Pressure testing subsea electrical and fiber optic connector systems

(Ref: SO575, Equip No. 2149)

Configured horizontally, this pressure vessel is used for carrying out qualification testing & production FATs on electrical and fiber-optic connector systems for subsea power and communications.

It has the ability to simulate most subsea extreme operating conditions by heating, chilling and agitation of the testing media (seawater with sand & silt), whilst allowing the test components to be manipulated; replicating the mate/de-mate functionality of the equipment whilst live electrical testing is performed.

For such a large pressure vessel, the bolted closure design was chosen to optimize and ensure longevity of the vessel closure sealing element whilst maximising the available space within the vessel. A bespoke bolt tensioning device was designed and manufactured to ensure the tightening sequence and operating torque of the Bolting was equally obtained and a Hydraulic closure control system.
