The MAN Diesel SE is a subsidiary of MAN SE, based in Augsburg . It merged with MAN Turbo AG on January 1, 2010 to form MAN Diesel & Turbo SE. Among other things, the world's largest and most powerful diesel engines are produced, mainly used as propulsion systems for ships , but also in power plants. In Hamburg, the MAN Diesel engine plant in Hamburg serves as a workshop for ship engines, which are serviced, overhauled and repaired there.
history
MAN Diesel has a long tradition in diesel engine construction. Rudolf Diesel completed the first diesel engine in the Augsburg plant of the then Maschinenfabrik Augsburg-Nürnberg AG in 1897 .
The Danish subsidiary Burmeister & Wain , based in Copenhagen , was acquired in the 1980s. Other diesel manufacturers have since been taken over, including the Danish Alpha Diesel Frederikshavn . Until September 1, 2006, the company operated under the name MAN B&W Diesel AG . On July 14, 2009 the merger with MAN Turbo AG to form the Power Engineering division was announced. The merger was completed on March 26, 2010 (retroactive to January 1) with the entry of MAN Diesel and Turbo SE in the Augsburg commercial register .
Products
The plant in Augsburg designs and produces diesel engines for ship propulsion systems and power plants with an output between 430 kW and 97,300 kW. Them by truck are delivered heavy transport to Neckar - Port Heilbronn .
MAN supplies complete drive systems with gearboxes and propellers. The Danish subsidiary in Copenhagen designs two-stroke diesel engines that are mainly used as the main engines of ships. They are built all over the world, but primarily in Asia ( Japan , Korea , China , Vietnam ) according to Danish engineering and sample drawings. The largest engines have come from Korean shipyards for many years. For many years these were in-line engines with seven, eight and nine cylinders, later twelve and fourteen cylinders with up to 97,300 kW drive power were also available. These engines only differ in performance, number of cylinders and overall length. Their cross-section and the components were always the same in a strict modular system .
The bore of the largest engine series, the K108, was 1080 mm, the stroke 2660 mm, which means that such an engine with a height of over 14 meters and a width of around seven meters and lengths of up to 32 meters requires space, comparable to a single-family house or a duplex. This type of engine weighs 2800 tons and delivers its maximum output at a speed of 97 revolutions per minute. Its diesel consumption is low in the variant as L2 (reduced peak power with 162 g / kWh). B&W engines were also built in the PRC .
The specialty of the German part of the company were medium-speed four-stroke diesel engines. At the time of the company merger, the largest engine was an eighteen-cylinder V-engine with 22,600 kW. MAN was also able to deliver in lower performance classes with four-stroke drives; the product range reached down to engines of around 430 kW. The smallest four-stroke engine had a bore of 160 mm and a stroke of 240 mm. The underlying market segment, such as for truck engines, was covered by the sister company MAN-Motoren .
The controllable pitch propellers built by MAN had a diameter of up to 7.3 m and a weight of up to 77.2 tons.
Scope of consolidation
MAN Diesel SE was the parent company of the subgroup (MAN Diesel Group), which consisted of manufacturing companies for ship engines , ship propellers , turbochargers , diesel generators and power plants .
The main consolidated investments of MAN Diesel SE were:
- MAN Diesel SE, Copenhagen, Denmark
- MAN Diesel Ltd, Stockport, Great Britain
- MAN Diesel SAS, Villepinte, France
- MAN Diesel (Singapore) Pte. Ltd., Singapore
- MAN Diesel Australia Pty. Ltd., Sydney, Australia

Others
For a series of five container ships, the model ship of which is the COSCO Guangzhou , MAN Diesel SE developed the first diesel engine with over 100,000 PS (73,500 kW) under the name K98 MC in 2006 . A variant of this, the 14K98MC7 with 116,875 PS (87,200 kW), was the most powerful marine engine in the world in 2008, but was not yet installed at the time.
The Lindanger product tanker, built in 2016 , is one of the world's first ships to run on the environmentally friendly fuel methanol . Four of a series of seven new product tankers with methanol as an alternative fuel were built by Hyundai Mipo Dockyard Co., Ltd (HMD) for the Norwegian shipowners Westfal-Larsen and Marinvest. The dual-fuel main engines of the type B&W 6G50ME-9.3 LGIB with a nominal output of 10,320 kW at 100 rpm are driven with methanol and marine diesel oil (MGO) as ignition oil. They were developed by MAN B&W and built by the engine and mechanical engineering department at Hyundai Heavy Industries.
