Feature 1 | DANISH MARINE INDUSTRIES Production shuffle for MAN Diesel
MAN Diesel plans to rely solely on licensees to deliver its two-stroke engine products, with restructured in-house production focused on boosting four-stroke capacity. Henrik Segercrantz outlines the consequences for its Danish arm.
I
n 2006 MAN Diesel decided to re- arrange its manufacturing divisions in order to create new resources for its
four-stroke business. Te decision was made to stop the in-house production of two-stroke engines altogether by 2009 and to build these engines entirely through licensees. MAN Diesel A/S operates at three locations
in Denmark. Its headquarters in Copenhagen includes a large R&D department and test centre, where new MAN B&W two-stroke engines are developed. Copenhagen also handles the group’s two-stroke licensing business, production of key components and spare parts, and the two-stroke engine service business. In Frederikshavn, MAN Diesel
manufactures smaller two-stroke marine engines up to the 50cm bore S50-series, in the 2000kW-12,640kW power range. Tis two-stroke production will phase out after 2009. MAN Diesel, Frederikshavn, also develops and manufactures complete propulsion systems for small and medium size vessels based on four-stroke engines, in the power range of 960kW-3060kW. Tese include engines, gearboxes, CP propellers, and remote control systems. Auxiliary marine and stationary generating sets are also produced, in the 450kW-4230kW power range. Frederikshavn also handles the sales and service of these propulsion systems. Te generating set sales and service is handled from Holeby. Production of four-stroke engines
is currently divided between plants in Augsburg, Germany; St Nazaire, France; and Fredrikshavn. To free up capacity for component manufacturing in Augsburg, the V-type 48/60B engine as well as the V- type 51/60DF dual-fuel engine for LNG carriers will, in the future, be assembled in France. Production of all four-stroke core components will take place in Augsburg, as will the assembly of the lightweight large- scale engines. Frederikshavn currently

manufactures MAN Diesel’s small-bore medium-speed engines with a cylinder diameter of up to 28cm and power up to 4MW. Te assembly and testing of the biggest four stroke engines, weighing over 200tonnes, will be done entirely in St Nazaire and, from 2009, in Frederikshavn, where the assembly and testing of the largest bore diameter 58/64- type engine will take place. Te aim of this re-allocation is to achieve
a significantly greater production volume at established locations. ‘This measure, as well as adjustments
to our four-stroke product portfolio, will create additional capacity,’ MAN Diesel chief
executive Dr Pachta-Reyhofen commented last year. Thomas S Knudsen was recently
appointed head of MAN Diesel’s two-stroke business unit. Based at MAN Diesel A/S in Copenhagen, he has taken over from Peter Sunn Pedersen, who will retire at the end of this year. Mr Knudsen previously headed the R&D department of MAN Diesel A/S, and this role has now been taken over by Søren H Jensen.
Two-stroke licensee Currently, there are 35 individual licensees of MAN Diesel engines and exhaust-gas
