Manifold Testing

Testing high-pressure equipment must always be done properly and with the right equipment to ensure the safety of the people conducting and witnessing the testing. An equipment failure and the sudden release of high-pressure gas or liquid can be catastrophic to both personnel and facilities. A major oil company and its oilfield equipment supply partner approached OPT to develop and supply safety cages to contain equipment that was being pressure tested on a subsea manifold piping structure.

Manifold Testing
















The purpose of the device, called an independent locking mechanism (ILM), is to safely and effectively prevent any sudden release of test plugs used to cap off and pressure test subsea manifold equipment. Should a test plug mechanically fail, the ILM will keep it safely in place so that it cannot harm anyone or cause damage to the manifold itself.


OPT used finite element analysis to study and confirm the ILM's ability to withstand the impact loading that could occur in a test plug failure. The test plugs are quite large and the ILM has to withstand potential loads in excess 1.5 million pounds. The novel design of the two-ton ILM allows a single design to be used for the numerous different test plugs employed during manifold testing.
