www.wartsila.com Wärtsilä Oyj Abp ( Finnish: [ˈʋærtsilæ] ), trading internationally as Wärtsilä Corporation , is a Finnish company which manufactures and services power sources and other equipment in the marine and energy markets.
Turbo-electric transmission uses electric generators to convert the mechanical energy of a turbine (steam or gas) into electric energy and electric motors to convert it back into mechanical energy to power the driveshafts. An advantage of turbo-electric transmission is that it allows the combination of high-speed turbines with slow turning ...
The first Azipod unit, installed on the Finnish fairway support vessel Seili in 1990, is now displayed at the Forum Marinum maritime museum in Turku, Finland.. In 1987, the Finnish National Board of Navigation made a co-operation proposal to the electrical equipment company Strömberg (later ABB) and the Finnish shipbuilder Wärtsilä Marine for the development of a new type of electric ...
Is the Wärtsilä-Sulzer RTA96-C used with direct drive or something else (gearbox? electric transmission?)? njh 06:46, 15 February 2006 (UTC) []. The usual installation of marine diesel engines in large commercial vessels like container ships or tankers is a direct connection to a fixed pitch propeller, no clutch, no gearbox, no nothing.
Shaft voltage occurs in electric motors and generators due to leakage, induction, or capacitive coupling with the windings of the motor. It can occur in motors powered by variable-frequency drives , as often used in heating, ventilation, air conditioning and refrigeration systems.
Five diesel generators together produce 20.8 MW, [37] giving a total electric output of 29 MW. [26] Two 9 MW electric motors augment the power on the 150 meter main propeller shaft, [37] the longest in the world. [39] Two bow and two stern thrusters provide port manoeuvrability, and two pairs of stabilizer fins reduce rolling. [37]
Queen Mary 2's power plant comprises four sixteen-cylinder Wärtsilä 16V46CR EnviroEngine marine diesel engines, generating a combined 67,200 kW (90,100 hp) at 514 rpm, and two General Electric LM2500+ gas turbines, provide a further 50,000 kW (67,000 hp); these drive electric generators, which in turn provide the power to drive four 21,500 kW ...
