The technology group Wärtsilä’s integrated propulsion and cargo handling solution will deliver high efficiency for a new 30,000 cbm LNG vessel. The ship is being built at the Hyundai Mipo Dockyard (HMD) in South Korea on behalf of Norway based Knutsen OAS Shipping. The Wärtsilä solutions will ensure effective interfacing between the vessel’s propulsion, onboard auxiliary power generation, and cargo control processes. Such integration is essential in achieving full fuel-efficiency.
The advanced Wärtsilä cargo handling system includes the fuel supply, cargo control system, boil-off gas (BOG) reliquefaction, and safety management. The 5-cylinder WinGD X52DF dual-fuel main engine and the Wärtsilä auxiliary dual-fuel engines are essential consumers for the BOG management system, which monitors and controls the cryogenic cargo, to ensure, in combination with a Wärtsilä developed mixed refrigerant re-liquefaction unit, all time control over the cargo tank pressure and temperature. The vessel will be one of the first LNG carriers in its size to be equipped with space-saving C-type bi-lobe cargo tanks.
The latest development of the LNG infrastructure provides clear evidence of the increasing importance of LNG fuel to the marine industry. Wärtsilä has a lot of experience and know-how throughout the LNG value chain, and we are confident that their solutions are what we need for this latest expansion to our fleet.
