4 (Rev-0)
QA-1 - QUALITY ASSURANCE INSPECTION FORM
(PRESERVATION CHECKLIST)
Vessel Name Hull # Work Item # Work Item Title
Location of Work (incl. frame #’s) Area (sqft)
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.
