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.

The turbochargers with VTA technology will equip the MAN B&W brand type 6S46MC-C low-speed engines aboard the new tanker, Stena Progress. On the basis of earlier trials, they are expected to reduce fuel consumption by around 2-3% with parallel reductions in exhaust emissions. “We are always interested in new energy saving technologies,” noted Hans Norén, President, Concordia Maritime. “When approached by MAN Diesel about employing VTA we decided right away that this was something we wanted to participate in. Stena Progress is a 65,200 DWT shallow-draught ice class tanker of the P-MAX type under construction for Concordia Maritime at the Brodosplit shipyard in , where the main engines will also be built under license.
