Specific areas/equipment/components to be protected include, but are not limited to:

All scuppers and overboard discharges.

Waterline area where U/W body coating system interfaces with freeboard coating system (unless freeboard surfaces are also being preserved).

Fathometer transducer surfaces.

3.1.5 Initial inspection. Prior to removing the existing coating system, the Contractor shall 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 shall 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.

22 (Rev-0)

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.

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

3.2.1 Pre-surface preparation wash. Accomplish low-pressure (less than 5,000 psi) fresh water 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 shall accomplish the following tasks:

3.2.2.1 Prepare and coat the U/W hull surfaces with the system specified for “Underwater (U/W)

QC measures for “critical-coated surfaces). Surfaces being preserved are considered “critical-coated surfaces”.

3.5 AF system protective measures. The Contractor shall employ coating system manufacturer’s recommendations to prevent AF coating damage if immersion time requirements are not met.

4. NOTES

4.1 Definitions.

4.1.1 U/W Body. The underwater body is defined as the areas from the bottom of the keel to the waterline, as shown on Coast Guard Drawing 49A BUSL 601-003, including rudders, transducer hull rings, keel coolers, bilge keels, struts, skegs, gratings, and rope guards.
