Experimental design to study corrosion under insulation in harsh marine environments
Corrosion under insulation (CUI) is a serious issue in harsh marine environments. Corrosion damage can have catastrophic effects on health and safety, asset integrity, the environment, and productivity if it is not detected and managed early. Limited information is available for CUI in marine environments. To overcome this issue, three types of corrosion tests are proposed: Determination of the effect of environmental factors on CUI using laboratory simulation, field testing, and accelerated marine atmosphere testing for CUI. This paper describes the methodology for developing statistically significant data to evaluate CUI in harsh marine field conditions, develop an accelerated laboratory test procedure to simulate CUI, develop a model of CUI rate, and develop risk-based remaining life assessment model for assets under CUI attack.
