The work aims to facilitate design of platform coating scheme as well as development and certification of coating products by analyzing standards and relevant technical documents of protective coatings for offshore platform, and expounding approval test of coating systems. Requirements of standards, coating systems, coating products and property were analyzed and interpreted one by one by making a painstaking investigation. Coating systems and coating structures in different corrosion environments were obtained. Anti-corrosive coatings, which were commonly applied to the platform, were classified based upon base, interlayer and surface coating structures. Performance requirements and test methods of the coating systems in different corrosion environment were provided. The coating systems for offshore platform could be designed according to NORSOK M501 and NACE SP 0108 which complemented each other. The coating systems for offshore platform should be approved according to NORSOK M501 which employed test method of ISO20340, including cyclic aging test, seawater immersion test and cathodic abruption test. In order to build coating systems for offshore platform, such varieties as zinc rich paint, epoxy antirust paint, epoxy micaceous iron, glass flake epoxy paint, surface tolerant coating, thick-build epoxy paint, solvent-free epoxy paint, novalac epoxy paint, polyurethane paint and polysiloxane paint should be developed.
