A.P. M?ller orders MAN diesels

MAN Diesel has received the first order for its 7K80ME-C, Mark-9 engine.

Hyundai Heavy Industries (HHI) will build four such engines for the A.P. M?ller Group, intended for container ships to be constructed by the Korean Hanjin Group.

The K80ME-C Mark-9 engine is extremely competitive in terms of production costs and cost per kW and represents a comprehensive update of its Mark-6 predecessor with boosted power and adopts a number of design features also shared by the S65ME-C engine.

Mean effective pressure is set at 20 bar, with maximum firing pressure at 160 bar. At 104 r/min and a mean piston speed of 9 m/s, the K80ME-C9 yields a power per cylinder of 4,530 kW/cyl. Cutting-edge, well-proven design features will be used during construction of the K80ME-C9 engines to reduce production costs while maintaining maximum reliability and lengthy intervals between overhaul. These include an optional, welded cylinder-frame that offers increased rigidity at lower weight, an Oros combustion chamber that contributes to low wear-rates and good scuffing resistance, and the choice of an engine-driven or electronic oil-supply design. Distance between cylinders is also reduced, making the 7-cylinder Mark-9 engine approximately a half-metre shorter than the Mark 6.

Impressively, the 7K80ME-C9 matches engines of a higher bore in terms of power output per cylinder. It also comfortably meets emission and noise regulations as stipulated by the IMO, displaying flexible emission characteristics with low NOx and smokeless operation.
