CHECKPOINT 1 – COATING SYSTEM COMPLIANCE

Ensure all coatings are in compliance with SFLC Std Spec 6310, Appendix C.

CHECKPOINT 2 - PAINT STORAGE

Ensure all coatings are kept at a temperature of 65 to 85°F at all times, unless otherwise specified by the coating mfgr.

CHECKPOINT 3 - AMBIENT CONDITIONS

Ensure surface and surrounding temperatures are each between 50 and 90°F for water-containing coatings, and 35 and 95°F for other coatings, unless otherwise specified by the coating manufacturer(s).

Ensure maximum relative humidity (RH) is as follows, from surface preparations through final curing of topcoat: 50% for tanks, voids, and vent plenum; and 85% for all other areas, unless otherwise specified by manufacturer(s).

Ensure surface temperature is at least 5°F above the dew point, unless otherwise specified by the coating mfgr.

CHECKPOINT 4 - PRE-SURFACE PREPARATION

Remove surface contaminants (soluble salts, loose rust, mud, and marine growth) with low pressure fresh water wash down (maximum 5,000 psi). If oil and grease are present, perform solvent cleaning, as per SSPC SP-1.

Verify equipment setup, blast media, and surface preparation methods match designated test coupon.

CHECKPOINT 5 - SURFACE PREPARATION

Verify environmental conditions (see CHECKPOINT 3).

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

· Provide all qualified personnel required to complete the requirements contained herein at an on-site location.

3.1.3 Protective measures. The Contractor shall furnish and install suitable covering to seal off and protect all non-affected surfaces/equipment and spaces in the vicinity of the work area against contamination during the performance of work. Upon completion of work, remove protective material and inspect for the presence of contamination. Clean all equipment and spaces, contaminated due to improper protection, to original condition of cleanliness.

3.2.1 Hand held scanner. Areas that are accessible but cannot be scanned by scanning equipment shall be hand-scanned. Any repair areas found during the hand scan shall be marked on the ship’s hull and their approximate positions recorded on the plate drawings and report summary. All hand held scanning procedures shall follow the following parameters:

· The Contractor shall calibrate the hand held meter each time it is powered up for use using an ASNT certified calibration block made of mild steel.

· The Contractor shall scan all areas within six inches of automated scanning obstacles to include; sea suctions, discharges, rudderposts, anodes, stern tubes, drydock blocks and areas blocked by immovable scaffolding, using a hand held meter set to a resolution of 2.0”x 2.0”.

· The Cotnractor shall provide supplemental hand held readings in accordance with ASNT Recommended Practice No. SNT-TC-1A 2006 on any area of the hull identifed as thinner than the criteria for repair defined in paragraph 3.2.5.

· The Contractor shall scan any areas where the automated scanner lost data due to sharp dents, surface irregularities, roughness, etc. using a hand held meter with a resolution set to 1.0” x 1.0”.

3.2.2 All Under-Water Body and Freeboard plating shall adhere to the following evaluation criteria:

· 4-5 LB plate – C scan data indicating wastage greater than or equal to 15% of nominal plate thickness shall be highlighted in RED and designated a repair area.
