Wärtsilä Moss has secured a contract from Daewoo Shipbuilding & Marine Engineering Co (DSME) to supply inert gas generator (IGG) units to two identical IGG skids for installation in a hazardous area.
The IGG units are for a floating production, storage and offloading (FPSO) vessel for the INPEX-operated Ichthys LNG project in the Browse Basin off Western Australia.
The FPSO is being built by DSME at its shipyard in South Korea and is scheduled for delivery in April 2016. It is expected to comply with strict Australian environmental standards and has a projected lifespan of 40 years.
The identical IGG skids will help prevent the risk of explosion, forming part of the topside module with pressure vacuum (PV) breakers and control systems. Odd Ivar Lindlov of Wärtsilä Moss said the company has a good working relationship with Total oil and gas group, a joint venture partner with INPEX.
"Recent projects have included the Pazflor and Clov field developments in which we have received very good feedback from the operating units," said Lindlov.
The IGG units are installed to serve the primary operation of the FPSO, which will transfer condensate to tankers for delivery to markets. Topside modules will allow the drilling, production and/or processing of offshore hydrocarbons. Gas from the field will undergo preliminary processing offshore before being exported through an 889km subsea pipeline to onshore processing facilities in Darwin.
The Ichthys LNG Project is expected to produce 8.4 million tons of liquefied natural gas (LNG) and 1.6 million tons of liquefied petroleum gas (LPG) per annum, along with 100,000 barrels of condensate each day.
