MAN B&W Diesel Introduces

Two More Large Bore Engines

Popular MC Engine Series Sales Rise

Orders for MAN B&W Diesel's

MC two-stroke series engines are on the rise, according to the company.

By mid-September of this year, the company reported that 1,246 MC low-speed engines with an aggregate output of 16,056,900 bhp (nominal) were on order or in service, with installations aboard vessels ranging in size from large fishing vessels to state-of-the-art containerships and

VLCCs.

MAN B&W Diesel has now intro- duced two more large bore model options—aimed at the container- ship sector—to the MC program.

The new models, designated

K80MC-C and K90MC-C, are spe- cial versions of successful 800-mm and 900-mm bore engines. The 12- cylinder K90MC-C engine raises the upper limit of the MC program to 67,080 bhp. The new versions offer shipowners and shipbuilders the same benefits as other MC en- gines—high reliability and low oper- ating and production costs.

Three 12-cylinder K90MC en- gines, each developing 64,320 bhp, have been ordered for a trio of large containerships which will be the most powerful single diesel-pro- pelled vessels ever commissioned.

Ten-cylinder, 900-mm bore engines, each with a maximum rating of 53,600 bhp at 90 rpm, were ordered for a series of nine containerships being built for Danish owner A.P.

Moller. The last three of these ships will be fitted with the 12-cylinder engines, though originally ordered with 10-cylinder engines.

The popularity of the MC series reflects the scale of its power range, one of the widest on the market.

Eight bore sizes ranging from 260 mm to 900 mm offer outputs from as low as 870 kw (1,190 bhp) to 49,320 kw (67,080 bhp). The operator's se- lection of an engine which most pre- cisely matches his newbuilding or retrofit project is enhanced by a choice of three different stroke-bore ratios—2.875:1 (K-models), 3.24:1 (L-models) and 3.8:1 (S-models)— and optimum individual layout flex- ibility.

The opportunity to maximize operating economy in integrated propulsion/auxiliary plants is also promoted by MAN B&W Diesel's development of the exhaust gas power turbine-based Turbo Com- pound System to boost the propul- sive or electricity generating effort.
