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 introduced two more large bore model options—aimed at the containership sector—to the MC program.
The new models, designated K80MC-C and K90MC-C, are special 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 engines— high reliability and low operating and production costs.
Three 12-cylinder K90MC engines, each developing 64,320 bhp, have been ordered for a trio of large containerships which will be the most powerful single diesel-propelled 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 selection of an engine which most precisely 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 flexibility.
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 Compound System to boost the propulsive or electricity generating effort.
The broad appeal of the uniflow scavenged MC program is emphasized by a number of significant propulsion plant installations in recent months. Among them was the 3,900- TEU Marchen Maersk, the first of A.P. Moller's 10K90MC-powered advanced containerships to enter service.
The other end of the power spectrum saw the seagoing debut of the S26MC design, the latest and smallest addition to the MC series, in the 126-TEU feeder containership Rokku Maru. The six-cylinder S26MC develops 2,185 kw (2,970 bhp) at 250 rpm.
Orders for the S26MC for newbuildings in China and South Korea, as well as a great deal of interest from European customers, suggest that the 260-mm bore design will increase the low-speed engine's penetration of the small-to-mediumsized ship sectors—a market already sucessfully targeted by the 350-mm bore MC models.
The larger bore MC models are well suited for "new generation" VLCCs now entering service, as well as other larger tankers and bulk carriers.
The 600-mm bore design remains a popular choice for mediumsized bulkers, tankers and containerships.
Besides the overall economy, reliability and durability engineered in to MAN B&W Diesel low-speed diesel engines, an operator's costs can be reduced further by using CAPA, the company's new computer-based performance analysis and maintenance control system. Consumers will also benefit economically from the introduction of CIM (Computer Integrated Manufacturing) by MAN B&W Diesel engine licensees.
Already, R&D and component simplification has reduced the number of production hours for an MC engine by around 20 percent as compared with earlier models, and assembly times have been cut even more significantly.
