Daewoo Shipbuilding & Marine Engineering Co., Ltd. (DSME) of Korea, one of the world’s largest shipyards, has ordered four common-rail 12V48/60CR Tier-II propulsion engines from MAN Diesel & Turbo SE. The prime movers will power a new RoPax ferry for Tunisian ship owner COTUNAV (Compagnie Tunisienne de Navigation). The ferry will have a capacity of 3,200 passengers and 1,060 vehicles, and a top speed of 27.5 knots. At 210 × 30 m, the vessel will be the world’s largest ferry and contain a shopping centre, restaurants, swimming pool and multiple entertainment facilities.

MAN Diesel recently retrofitted the M/F Geisnes pendulum ferry’s engine to Tier II limits. This retrofit solution achieves a 30% NOx reduction. The MAN 6L23/30 main engine originally installed in M/F Geisnes was built in Frederikshavn, Denmark, in 1988 - and after the delivery of the ferry in 1989, it has served the vessel for 96,842 operating hours. In connection with the major overhaul of the main engine, it was decided by the Norwegian owner, Namsos Trafikselskab, to retrofit an upgrade package with Tier II engine components.
