Composite wrapped repairs are frequently used on offshore oil and gas pipework, but are intended to be temporary. Our client had a large number of such repairs, many on pipework that was now operating at reduced pressure. They wanted to know whether the lives of these repairs could be safely extended.
We were able to demonstrate to both the client’s and the regulator’s satisfaction that the repairs were sounds for very many years’ time. As a further check we analysed a repair that was known to have failed, and correctly predicted the mechanism. Our client was able to divert resources to replacing those repairs with shorter lives.
