UK Health & Safety Executive seeks contributions towards corrosion under insulation research

23 August 2022

The UK Health & Safety Executive (HSE) is hosting a workshop to discuss the options for a Shared Research Project on the topic of Corrosion under insulation (CUI). The HSE is welcoming individuals to join the workshop to discuss the challenges and identify opportunities posed by CUI.

Corrosion under insulation (CUI) is prevalent on major hazard plant, both on and offshore, including nuclear and chemical plants, oil refineries and offshore installations. Developments in coatings, insulation materials, cladding systems and installation practices have led to some improvements, however the unpredictable nature of CUI, combined with the associated difficulties of inspecting it, and subsequently detecting anomalies, makes ongoing integrity management extremely challenging.

Consequently, CUI continues to represent a major safety threat, having been responsible for a number of major hydrocarbon releases and presenting industry with a range of business assurance and continuity challenges that carry with them significant costs each year.

Despite promising developments in managing CUI over recent decades, it remains a challenging issue that requires a fresh approach. Therefore, on September 15, the HSE will be hosting a workshop to consider the threat of CUI from a lifecycle perspective and to discuss the options for a Shared Research Project on this important topic.

The workshop, to be held at HSE's Science and Research Centre in Buxton, will provide a forum for discussing challenges and identifying opportunities for shared research to address them. The basis on which this research can be undertaken will be a key outcome of the meeting.

To register your interest in attending the workshop, contact David Johnson (
