COGAS Propulsion for LNG Ships

Day 1 Fri, October 17, 2008, 2008
Propulsion of LNG ships is undergoing significant change. The traditional steam plant is losing favor because of its low cycle efficiency. Medium-speed diesel-electric and slow-speed diesel-mechanical drive ships are in service, and more are being built. Another attractive alternative is combined gas and steam turbine (COGAS) drive.

Propulsion of ships

Journal of the Franklin Institute, 1918
IT is doubtful if any branch of engineering has advanced as slowly and cautiously as that branch of marine engineering which has to do with the propelling of machinery . Reliability seems to have been the only thing in view, and economy seems, until very lately, to have received very little consideration .

Synchronous motors for ship propulsion

Journal of the American Institute of Electrical Engineers, 1921
SINCE the inception and development of the idea of electric ship propulsion, the question of the possibility of using synchronous motors for such service has often been raised. Such a motor could be designed for unity power factor with a resulting saving in cost, weight, and efficiency, of both motor and generator.

The autogyro for ship propulsion

International Shipbuilding Progress, 1983
A strip theory approach is described which is designed to obtain the lift and drag coefficients of a wind turbine rotor operating as an autogyro. This theory is an extension of the autogyro theory which was developed during the 1920’s and 1930’s. The theory has been extended to include the effects of varying blade planform, blade section and blade ...

The propulsion of ships by electricity

Journal of the Institution of Electrical Engineers, 1928
After a short introduction to the subject proper the conditions of service, i.e. the loading of generators, is reviewed, and this is followed by a few notes on the control of electrically propelled ships. A short description of the types of motors used is given, and this is accompanied by a mention of a few of the more interesting points in the ...

PERSPECTIVES FOR A WIND ASSISTED SHIP PROPULSION

International Journal of Maritime Engineering, 2018
For three different wind propulsion technologies, the energy saving potential of sea going cargo vessels are discussed: a kite, a Flettner rotor and a Dynarig-sail. The energy saving potential can be increased significantly if the route can be optimized when using a wind assisted ship propulsion.
