MAN B&W Diesel
From Wikipedia, the free encyclopedia
The MAN B&W Diesel Group is a supplier of large diesel engines for marine propulsion systems, stationary power supply and rail traction. The Group is also one of the leading suppliers of diesel power plants and turbochargers. The turnover in 2004 amounted to over €1.4 billion.
MAN B&W Diesel is a subsidiary of the German multi-national MAN AG corporation since 1980 when MAN acquired the Burmeister & Wain Danish shipyard and diesel engine producer headquartered in Copenhagen. The company still maintains operations at three main sites in Denmark for manufacturing, servicing, and licensing of its two-stroke engines and complete propulsion systems.

[edit] History
Burmeister & Wain was a large established Danish shipyard and leading diesel engine producer headquartered in Copenhagen. Founded by two Danes and an Englishman, its earliest roots stretch back to 1846. Over its 150-year history, it grew successfully into a strong company.
[edit] Foundation
Hans Heinrich Baumgarten (1806-1875) was from the town of Holstenbech near Pinneberg, in Schleswig-Holstein, an area of Germany that was then part of Denmark. He was apprenticed as a coffin maker by a farmer whose livestock he cared for. Later he was a carpenter before becoming a machine minder at the Danish newspaper Berlingske Tidende, whose printing office he later worked for in Berlin.
After trying to start a business with different partners, while in Berlin he was allowed an audience, on the subject of establishing a business in Copenhagen, with Crown Prince Christian of Denmark who was visiting. Shortly thereafter, in 1843 he was granted a Danish Royal Charter and what would later become Burmeister & Wain was launched with the opening of a mechanical workshop in Copenhagen.
[edit] Earliest years
Carl Christian Burmeister (1821-1898) was born into poverty. The son of a cook and restaurant keeper, he studied at the Polytechnical Institute in Copenhagen from 1836-1846, now the Technical University of Denmark. He had been awarded a scholarship abroad after recommendation following an assistantship to Hans Christian Ørsted who was director there at the time. Burmeister joined the H.H. Baumgarten Company in 1846, which became a partnership with the opening of its engineering works, and was renamed B&B.
Soon came the establishment of the B&B foundry in 1847, the delivery of its first steam engine in 1848, the renting of the Jacob Holm Shipyard at the 'Englishman's Place' in 1851, and the delivery of their first ship S/S Hermod in 1854, before Baumgarten retired from regular duties in 1861. With Baumgarten as a co-owner, in 1865, William Wain (1819-1882) joined what then became B&W. In 1872 the company became A/S B&W (Aktieselskabet Burmeister & Wain), a limited liability corporation. That same year saw the founding of the Refshale Island shipyard. At this point, Baumgarten, as the first founder, became a director of the board of what he would see become Burmeister & Wain Maskin- og Skibsbyggeri (Engineering and Shipbuilding) in 1880. Wain, from Bolton, England had apprenticed as an engineer in his youth and come up through the trades. He had worked for the Royal Danish Navy and the Royal Dutch dockyards. He came to have several designs to his credit within the company and his ingenuity was seen as "instrumental" in establishing its reputation.
[edit] Growth and development
Production of stationary paraffin engines began in 1890. Then, in 1898, a year after introducing it to the world, Rudolf Diesel granted Burmeister & Wain A/S exclusive Danish manufacturing rights for the diesel engine. A test engine was built that same year. The 1903-1904 year saw delivery of their first diesel engine to the N. Larsen Carriage Factory. 1911-1912 saw the world's first ever ocean-going diesel-powered ship, M/S Selandia, start her maiden voyage from Copenhagen to Bangkok with two B&W four-stroke main engines (furnishing a total of 2,500 hp).
The larger Teglholmen iron foundry was established in the 1920-1921 year to provide capacity for growth in the coming years of business acquisition. The first B&W two-stroke diesel engine set off to sea in 1930 and the world's largest diesel engine at the time was delivered in 1933 to H. C. Ørsted Power Station. Steady progress and consolidation continued through the period of World War II and the subsequent period of reinvigorated prosperity. The first turbocharged two-stroke diesel engine was commissioned in 1952 with larger and more innovative designs to follow.
By this point, the company's engines and licensed designs were used worldwide throughout the industry.
[edit] Recent adjustment and recovery
Meanwhile, post-war east Asian economies began to emerge as an industrial force. At the end of the 1960s and especially in the 1970's global competitive pressures, particularly from the far east, began to take their toll
In 1971, the shipyard and the engineering works were split into two independent companies. A more challenging period ensued until the 1979-1980 year when B&W Diesel A/S was established, and its shares were sold to MAN, of Germany. Though engine production at Christianshavn was later discontinued in 1987, successful engine programs were rolled out. At Teglholmen in 1988 a spare parts and key components production factory was established as was an R&D Centre at the same site in 1992. Though all Copenhagen operations were consolidated at Teglholmen in 1994 and the last volume production unit at the B&W Shipyard was delivered in 1996, in 2000 MAN B&W Diesel two-stroke diesel engines had over 70% market share, with a substantial number of MC-line engines on order.
The electronically controlled line of ME diesel two-stroke engines was added in 2002 with a maximum cylinder bore of 108cm. MAN B&W Diesel, Denmark, employed approximately 2,200 at the end of 2003 and had 100 million kW, or more than 8000 MC engines, in service or on order by 2004.
In 2006 the MAN group established a common European corporation called MAN Diesel SE
[edit] Locations
MAN Diesel has production places at Augsburg, Hamburg, Copenhagen, Frederikshavn, Pielstick and Stockport. The Stockport site was formerly known as Mirrlees Blackstone Limited.
