Not applicable.

12 (Rev-0)

3.1.2 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.

3.1.3 Interferences. The Contractor shall handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences).

3.2 Visual Survey. Following the guidance in CG Dwg 378 FRAM W 801-1 and CG Dwg 378 FRAM W 602-100, identify the markings to be removed from the cutter. These marking include: US Coast Guard Emblem (decal) on the port and starboard sides of the hull, US Coast Guard Emblem on the port and starboard sides of the superstructure (See Detail Elevation 11-E)), diagonal striping on the port and starboard sides of the hull, ship’s name on the stern; ship’s hull number on the port and starboard bow, ship’s hull number on the port and starboard sides of the stern, and the words “U.S. COAST GUARD” on the port and starboard sides of the hull. Draft markings will remain on the vessel.

3.2.1 The Contractor shall supply and install all tarping and masking as required to keep paint chips and sanding debris from getting into water surrounding the vessel. Provide a barge or paint float or special scaffolding to ensure that paint chips and grit are not discharged into the water.

3.2.2 Power tool clean to SSPC SP-3 or abrasive blast to SSPC SP-7 the vessel’s hull and superstructure to remove the markings identified above. Grind smooth all weld beads outlining where markings were installed. (Draft markings are not included).

3.2.3 Feather the surrounding surfaces to obtain a 3-inch wide smoothly tapered boundary from the existing paint to the prepared surface.

3.2.4 Prior to applying any paint, remove all dust, grease, oil, or other contaminants from all prepared areas in accordance with applicable local, state, and federal laws and regulations. Solvent wipe affected areas in accordance with SSPC SP-1.

3.2.5 Submit condition found report noting completion of surface preparation. The Coast Guard Inspector will verify all surface preparation.

3.2.6 Upon verification from the Coast Guard Inspector on all surface preparation, prime and coat all prepared surfaces to match existing adjacent surfaces in accordance with the applicable sections of SFLC Std Spec 6310.

3.3 Upon completion of preservation, remove all tarping and masking and restore affected areas. Submit CFR noting completion of work.

3.4 Restoration. Restore all interferences to their original condition in accordance with the General Requirements.
