Wärtsilä Moss to supply inert gas generators for Ichthys FPSO

Offshore staff

POOLE, UK – Wärtsilä Moss AS has won a contract with Daewoo Shipbuilding & Marine Engineering Co. (DSME) to supply inert gas generator (IGG) units to an FPSO for the Inpex-operated Ichthys LNG project in the Browse basin offshore Western Australia.

Wärtsilä Moss’ scope of supply is two identical IGG skids designed for installation in a hazardous area to prevent risk of explosion, and forming part of the topside module with pressure vacuum breakers and control systems as loose supply for installation by DSME.

“The IGG units perform the same function as they would do on a tanker vessel but as these units fire fuel gas they are positioned on topside to avoid the use of fuel gas in an enclosed space,” said Odd Ivar Lindlov, GM, Inert Gas Systems Offshore, Wärtsilä Moss. “This is a requirement from TOTAL to ensure natural ventilation of the topside.”
