts, with the same tapers and end cut outs as per existing ones. The struts pass through the centerline bulkhead, through the existing cutouts. These shall be welded on to the back sides of the new 3 ½”

SPECIFICATION NO. 16-H011-015-1 Page 202 CCGS Hudson Dry-docking Spec 2016/17

x3”x5/16” vertical angle bar bulkhead stiffeners. See Lengkeek guidance drawing J16017-S17 Rev0 Sheet 1 of 5 and drawing J16017-S17 Rev0 Sheet 3 of 5 for details.

2.1.23 At their outboard ends, the channel struts shall be welded to the new longitudinal side shell stringers with new flanged plate brackets formed from 3/8” plate.

2.1.24 Side Shell Stringers: There is a side shell stringer running the full length of the trim tank below the main deck port and starboard, and these stringers are to be cut out and replaced. The stringers consist of a 30” deep x 1/2” thick web plate, with a 6” x ¾” thick face bar on the inboard edge of the web. These stringers are bracketed to the side shell stiffeners with 7/16” thick plate brackets; the brackets also need to be cut out and replaced with new steel.

2.1.25 The existing stringer has cut outs to enable it to fit over the existing side shell stiffeners. The web plates of the new stringers need to be similarly cut out to fit over the new and existing side shell stiffeners (see appropriate section of this repair specification.) The existing stringers can be utilised as a template to cut the stiffener openings for the new stringers. See Lengkeek guidance drawing J16017- S17 Rev0 Sheet 1 of 5 for details

2.1.26 The Contractor shall adhere to “CCGS Hudson Welding Inspection and Test Plan Revision 1”. The Contractor shall use the Welding Test and Inspection plan as laid out in the CCG Welding Specification Section 5.6 and the Welding guide Section 3 and section 4

HD- 40 – Tank Vent Head Replacements (SURVEY)

1. Scope:

1.1 The existing gooseneck vents are in an advanced state of corrosion due to the age of the vessel. It is no longer feasible to keep these units in a good state of repair. The intent of this spec is to remove the existing goose neck style vents and retrofit new WINTEB units. There are 67 vent heads in total that must be modified to attach a WINTEB 2000 HIAS (W2HIAS) style head. These heads will be GSM and will be suited for either a typical ANSI CL 150LBS flange connection or will be suited for a small flange fit, which is a custom vent head style from WINTEB.

1.2 All vents have been noted on Flag State Inspection Report dated 9 September 2016. Therefore, Contractor shall communicate with Lloyds Inspection service to coordinate any inspection objectives that the Class inspector may have for this scope of work.

2. Technical Description:

2.1 General
