Since 1982, there has been a move to Thermal Sprayed Aluminum (TSA) coating in the “splash zone” of offshore structures. Our experience indicates that an experience applicator, good surface preparation and quality of wire combined to achieve required thickness and apply the sealer to seal the entire surface.
Hot dip galvanizing steel articles after fabrication is one of the most widely used methods to provide corrosion protection. As a final step in the process, the hot dip galvanized coating is inspected for compliance with specifications. Correct measurement techniques and accurate interpretation of the results are necessary to provide an acceptable hot dip galvanized coating.
This paper will consider the performance and relevance to static situations of the key types of Cathodic dip painting (CDP) Antifoulings (Rosin Modified types), the current tin free polishing types (typically acrylates of various types), and low energy surface types. Both field experience and laboratory work will be considered.
