Designer and builder of specialised vessels Vard has ordered four MAN 12V175D-MEM GenSets in connection with the building of a new purpose-built, cable-laying vessel (CLV) for NCT Offshore, a Danish subsea specialist.
The GenSets will form part of the vessel’s diesel-electric DP2 propulsion system, which includes a hybrid battery package.
Florian Keiler, Head of High Speed, MAN Energy Solutions, said: “This exciting project is just the latest in the rapidly-growing offshore-windfarm market. Happily for us, the 175D is strongly represented within this segment where it is commonly the engine of choice for owner and yard alike. In such a green environment-driven sector, the 175D’s inherent fuel efficiency and low emissions make it an ideal propulsion solution, either as a standalone or – as in this case – as part of a hybrid package. It is also the engine with the lowest total cost of ownership in the market with a small environmental footprint.”
The high-speed 175D GenSets will each come accompanied by compact MAN SCR (Selective Catalytic Reduction) systems. Furthermore, MAN Energy Solutions states that the engines have the lowest lube oil consumption on the market.
Featuring DP2 positioning and seakeeping systems, the CLV will be equipped with an intelligent power system solution for improved sustainability – encompassing batteries, switchboards, and shore connection – that will reduce fuel consumption and increase operability. The vessel will feature a bollard pull in excess of 60t, while maximum transit speed will exceed 14 knots.
MAN Energy Solutions offers the 175D engine range in three variants of 12-, 16- and 20-cylinders, with output ranging from 1,500kW to 4,400kW, optimised for propelling ferries, offshore support ships, tugs and other working vessels. The 175D was designed from the outset for low fuel consumption, coupled with compliance to the latest exhaust gas-emission standards and considering future-fuel requirements, where it is already approved for operation on biofuels, such as FAME and HVO.
