ChineseMarine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or engine turning a propeller, or less frequently, in pumpjets, an impeller.

Propulsion of liquefied natural gas (LNG) ships is undergoing significant change. The traditional steam plant is losing favor because of its low cycle efficiency. Mediumspeed dieselelectric and slowspeed dieselmechanical drive ships are in service, and more are being built.Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or engine turning a propeller, or less frequently, in pumpjets, an impeller.
The first phase of the project performed by GTT, CMA Ships, a unit of CGM, and DNV GL showed "promising results with regard to the commercial competitiveness of the design compared to an LNGfuelled ship with a conventional propulsion system," DNV GL said in its statement.ABB Friday announced that it, along with OMT and Solar Turbines, has joined Gaztransport & Technigaz S.A. (GTT), CMA CGM S.A. (CMA CGM), CMA Ships, and DNV GL for phase two of the PERFECt project, which is set to examine the technical concept and the commercial feasibility of using a combined gas and steam turbine system (COGAS) to power an ultra large container vessel (ULCS).

"The impulse behind this study was our interest in seeing how a modern ultra large container ship design could benefit from utilizing COGAS, which is a system for combined gas and steam turbine power generation," adds Gerd Würsig, Business Director for LNGfuelled ships at DNV GL – Maritime.The concept of using a combined gas turbine and steam (COGES) plant for merchant vessels, and LNG carriers in particular, was first announced by GE at The Motorship's 2013 Gas Fuelled Ships conference and featured in our December issue.The concept is claimed to offer low life cycle cost, high environmental performance and flexible design.

Gerd Würsig, Business Director for LNGfuelled ships atof ships where the engine efficiency is known to be around 52%. The high power density and the modularity of COGAS plants, together with the electric propulsion concepts, lead to additional container slots. This makes up for the slots which are lost by the higher space requirements for LNG as fuel compared to HFO as fuel.
