COPENHAGEN, Denmark – China Merchant Heavy Industry (CMHI) has ordered 6 × MAN 12V32/44CR main engines from MAN Energy Solutions for Jan De Nul Group’s floating installation crane vessel Les Alizés.
Delivering a cumulative output of 43,200 kW, the common-rail engines will each feature an enhanced, MAN-supplied SCR (selective catalytic reduction) system for IMO Tier III-compliance. It will also meet the Euro Stage V-compliant NOx-emission limit. The enhanced NOx-reduction rate is essential for the newbuild to fulfill the exacting ULEv (Ultra Low Emission vessel) standard for better air quality, characterized by very low NOx and particle emissions.
The 32/44CR engines are expected to be delivered with the company’s ECOMAP feature. The CR-system’s flexibility permits the engine to be programed to run along different fuel-consumption-versus-power characteristics, with each having its efficiency optimum at a different load point.
The company said its high engine-output is available even at high ambient temperatures, as well as at the high exhaust-gas back-pressures resulting from the extensive exhaust-gas treatment equipment, which is mandatory for the ULEv notation.
The Les Alizés will be built at CMHI’s shipyard in Jiangsu province, eastern China, and is scheduled for delivery in 2022. It is expected to have a lifting capacity of 5,000 metric tons.
