HIGH VOLTAGE POWER AND COMMUNICATION TRANSMISSION SYSTEM EPCI (JANSZ-IO COMPRESSION) - Supply and Installation of Concrete Mattress and Bulk Bags

Please refer to Sow for further information.

The Chevron Australia operated Gorgon Project is one of the world's largest natural gas projects and the largest single resource development in Australia's history. The Gorgon LNG and domestic gas plants on Barrow Island (BWI) are supplied by gas from the offshore Gorgon and Jansz-Io fields. The Jansz-Io Compression (J-IC) Project will use proven subsea compression technology to enhance the recoverability of the Jansz-Io field to maintain long-term natural gas supply to the gas processing facilities on BWI. Part of the original development plan for Gorgon, the J-IC Project involves the modification of the existing subsea gas gathering network in the Jansz-Io field.

Nexans Norway AS has been awarded a contract to engineer, manufacture and install a high voltage power cable from Barrow Island to an Normally Unattended Installation (NUI) semisubmersible Field Control Station (FCS). The scope comprises a 145kV HVAC cable of 135km, of which the nearest section to the FCS is dynamic in a lazy wave configuration, as well as supply of 15km of HV power and fibre optic cables to be installed on Barrow Island.

The HVAC power cable will cross eight pipelines/umbilicals along the route from BWI to the FCS. Prior to laying the cable all crossings will be prepared with concrete mattresses. After the power cable is laid on seabed it will be stabilised with rock installation and trenching within the shallow water section.
