MAN Diesel & Turbo has signed a contract on 30 October, 2015 with Sembcorp Marine in Singapore to supply the dual-fuel propulsion system – including exhaust-gas after-treatment – for a New Semi-submersible Crane Vessel (NSCV) for Heerema Offshore Services.
The scope of the contract provides for a dozen each of MAN 8L51/60DF four-stroke engines and MAN SCR (Selective Catalytic Reduction) systems. MAN Diesel & Turbo states that the total power output of the engines is some 96 MW and one of the largest engine installations the world has ever seen aboard a single ship.
It is the first vessel of this size to feature dual- fuel technology and, upon completion, will be the largest vessel of its kind globally. Engine delivery is scheduled for Q1, 2017 with vessel delivery due in Q4, 2018.
MAN Diesel & Turbo states that the engines maintain their high efficiency – also during SCR operation – through integrated and customized control strategies.
The entire project is absolutely a customized solution. 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 II-controlled areas.
The solution MAN Diesel & Turbo which is to be delivered to Sembcorp Marine and Heerema is reliable, efficient, and flexible and meets the highest safety and environmental standards.
