· Fathometer transducer surfaces.

· Sea valve openings.

· Propeller shaft bearings and seals.

· Rudder bearings.

· Propellers.

NOTE

Zince anodes are being renewed and do not have to be protected.

3.1.4 Interferences. The Contractor must handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences). Known interferences include, but are not limited to the following:

· Sea chest grating.

3.1.5 Initial inspection. Prior to removing the existing coating system, the Contractor must inspect and verify whether all draft marks have permanent markings (weld beads or impressions), showing their location on the hull. Submit a CFR.

3.1.6 Water used in preparation and washing procedures. The Contractor must ensure that water used in all surface preparation tasks, including pre-surface preparation wash and water jetting, is of sufficient purity and quality that it does not prevent the surface being cleaned from achieving the required degree of surface cleanliness or non-visible contamination criteria.

3.1.6.1 Ensure that surface preparation water does not contain sediments or other impurities that are destructive to the proper functioning of the cleaning equipment.

3.1.6.2 Ensure that all water used in any surface preparation or cleaning procedures is captured, contained, and all spent water disposed of in accordance with all Federal, state and local regulations.

3.1.7 Surface preparation optional methods. The Contractor has the option of using either high/ultrahigh pressure water jetting or abrasive blasting to achieve the required surface preparation, prior to application of the coating system specified in 3.2 (Preservation requirements). The Contractor may add abrasives to the water jet stream, for one or both of the following reasons:

· Achieving greater productivity.

· Achieving the required surface profile.

NOTES

1. Existing coating system on the U/W body surfaces may have a nominal thickness in excess of that which was originally installed, because of “patch-coats” applied during past drydock availabilities.

2. Water jetting without abrasive addition does not provide any additional anchor profile to the surface, beyond what was present after the previous surface preparation.

3. Whenever fleeting is required for any reason, if the U/W Body has not yet been fully preserved, the areas adjacent to all docking blocks must be fully preserved at least 2 feet in each direction prior to refloating the vessel. If the vessel will be placed onto a different blocking position, the areas in way of the new blocking position must be fully preserved.

3.2 Preservation requirements. The Contractor must accomplish the following tasks:

3.2.1 Pre-surface preparation wash. Accomplish low-pressure (less than 5,000 psi) freshwater wash of all affected surfaces, to remove soluble chlorides and other surface contaminants. Refer to SSPC-SP 1, for guidance.

3.2.2 Surface preparation and coating application.

The Contractor must accomplish the following tasks:

3.2.2.1 The Contractor must prepare and coat the U/W hull surfaces with the system specified for “Underwater (U/W) Body and Boot-Top (U/W Body and Boot-Top, Icebreaker <235’, in Salt Water)”, in SFLC STD SPEC 6310, Appendix A (Cutter and Boat Exterior Painting Systems(.

3.2.2.2 The Contractor must coordinate U/W Body preservation with side scan/ultrasonic testing if side scan work item is included in availability. If included, the following paragraphs must be applicable:

3.2.2.2.1 The contractor may elect to apply the anti-abrasion icebreaking coating in two coats rather than one to facilitate side scan procedure if approved by the COR. If selecting this option, the contractor must provide a written statement from the coating manufacturer approving the application of the icebreaking coating in two coats to the COR for approval during the Arrival Conference. Include details of incorporation of side scan procedure in the “Preservation Plan,” required by SFLC Std Spec 6310, paragraph 3.2.

3.2.2.2.2 If the two-coat option is approved by the COR, the side scan must be performed over first coat. Second coat application must follow completion of side scan. Total DFT of both coats must meet listed DFT of single coat anti-abrasion icebreaker DFT in SFLC Std Spec 6310, Appendix A. Application of coats must be in accordance with manufacturer’s overcoating intervals.

3.2.2.3 Ensure that the first AF coat is applied over the AC…
