The situation
A US Gulf of Mexico operator had integrity concerns regarding the topsides unbonded flexible pipe jumpers which connect steel catenary risers to the process system of a Tension Leg Platform.
There was insufficient data available on these legacy pipes to be able to make an informed decision regarding safe remnant life.
Our solution
We carried out the forensic dissection of one of the jumpers carrying out intensive testing of the metallic and polymeric layers and then used this information to inform the life extension studies for the adjacent topsides jumpers.
The outcome was continued safe operation with a clearer understanding of the utilisation of each of the pipe’s layers.
