Opportunities listed below are for Chevron Australia Pty Ltd packages specifically for Janz-Io Compression. Australia-wide contracts utilised for Jansz-Io Compression will be listed on the Chevron Australia Operations page.
Project Description
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 Jansz-Io Compression (J-IC) Project objective is to unlock low pressure reserves from the Jansz-Io reservoir and maintain plateau production rates to the Gorgon Project facilities on Barrow Island (BWI). The J-IC Project is therefore an upgrade to an existing facility.
The development will comprise of two subsea compression stations connected via a manifold structure to the Jansz-Io Midline Pipeline Termination Structure and the installation of the following supporting infrastructure:
New power generation capacity (as required) and cross-island High Voltage (HV) power cables on BWI;
Offshore (subsea) HV cables; and
Field Control Station (FCS), an offshore normally unattended installation semi-submersible electrical andcontrols distribution platform.

The Project is Operated by Chevron Australia Pty Ltd (Operator) on behalf of the Gorgon Joint Venturers and the Jansz-Io Unit Joint Ventures.
1) the Gorgon Joint Venturers being: Chevron Australia Pty Ltd; Chevron (TAPL) Pty Ltd; Shell Australia Pty Ltd; Mobil Australia Resources Company Pty Ltd; Osaka Gas Gorgon Pty Ltd; Tokyo Gas Gorgon Pty Ltd; and JERA Gorgon Pty Ltd; and
2) the Jansz-Io Unit Joint Ventures being the same parties as the above.
Project Location
The Jansz-Io gas fields are situated approximately 190 kilometres offshore and Barrow Island (BWI) approximately 70 kilometres off the north-west coast of Western Australia.

WA AUSTRALIAThe 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.

WA AUSTRALIANexans 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.
