    Inspection campaign


In December 2014, MMA conducted a 60km inspection campaign of the DomGas pipeline. The DomGas pipeline is approximately 90km long, of which 60km is subsea and ties into a subsea spool and riser at the LNG Jetty on Barrow Island, off the coast of Western Australia. Water depths along the subsea section range from zero to -16 meters.

MMA provided the following equipment and services to complete the work scope:

  • Surface GNSS positioning and heading systems • Underwater positioning system (USBL)
  • Remote helmsman navigation system
  • ROV inspection data logging and processing suite
  • Cathodic Potential measurement system (continuous & direct contact)
  • Personnel to provide project management & operations support

The work was successfully completed on-board the ROV and Air Dive Support Vessel, the Dryden, utilising the MMA owned Comanche Light Work Class ROV. A suite of inspection sensors and equipment including, cameras, fiber optic multiplexer unit and CP equipment were supplied by MMA and fitted to the ROV.
