Corrosion under Insulation (CUI) has been a significant problem for the offshore industry for more than 40 years and is a major cause of equipment outages, unexpected and catastrophic failures, production losses and potentially both environmental damage and injury or loss of life.

During the summer of 2007, a graduate engineering student, Miguel Lamsaki, undertook a review of CUI as a follow-up to the Asset Integrity Workshop held earlier in the year. The project examined corrosion processes; the susceptibility of various materials used in offshore facilities to different types of corrosion; coating and insulation materials and systems; sealants, cladding and jacketing; visual, non-destructive and risk based inspection approaches; and the impact of environmental conditions that are present on the east coast of Canada on CUI.

The objectives for PRAC were to identify opportunities for R&D activities that would address some of the longstanding issues related to CUI, and perhaps suggest other follow-up activities that would complement the Asset Integrity Workshop.
