Chevron has developed the Gorgon and Jansz gas fields located within the Greater Gorgon area, off the northwest coast of Western Australia. The Gorgon Stage 2 Project supplements the existing Gorgon and Jansz gas field development with additional offshore wells and supporting subsea infrastructure.

Allseas, which has been awarded an offshore pipeline installation scope, is now seeking expressions of interest from contractors capable of providing an anchor handling vessel and associated services for operations during the pipeline installation work.

The contract award is planned from the second quarter of 2020, with the execution of works expected in Q4 2020/Q1 2021 period.

Contractors, which have until June 21, 2019, to express interest, need to be able to provide an Anchor Handling Tug suitable for deployment of anchors and associated initiation wires of approximately 2500 meters.

The vessel needs to be capable of setting anchors and provide anchor test up to 150 t using a combination of the vessel working wire and initiation wire. Furthermore, the contractors need to have a back-up vessel in case the primary vessel is unavailable for the works.

Allseas’ pipelay vessel Audacia and offshore construction vessel Oceanic will be working on the Gorgon Stage 2 (GS2) pipeline installation in late 2020 and early 2021.

Gorgon is one of the world’s largest LNG projects and the largest single resource project in Australia’s history.

Located on Barrow Island, Gorgon comprises a three-train, 15.6 million tonnes per year LNG facility and a domestic gas plant with the capacity to supply 300 terajoules of gas per day to Western Australia.

Chevron sanctioned the second phase of the project in April 2018, and it said the development fit “within Chevron’s previously announced annual investment range of $18-20 billion through 2020.”

The Gorgon Project is operated by Chevron Australia and is a joint venture of the Australian subsidiaries of Chevron (47.3 percent), ExxonMobil (25 percent), Shell (25 percent), Osaka Gas (1.25 percent), Tokyo Gas (1 percent) and JERA (0.417 percent).
