[4S/yim502] ABS Guidance Notes on The Inspection, Maintenance and The Application of Marine Coatings Systems

These Guidance Notes start with an explanation of the chemistry and mechanics of corrosion. While coatings act as a barrier to corrosion, they are porous. The Guidance Notes review the way coatings work to reduce corrosion rates. The myriad of different coatings available can be confusing without a framework to aid understanding. These Notes define the generic categories and their characteristics.
The methods of surface preparation are introduced along with safety guidance and the advantages or disadvantages of each. The factors affecting coating application are examined. These include environmental controls, film thicknesses and the methods of application, among others. Coating technology uses specific measuring equipment and the typical devices are briefly described. In addition to coating technology, the proliferation of coating regulations are explained in context for ballast water tanks, void spaces, outer shell and cargo holds.
Once a vessel is in-service the coatings are subject to various stresses. To aid in the assessment of how the coatings are performing, typical failures are illustrated and guidance is provided on their repair and maintenance.
Also summarized is the ABS Guide for the Class Notation Coating Performance Standard (CPS) which details the procedure to obtain the ABS CPS notation and provides useful summary information on the responsibilities of the various parties during the coating application process.
Still under discussion at IMO is the extension of the coatings regulatory regime to cover cargo holds/tanks as well as void spaces. In particular, void spaces below bulkhead decks, within and forward of the cargo area of oil tankers and the cargo length of bulk carriers.
