Hyperbaric Test Facility

Power CSL have invested in a range of hyperbaric equipment designed specifically for the testing of subsea power cable and umbilical power core and joint components. The chambers are configured with sealing arrangement such that the ends of the cable under test can be accessed to allow electrical testing of the cable joint whilst at high pressure. Data loggers maintain a continuous record of pressure and temperature throughout the test cycle.

There are 4 test chambers available :

  • 48mm internal bore x 1.5 metre length : 300 bar max test pressure
  • 150mm internal bore x 4.0 metre length : 377 bar max test pressure
  • 300mm internal bore x 3.0 metre length : 50 bar max test pressure
  • 490mm internal bore x 7.0 metre length : 48 bar max text pressure

Power CSL would be pleased to provide a quotation for testing of third party products.
