Fugro tapped to survey mammoth Gorgon Project

December 23, 2013

Fugro will provide survey services in support of Subsea 7 Australia Contracting Pty Ltd’s heavy lift and tie-ins contract on Chevron’s Gorgon Project, located about 60km offshore Western Australia.

The contract involves the provision of a DP2 survey vessel and deepwater work-class remotely operated vehicles (ROVs). Through offshore supply ship Rem Etive, Fugro will install and calibrate long baseline arrays, along with spoolpiece metrology operations on a 24-hour basis. Fugro will also provide personnel and equipment.

The Grogan Project consists of the developing Grogan and Jansz-Io gas fields, located in the Greater Gorgon area, 130 - 220km off the northwest coast of Australia. According to Chevron, it stands as one of the world’s largest natural gas projects and the largest single resource development in Australia’s history.

The project will see the construction of a 15.6MTPA liquefied natural gas (LNG) plant on Barrow Island, the Class A Nature Reserve where the Grogan project calls home. A gas plant supplying domestic gas is also planned. LNG will also be exported internationally through a 2.1km loading jetty.

Water depths in the area range from 200-1350m.

Approximately 75% complete after four years of construction, costs of the foundation project is US$54 billion (AU$55 billion), with plant startup and first gas planned for mid-2015, according to Chevron’s December capex announcement.

The contract commences in December 2013 and is expected to run for approximately 70 days, excluding options. No information on the amount of the contract was released.

Chevron’s Australia subsidiary is the operator of the Gorgon Project with a 47.3% working interest (WI), partnering with the Australian subsidiaries of ExxonMobil (25%), Shell (25%), Osaka Gas (1.25%), Tokyo Gas (1%), and Chubu Electric Power (0.417%) in a joint venture.
