Structural, ballistic, and mobility requirements have led to the selection of aluminum alloy 2519 as the primary structural material for the Advanced Amphibious Assault Vehicle (AAAV). Two-year seawater alternate immersion exposures of welded AI 2519 panels with and without protective coatings were conducted to simulate the expected AAAV service environment.
This paper is a significant update to “Costing Considerations for Maintenance and New Construction Coating Work”1 on protective coating costing and selection co-authored by M. F. Melampy, M. P. Reina and K. R. Shields in 1998. Designed to assist the coatings engineer or specifier in identifying suitable protective coating systems for specific industrial environments.
Optimisation of maintenance and inspection programmes through risk analysis can be used for coating maintenance. The risk picture can be described by 1) Scenario, 2) Frequencies, and 3) Consequences, for protective coatings. A systematic approach for optimisation of the maintenance programme has been developed.
Requirements for corrosion protection for new large offshore wind farms are extended to 25 years’ maintenance-free service lifetime. Therefore, ISO 12944 is being updated. To bring down construction cost for offshore wind, initiatives have been taken to industrialize the coating application process and use standard components.
