The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by the Finnish manufacturer Wärtsilä.It is designed for large container ships that run on heavy fuel oil.
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.
The electric power produced by the main engines and generators was transformed into propeller thrust by three large DC motors coupled to the propeller shafts. The centerline propulsion motor, located in a separate compartment, was a tandem unit consisting of two 5,500 hp motors while the port and starboard propulsion motors, located side by ...
The shaft power from each can either go directly to the propeller, pump jet or other mechanism, or it goes through some form of transmission; mechanical, electrical or hydraulic. In the 1800s, steam was one of the main power sources for marine propulsion.
They were later on replaced with 6-cylinder Wartsila engines that ran on heavy fuel oil (bunker C) the same as the main engines. Shaft generators were fitted so that when running at cruising speed these generators produced a large amount of electrical energy, which made these ships more fuel efficient. Safmarine was acquired by Maersk Line in ...
A primary shaft carries the compressor and its turbine which, together with a combustor, is called a Gas Generator. A separately spinning power-turbine is usually used to drive the rotor on helicopters. Allowing the gas generator and power turbine/rotor to spin at their own speeds allows more flexibility in their design.
