Operator, North America
Plant equipment and piping
Maintenance costs spread effectively over five years
Corrosion under insulation (CUI) has presented a major threat to asset integrity for many years. Implementing an effective management programme here, particularly for piping, can be a major undertaking. We were asked by a US plant operator to assign all its insulated equipment and piping to a managed CUI programme and prioritise the inspection and maintenance plan.
How we helped
Our experts collected the appropriate data and predicted the risk of CUI damage, based on design and inspection information. We carried out both visual and non-destructive examination (NDE) inspections, updating the risk profile based on the findings.
Alongside establishing a manageable CUI programme, we developed a 10-year inspection plan with the client. The current and future risk informed our prioritised list of items requiring future inspections.
As a result of the project, our client could spread its multi-million dollar maintenance costs over a five-year period, with maintained or reduced risk levels. All of our objectives were met within six months.
