Headquarters in Helsinki

Wärtsilä is a Finnish corporation which manufactures and services power sources and other equipment in the marine and energy markets. The core products of Wärtsilä include large combustion engines. The company employed 17,528 workers in more than 70 countries at the end of 2010, and its headquarters are located in Helsinki.


Marine market

Wärtsilä powers every third ship, and services every second ship sailing the world’s seas.[2]

The company services the merchant, offshore, cruise & ferry, naval, and special vessel markets globally, and the offering includes ship design, main and auxiliary engines, auxiliary power systems, electrical and automation packages, propulsors (such as water jets, thrusters, propellers and nozzles), seals, bearings, gears, rudders, scrubbers, boilers and all related services, such as repair, configuration, upgrading, training, maintenance and environmental services.

The environmental services range from reduction of air emissions, such as NOx, SOx, CO and VOC's, to oily waste water treatment and other water solutions.

Wärtsilä was an important Finnish shipbuilder 1935–1989, building e.g. cruiseferries and a large share of the icebreakers of the world. The shipyards are now owned by STX Europe.

Energy market

Wärtsilä is a leading provider of power plants in distributed and flexible power generation.[3]

Their product porfolio consists of installations up to 500MWs, running on most fossil fuels, such as diesel, oil, natural gas, fuel-oil, biofuel and liquefied natural gas (LNG). In addition for the reliability of traditional base power generation, the engines have the capability to start and stop quickly and they maintain their effiency in part load, which makes them well suited for peaking power production, smart grids and emergency power systems. They can also utilize the combined cycle and cogeneration to produce steam or hot water for heating, and trigeneration for chilled water, which can be used in e.g. air conditioning.

Wärtsilä also provides products and services for grid stability management, utilization of gas flares, pumping applications (such as pump and compression drives), financial services and project management services for projects concerning power generation.

In 2006, Wärtsilä delivered the Dr. Bird II, a 49.5 MW power barge, to accompany Dr. Bird I (delivered in 1995) in Jamaica. These barges produce in total 123.6 MW and are now owned by Jamaica Energy Partners.[4]


The Emma Mærsk is powered by Wärtsilä engines

Wärtsilä engines are mainly used for marine propulsion and for electricity generation. The engines that Wärtsilä produces range from the 4L20, a four-stroke, medium-speed engine producing 720 kW (970 hp), to the Wärtsilä-Sulzer RT-flex96-C two-stroke diesel engine series, which is considered the most powerful prime-movers in the world.[5] This model has a cylinder bore of 960 mm (37.8 in) and stroke of 2500 mm (98.4 in). The largest version produces up to 84,420 kW (114,800 bhp) in the 14-cylinder configuration. These engines are used to propel large container ships, such as those of the A. P. Moller-Maersk Group. The vessels are known as the E-class ships; Emma Maersk was the first.

Wärtsilä produces a full line of four-stroke medium-speed engines, many of which are multi-fuel capable (Diesel fuel, heavy fuel oil, vegetable oils, and natural gas), ranging up to the 20V46F, which produces 23,000 kW (31,000 hp) operating at 600 RPM.

Wärtsilä also offers a full line of two-stroke, low-speed engines, ranging from approximately 3860 kW (5,180 hp) up to 130,520 kW (175,030 hp).
