MAN propulsion for offshore installation vessel

The contract is for Heerema Offshore Services’ new semi-submerse crane vessel (NSCV).

Lex Nijsen, head of four-stroke marine at MAN Diesel and Turbo, said: “The entire project has special requirements in all aspects – it is absolutely a customised solution and a notable feather in our cap to have been selected as propulsion-system supplier for this unique vessel.”

“This is not just the largest, dual-fuel propulsion system ever featured on a single vessel, it also ensures Tier-III compliance in all operational scenarios, whether in gas- or MGO-modes, and whether within or without NOx Tier III-controlled areas,” he added.

Signed on 30 October 2015, the contract provides 12 MAN 8L51/60DF four-stroke engines and 12 MAN selective catalytic reduction systems.

MAN claims that with the total power output of the engines being 96 MW it will be one of the largest engine installations the world has ever seen aboard a single ship.

Engine is scheduled for delivery in the first quarter of 2017 and the vessel delivery is due in the fourth quarter of 2018.

The package ensures full fuel-flexibility and meets NOx Tier III emission limits at all times. MAN states that the engines maintain their high efficiency, also during SCR operation, through integrated and customised control strategies.

With a length of 220m and a width of 102m, the NSCV is said to be one of the world’s largest crane vessels.
