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 and controls distribution platform.
