This paper discusses the problems and mitigation of CUI in the Petrochemical industry as it was thirty years ago. With increased requirement for insulation since then the problem has only become more serious.

Costs of CUI

In Australia, the yearly cost of asset maintenance is estimated to be approximately $32 billion. Avoidable corrosion damage, such as CUI, accounts for $8 billion of this and continues to have a major economic impact on industry and the wider community. Each year around the world there are hundreds of failures and incidents – to varying degrees of severity – caused by CUI.

In Europe Corrosion Under Insulation in ageing pipelines accounts for 20% of the major oil and gas incidents reported within the EU since 1984 . Many assets in the North Sea are operating beyond their expected design life and 60% of pipe failures are caused by CUI. The Corrosion Challenge has been setup by the The Oil & Gas Technology Centre looking for innovative ideas and concepts to predict, detect, inspect, and mitigate CUI.
It will enhance safety, improve production efficiency and help us unlock the full potential of the UKCS.

There is over a one million pounds available for investment in new ideas

Attend a CUI Technical Event

If you are involved with pipelines this is for you.
Corrosion Under Insulation Technical EventTo help you stay up to date with all things CUI we are running hands on  CUI technical workshops in Perth, Sydney  and New Plymouth.  Peter Brock an International Speaker is leading these workshops.

Train to be a  NACE Pipeline Engineer

There is a 5 day course running in July in  Brisbane
