Heidrun FSU

Wärtsilä will supply inert gas systems, deepwell pumps and fire water packages to a permanent FSU to serve the Heidrun Oil & Gas Field.

Wärtsilä Moss inert gas systems will also be supplied to two shuttle tankers that will support the FSU. Crude oil output of the field will be loaded to the FSU vessel through subsea pipeline and underwater hoses. The oil will be lifted from the FSU vessel to shuttle tankers through offloading hose-strings.

Wärtsilä Moss inert gas systems prevent the gas mixture in the FSU’s cargo tanks or bunkers from reaching a range where explosions could occur. Inert gas maintains the oxygen content of the tank atmosphere below 8%, thus making the air and hydrocarbon gas mixture in the tank too lean to ignite.

The Wärtsilä Hamworthy pumping equipment meets and exceeds local and international standards. Furthermore, the electrically driven systems feature low noise levels, high system efficiency, and simple maintenance.
