MAN to supply dual-fuel propulsion system on new NSCV

MAN Diesel & Turbo has released a statement claiming that it has signed a contract with Sembcorp Marine to supply the dual-fuel propulsion system for a new semi-submersible crane vessel (NSCV), which is being built for Heerema Offshore Services. The system will include exhaust-gas after-treatment.

The package will ensure fuel-flexibility and make sure that the vessel meets NOx Tier III emission limits, both when operating on LNG and on MGO with the help of the SCR system.

MAN will provide 12 MAN 8L51/60DF four-stroke engines and 12 MAN selective catalytic reduction (SCR) systems. The overall output of these engines is estimated by MAN to be approximately 96 MW.

The engines are scheduled for delivery in early 2017, and the vessel is due to be delivered in 2018. Once complete, the vessel will be the first of its size to have dual-fuel technology.

Lex Nijsen, the Head of Four-Stroke Marine – MAN Diesel & 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. The solution MAN Diesel & Turbo is delivering to Sembcorp Marine and Heerema is reliable, efficient, flexible and meets the highest safety and environmental standards.”
