New MAN FGSS minimises methane slip
The FGSS will be installed on a new series of two dual-fuel, 6,500 pure car carriers for Wallenius Marine on charter to Volkswagen. Henrik Malm, Managing Director at MAN Energy Solutions, Sweden and Finland, claimed that the use of the high-pressure, boil-off-gas compressor to supply boil-off gas to the ME-GI high-pressure engine represented a world first.
An installed shaft generator will further reduce the running hours of the auxiliary engines.
The FGSSs for the vessels will be delivered during 2023. The scope of delivery includes the following:
- port- and starboard-side bunkering stations
- LNG storage tank with a volume of 2,300 m3
- tank connection space with low-pressure vaporizer, BOG heater and two LNG pumps
- high-pressure gas-handling equipment for delivery of gas to MAN B&W ME-GI two-stroke main engine
- boil-off gas (BOG) management system, including one high-pressure compressor
- on-board nitrogen-generation system
- control system as well as gas-detection system.
MAN Cryo offers systems for the storage, distribution and handling of liquefied gases and supplied the world’s first LNG fuel-gas system for the Glutra ferry in Norway in 1999, a vessel that is still operational. More recently, in 2013, MAN Cryo supplied the world’s first bunker vessel, the SeaGas.
