Ensure cleanliness of prepared surface is as per specification (i.e.: SSPC SP-11, SP-10, SP WJ-2…).

Verify surface anchor profile using ASTM D4417-Methods B or C against SFLC Std Spec 6310. Conduct profile readings at a minimum of 5 locations for the first 1000-sqft area, and 2 locations for each succeeding 1000-sqft area.

Measure soluble salt conductivity in accordance with SSPC-Guide 15. Conduct 5 measurements per each 1000-sqft area (max. threshold: 70 microsiemens/cm for non-submerged surfaces, 30 microsiemens/cm for submerged surfaces).

CHECKPOINT 6 - PRIMER COAT APPLICATION

Verify environmental conditions (see CHECKPOINT 3).

Verify proper mixing and stand-in (induction) times.

Ensure no paint is applied when the temperature is expected to drop to freezing before the paint has dried.

Ensure surfaces are completely dry, unless otherwise allowed by the coating manufacturer(s).

Verify wet film thickness (WFT) at random, to prevent under or over application. Verify final DFT.

Brush out all runs, sags, drips, and puddles.

Perform visual inspection for holidays and other defects.

CHECKPOINT 7 – STRIPE COAT APPLICATION

Verify environmental conditions (see CHECKPOINT 3).

Ensure overcoating window is as per manufacturer’s instructions.

After primer coat (mist coat after inorganic zinc), brush-apply un-thinned coat of same primer paint over edges, weld seams, cut-outs, and areas of complex geometries @ 3-4 mils wet film thickness (WFT).

CHECKPOINT 8 – TOP COAT APPLICATION

Verify environmental conditions (see CHECKPOINT 3).

Ensure overcoating window is as per manufacturer’s instructions.

Verify proper mixing and stand-in (induction) times, as applicable.

Verify wet film thickness at random, to prevent under or over application.

Verify final system dry film thickness. Conduct 5 sets of 3 readings for each of the first 3 100-sqft areas, followed by 5 sets of 3 readings for each succeeding 1000-sqft area.

Ensure that system cure is in accordance with manufacturer's recommendation for intended service.

Ensure potable water tank exhaust ventilation is maintained continuously from and during coating application through final system cure, to exhaust all solvent to the atmosphere and to prevent solvent entrapment.

For immersion coatings (including tank U/W body), record date and time of the following events:

Final coat application: _____/_____; Return to service or removal from environment controls: _____/_____

CHECKPOINT 10 – RECORD KEEPING

Complete, sign, and submit all provided QA Inspection Forms.

QA-2 - QUALITY ASSURANCE INSPECTION FORM

· 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.

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.

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

3.2.2.2.1 The contractor may elect to apply the anti-abrasion icebrraking 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 shall be performed over first coat. Second coat application shall follow completion of side scan. Total DFT of both coats shall meet listed DFT of single coat anti-abrasion icebreaker DFT in SFLC Std Spec 6310, Appendix A. Application of coats shall be in accordance with manufacturer’s overcoating intervals.

3.2.2.3 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).

3.3 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 prolong 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.
