3.1 General.

15 (Rev-0)

3.1.1 CIR. The Contractor shall submit a CIR for the inspections listed in the following paragraph(s):

3.2.3 Post-surface preparation cleaning and inspection.

3.1.2 Tech Rep. The Contractor shall refer to SFLC Std Spec 0000, paragraphs 3.2.4.2.1 (Painting contractor certification program requirement) and 3.2.4.2.2 (Coating Tech Rep), for applicable requirements.

3.1.3 Protective measures. The Contractor shall furnish and install all protective coverings to seal off and protect all non-affected vessel's components, equipment, and spaces near the work area against contamination during the performance of work. Upon completion of work, the Contractor shall remove all installed protective measures, inspect for the presence of contamination, and return all contaminated equipment, components, and spaces to original condition of cleanliness. 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.

Sea valve openings.

Propeller shaft bearings and seals.

Rudder bearings.

Propellers.

Zinc anodes (unless anodes are being renewed).

3.1.4 Interferences. The Contractor shall 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.

NOTE

The hull fairings are not to be removed simply as an interference for 100% near white blasting unless found to be failing.

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.

3.1.5.1 Fairing inspection. Prior to preservation preparation, inspect hull fairing condition. 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.

16 (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) Body and Boot-Top (U/W Body and Boot-Top, Steel Hulls (Up to 7 Years), in Salt Water”, in SFLC Std Spec

6310, Appendix A (Cutter and Boat Exterior Painting Systems). Ensure that the anticorrosive (AC) is tacky prior to applying the first antifouling (AF) top-coat.

3.2.2.2 Ensure that the first AF coat is applied over the AC undercoating, while it is still tacky.

3.2.3 Post-surface preparation cleaning and inspection. After completion of surface preparation and prior to coating application, accomplish the following tasks and submit a CIR.

3.2.3.1 Perform a visual inspection of the prepared U/W body steel substrate.

3.2.3.2 Perform solvent cleaning of all prepared surfaces, in accordance with SSPC-SP 1. Capture, contain, and dispose of all wastes from solvent cleaning, in accordance with all Federal, state and local regulations.

NOTE

Lists of all authorized coating materials and suppliers are listed in SFLC Std

Spec 6310, Appendix C (Cutter and Boat Authorized Coatings).

3.2.3.2 Ensure the alternating color coats shall be as follows: Red/Grey/Black/Red/Black. The first two coats are anti-corrosive and the final three coats are anti-foulant in accordance with SFLC Std Spec 6310.

The first four coats are applied to both U/W body and boot-top. The final black AF coat is for boot-top only.

17 (Rev-0)

3.3 Draft mark painting. The Contractor shall paint all draft marks with two coats of a “Polysiloxane” or

“Silicone Alkyd Enamel” coating, at 2.0-3.0 mils DFT, white (17925).

3.4 In-process quality control measures. The Contractor shall abide by all the safety, preservation, and quality control requirements specified in SFLC Std Spec 0000, paragraph 3.2.4.2 (In-process QC measures for “critical-coated surfaces). Surfaces being preserved are considered “critical-coated surfaces”.

3.5 AF system protective measures – in the event of prolonged atmospheric exposure. If the vessel will not be refloated within the immersion time as recommended by the coating system manufacturer, the

Contractor shall employ suitable measures - including but not limited to keeping the coating system wet and away from direct sun light, to avoid film damage that may reduce or impact the final performance of the AF coating system when placed into service.

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 upper edge of the boot-topping, as shown on Coast Guard Drawing 627 WMEC 601-001, including rudders, transducer hull rings, sea chests (including the sea chest inlet up to the final connection with the flange face at the sea chest isolation valve(s)), bilge keels, struts, skegs, gratings, rope guards, and all other appendages.
