The Australia business division of Chevron is current seeking approval from the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA).
Confirmation of approval will enable it to develop subsea and pipeline infrastructure at its cutting-edge Gorgon project.
Among the world’s largest liquified natural gas (LNG) projects, Gorgon is also the biggest single resource project in the history of Australia.
Gorgon includes pipeline infrastructure and offshore production wells that collect natural gas from the Gorgon and Jansz–Io fields and then directly transports it to a Barrow Island-based facility for processing.
To sustain gas supply to the Barrow Island facility and maintain present gas production rates there, Chevron Australia aims to fit a new subsea compression station along with appropriate infrastructure within the natural gas fields at Jansz–Io gas fields.
Proposed works currently include a typically unattended floating control station that is tethered to the seabed by multiple mooring lines, construction of the subsea compression station and spools, an umbilical that will supply power directly from the facility on Barrow Island to the control station, and flying leads (a type of power cable) that connect the subsea compression station to the field station. Additionally, another umbilical will be installed that transmits communications and power between the Jansz CDU and the field control station.
Further works are required, however, like rock stabilisation and establishing pipe crossings.
A leading petroleum refineries firm, Chevron is well-known for its first-class lubricants brand, Texaco, which produces a wide range of solutions from gear oil to grease.
