3.1.3.1 Abide by all applicable environmental protection tasks, as specified in paragraph in SFLC Std Spec 0000, Appendix B (Requirements for Environmental Protection).

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

· Cranes and controls

· Winches

· Ready service lockers

· Wash down counter measure fittings

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 below listed :

· Small boats

· Wash down counter measure fittings

· Drains and covers

· Hatches and scuttles

· Machinery and equipment (e.g. weapons, radars/antennas, FAS system, stern boat launch, cranes, winches, and brakes)

· Ventilation trunks

· Ready service lockers

· Outfits and foundations (e.g. chocks, cleats, cat paws)

· Controls and terminals

· Speakers, and supports

· Lights and supports

· Sensors and supports

· Piping and supports

· Cables and supports

3.1.5 Work locations. The concerned work areas are listed in Tables 1 and 2. See the applicable drawings in section 2 for guidance, locations, and details.

3.1.6 Materials. Any new components, parts, and paints shall be of the same color, comparable and matching material properties as the existing components/parts. Use references in section 1, 2 and SFLC Std Spec 6310 for guidance, required materials, and details.

3.1.7 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.

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

3.1.7.2 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.

3.1.8 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 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 AND CAUTION!

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

2. Initial removal of the coating system around deck edges, fittings, and deck coaming may be by power tool cleaning in accordance with SSPC-SP-11.

3. Flight deck surfaces are constructed of HY-AH-36 and HSLA-80 steel and may NOT be heated to remove the existing covering.

4. During pier side surface preparation, suitable means to contain generated dust, waste water, paint chips, spent abrasives, and overspray must be provided or employed, as applicable. Plywood or net/canvas barriers are typically used to surround the area being blasted to contain stray steel shot. When net barriers are used, the mesh size of the netting material must be small enough to ensure that the steel shot will be contained. In addition, net barriers, when used, must be overlapped where attached to stanchions, and anchored at the bottom for the entire net’s length between stanchions, to limit the clean–up and localize the blast medium. Steel shot on a deck is a foreign object damage (FOD) hazard and extreme care must be taken to prevent slipping when walking over contaminated areas.

3.1.9 Work coordination. The Contractor shall coordinate the accomplishment of this work item with the following work items :

· Deck Components and Outfits, Preserve

· Superstructure, Preserve

· Tenting, Provide

3.2 Quality assurances and controls. 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”), and the quality controls specified in SFLC Std Spec 6310, paragraph 3.1.10 (Coating inspection) and 3.1.15 (Coating system tests).

3.3 Inspection. The Contractor shall inspect of all exposed deck areas in Table 1 after removing/cleaning deck covering and prior to priming deck surfaces in accordance with SFLC Std Spec 0740. Submit a CFR.

3.3.1 Visual inspection (VT). The Contractor shall visually inspect of all exposed deck areas in Tables 1 and 2 for any pitting, corrosion, and erosion.

3.3.2 Ultrasonic test (UT). The Contractor shall take a total of 200 UT measurements on the exposed substrates as designated by the Coast Guard Inspector, in accordance with SFLC Std Spec 0740, Appendix C.

3.3.3 Pit. The Contractor shall measure approximately 400 pits on the exposed substrates as designated by the Coast Guard Inspector using a Contractor supplied ‘Pit Gauge’, if pitting is found during visual inspection. The results of these measurements should also be included in the inspection report showing where pit measurements were taken and the depth of the pit.

3.4 Substrate repair and fairing.
