Services identified with an asterisk (*) will be required both in dry dock and at the contractor's dock.

2.2 (*) Provide workers and services for installing and removing two gangways, handling the mooring lines and installing a protective net under the gangways during the dry dock period. The gangways will be provided by the shipyard.

2.3 (*) Supply to the ship a phone line (including the telephone) and a high speed internet connexion (including the cable). The phone and internet services will be operational 24 hours a day, ensuring communications at all time. These services will be maintained for the whole dry dock duration.

SECTION H.D.-3 INSPECTION COMMENTS EXTRA REPAIRS

3.1 The work must be performed and inspected to the complete satisfaction of the Fisheries and Oceans/Coast Guard (CG) representative and that of Transport Canada Marine Safety (TCMS) 3.2 The representatives must be notified when each item in these specifications has been completed so that they can inspect the work before the final steps for each item are carried out.

3.3 Inspection of any item by the Coast Guard does not eliminate the need for inspection by the (TCMS).

3.4 The contractor will also be responsible for communicating with the (TCMS)inspectors in order to plan in advance the inspections required for each task.

3.5 The contractor must provide to the Coast Guard representative four (4) complete reports on all measurements and readings taken during the refit.

3.6 All extra work not described in these refit specifications and resulting from the inspection must be negotiated by the PWGSC representative using form 1379.

DFO – CG\ITS IN, Refits Page 8 CCGS DES GROSEILLIERS – MAY 2014

SECTION H.D.-5 BLOCKS COMMENTS

5.1 Reference: Drawing number 68-H-105, Docking plan

5.2 The blocks that support the keel and hull but that also block removal of the drain plugs from the tanks will have to be moved, as well as those preventing access to the freshwater intake screens and sea chests. Do not place transducers of acoustic sensors on the blocks between frames 138 and 140, port and starboard, nor the Doppler sonar transducer between frames 155 and 156.

5.3 Since the shipyard will have access to a docking plan (plan d'attinage) as soon as the contract is granted, the movement of mispositioned blocks (refer to section 5.2 of these specifications for proper positioning) will be done at the shipyard's expense.

5.4 If the Coast Guard requires these blocks to be moved for other reasons, the contractor must list a unit price (i.e. the cost per move) in an annex.

DFO – CG\ITS IN, Refits Page 9 CCGS DES GROSEILLIERS – MAY 2014

SECTION H.D.-6 PROPELLER COMMENTS

6.1 Remove and replace the starboard propeller.

6.2 Remove the shaft guard to measure the wear down of the starboard shaft and check that they are concentric. These measurements will be taken in the presence of the chief engineer with instruments provided by the shipyard, and recorded to be given to the surveyor. The equipment to check the concentricity of the shaft will also be provided by the shipyard. Note: Take the necessary precautions to permit the reuse of the shaft guard.

6.3 After removing the cement, unbolt and remove the propeller cap and place it at the end of the dry dock.

6.4 Unbolt and remove the brake pad from the Pilgrim nut. Then completely unscrew the nuts from the shafts and screw them back in, taking care to turn them around, i.e. positioning them such that the inner moving part of the nut is on the outside rather than facing towards the propeller hub. The ring and the rubber seal on the inside (i.e. on the same side as the stern tubes of the propeller hub) must also be removed.

6.5 Then install the eight (8) special bolts (provided by the ship) in the propeller hub. Slide the special plate 6 inches thick and 4 feet in diameter onto these bolts. This will be kept against the Pilgrim nut and the propeller shaft with 8 nuts.

SECTION H.D.-6 PROPELLER COMMENTS

(Continued, 6.5) The eight (8) nuts will hold the special plate in place against the Pilgrim nut. After applying pressure with the hydraulic pump (provided by the ship), the propeller will be loosened on the cone of the propeller shaft. The propeller will be held up with a hoist during this procedure. Installation of lifting eyes is necessary and at the Contractor's expense, this Includes the removal of lifting eyes at the end of the work.)

6.6 The propeller will then be taken out of the cone-shaped portion of the shaft. It will be loaded into a truck and sent to the Coast Guard in City (cost covered by shipyard).

6.7 The starboard propeller provided by the CG will be adjusted and put back in its place. The contractor must include eight (8) adjustments in the Prussian blue. The propeller adjustments will be made on site. The contractor must also list a separate price in the event that extra adjustments are needed.

6.8 Finally, the propeller will be repositioned. Make sure to install a new rubber joint (provided by the shipyard) on the inner surface of the hub. The propeller will be tightened back onto the conical portion of the shaft using the Pilgrim nut and the hydraulic pump. Once the propeller is properly in place, the nut will be tightened and locked. After cleaning the propeller cone, reposition it and refill the inside with tallow, then fill the outer cone nut holes with aluminous cement.

SECTION H.D.-6 PROPELLER COMMENTS

6.9 Construct, shape and weld in place shaft guards using ¾-inch thick steel (provided by the contractor). The shaft guards must be welded continuously along their entire circumference; joints between half-sections must also be welded. The cost of manufacturing the shaft guards will have to be included; this price must be listed in an annex, to be counted as credit if they do not need to be replaced.

The shaft guards will first need to be cleaned by sandblasting to S.A. 2 1/2 and then painted on both sides with Intershield 163/Inerta 160 Black.

NOTE: All special tools and equipment used for this work must be returned to the ship. The roundtrip handling and cleaning are the responsibility of the contractor. During the removal and re- installation of the propellers, the chief engineer or his representative must be present. Once the propeller has been removed, the Pilgrim nut will be reinstalled on the propeller shaft.
