China Merchant Heavy Industry (CMHI) has ordered six MAN 12V32/44CR main engines in connection with the building of a new 5,000-tonne floating installation crane vessel Les Alizés for Jan De Nul Group, an international maritime construction expert.

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, and will also meet the even-stricter Euro Stage V-compliant NOx-emission limit.

The enhanced NOx-reduction rate is essential for the newbuilding to fulfill the exacting ULEV (Ultra Low Emission vessel) standard for better air quality, characterised by very low NOx and particle emissions.

Les Alizés will be built at CMHI’s shipyard in Jiangsu province, eastern China, and is scheduled for delivery in 2022.

Jan De Nul Group is a world leader in dredging and offshore technology and operates a modern and versatile fleet of dredging and offshore-installation vessels that currently features over 90 MAN engines.
