AMPP Marine Coatings case studies
AMPP Marine Coatings · Put your knowledge to work in context.
The Marine Coatings Inspector credential is offered within the AMPP certification portfolio. AMPP describes itself as "the largest global community for corrosion and coatings expertise" and states that its programs "cover cathodic protection, coating inspection, protective coatings, corrosion prevention and more." This independent study page organizes preparation around four equally weighted domains: marine coatings inspection fundamentals; surface preparation for marine coatings; coating application and materials; and inspection, testing, and quality control. The AMPP Marine Coatings case studies are 5 cases and about 2,815 words.
1Salt Contamination Showdown on a Ballast Tank Recoat
A yard is recoating the internal ballast tank of a 12-year-old bulk carrier. After abrasive blasting to Sa 2.5, the surface is a uniform grey-white.
