08004 Non-Destructive Determination of Rust Creep

Modern high performance paint systems are so durable that when exposed to natural weathering they may show only slight signs of deterioration.   This means that new coatings being marketed have limited track records. Which creates an  increased reliance on accelerated laboratory testing to evaluate performance.

The demands on protective coatings used in offshore environments are very high and modern high performance paint systems are so durable that when exposed to natural weathering they may show only slight signs of deterioration. The best anticorrosive coating systems of today may continue to perform well for maybe 15-20 years. The use of new technologies also means that coatings being marketed have limited track record. This has resulted in a necessary increase in reliance on accelerated laboratory testing to evaluate coating performance. However, many of these accelerated exposure tests will not, within their exposure time, show negative effects on intact coating systems. Therefore rust creep from artificially made damage is receiving significant consideration.

Key Words: Non-destructive testing, NDT, rust creep, ISO 20340, NORSOK M-501

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.

This paper will critically review the current philosophies described in  ISO and NACE anti-corrosive performance test standards, taking into consideration correlation with natural exposure, track record, validity of "acceptance" or "pre-qualification criteria", dry film thickness and suggested areas for improvement.

New high-solids coatings are sometimes required to meet volatile organic compound (VOC) legislation. Lack of data on same needs accelerated test methods to evaluate performance. The test method must: • Be performed using commercially available equipment • Take a relatively short time period. • Correlate with real life exposure.
