96Maritime Reporter & Engineering News MAN Diesel & Turbo said its first super-long-stroke, 90-cm bore Mk 9 en- gine has completed test bed trials atHyundai Heavy Industries Engine & Machinery Division successfully. The S90ME-C9.2 covers the new trend in container shipping demanding smallerbore, super-long-stroke engines with lower propeller speeds. Physically it is the largest two-stroke engine ever designed by MAN Diesel & Turbo and will deliver a torque of 8.5 million Nm at 84 rpm. It has a total output of 69,720 kW. The engine has been built by one of world?s major two-stroke engine builders, Hyundai Heavy Industries, and it will be installed on a container vessel built at Samsung Heavy Industries for Orient Overseas Container Line (OOCL). The engine is in fact partly due to the global economic implosion of 2008 andcontinued economic malaise today, a development which has hit the con- tainer shipping sector hard. With this, shipowners continue to in- vestigate operating cost reductions, through measures like low-load opti- mization of engines, slow steaming and operation with turbocharger cut-out. These tendencies led MAN Diesel &Turbo to offer possibilities supporting optimized propulsion efficiency by way of lower propeller speeds by using longer-stroke engine designs. In the midst of economic turmoil,shipowners are expected to clean up their act, literally, as a mounting array of international initiatives, led by the new Energy Efficiency Design Index, EEDI, which has helped manufacturers such as MAN Diesel & Turbo to de- velop the MAN B&W super-long- stroke S90ME-C9.2. Developed specifically for container ships, the S90ME-C9.2 is based on theVLCC-optimized S90ME-C8, which inthe meantime also found applications ina number of container ships.Furthermore, the G series of engineswith even larger stroke to bore ratios, has been made available, with G40, G45, G50, G60, G70, and G80 type en-gines supporting the tendency of using lower propeller speeds with a super- long stroke for all ocean-going ship types.By using the low propeller speed sup- ported by the S90ME-C9.2 engine, theengine is delivered with the following three different MCR optimizations: 1)High-rated MCR with part load op-timization2)De-rated MCR optimization withpart-load tuning3)De-rated MCR optimization withlow-load tuning .FAST.
