China Merchant Heavy Industry (CMHI) has placed an order for six MAN main engines for the building of a new 5,000 tonne floating installation crane vessel for the Jan De Nul Group.
The Les Alizés will be built at CMHI’s shipyard in Jiangsu province, eastern China, and is scheduled for delivery in 2022. The vessel will be powered by the MAN 12V32/44CR, delivering a cumulative output of 43,200 kW. The common-rail engines also feature a MAN-supplied SCR system for IMO Tier III-compliance and will also meet the Euro Stage V-compliant NOx-emission limit.
“The MAN 32/44CR’s robust design is proven across many applications and I’m very happy to see it chosen again for such an exciting project,” commented Lex Nijsen, head of four-stroke marine sales – MAN Energy Solutions. “MAN Energy Solutions has previously worked with Jan De Nul Group on many of its vessels and recently provided four 12V32/44CR engines to CMHI for a major semi-submersible project,” he added.
The engines will be delivered with the company’s ECOMAP feature. The CR-system’s flexibility allows the engine to be programmed to run along different fuel-consumption-versus-power characteristics, with each having its efficiency optimum at a different load point.
Another key 32/44CR characteristic is that 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.
