Local opportunities in NWS gas fields
TehcnipFMC is working with ICNWA to identify local capability for Woodside Petroleum’s North West Shelf (NWS) Subsea Tieback Program.
The program focuses on using existing infrastructure to develop reserves from current and undeveloped NWS Project fields.
The oil and gas fields are about 125 kilometres north-west of Karratha, Western Australia in water ranging between 80 and 131 metres’ deep and covering a total area of 3,134 square kilometres.
The Perseus field represents about one third of current gas resources. Other producing fields include North Rankin, Goodwyn, Angel, Searipple, Cossack, Wanaea, Lambert and Hermes.
Undeveloped gas reserves include Wilcox, Sculptor, Rankin, Dockrell, Lambert Deep, Pemberton, Lady Nora, Keast, Dixon and Gaea.
The NWS Project fields are the largest single supplier of pipeline gas in Western Australia and have exported more than 5,300 cargoes internationally since it began LNG production in 1989.
The Tieback program will use the same types of equipment, methodology and approach to contracting to develop reserves from these fields that will connect into the NWS Project’s existing offshore infrastructure.
The NWS Project’s onshore Karratha Gas Plant (KGP) consists of five LNG trains and a domestic gas plant, located on the Burrup Peninsula of North Western Australia. The plant processes raw dehydrated gas. It exports LNG, condensate and LPG, as well as distributes conditioned gas via the domestic gas pipeline.
Offshore, the North Rankin Complex, the Goodwyn A platform (GWA) and the Angel platform dehydrate the raw hydrocarbons for export via a dual subsea pipeline system to the gas plant.
Under the Australian Industry Participation plan, Woodside is committed to ensuring Australian companies are given the opportunity to supply into the project.
A number of work packages are currently open on ICN Gateway.
