Diesel Electric Marine Propulsion Systems

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 pump jets an impeller.

Diesel electric marine propulsion systems.

Electric propulsion system overview a propulsion system that outrivals conventional propulsion engines in efficiency and functionality. Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. Drive mv is the marine industry s leading alternating current propulsion system. This article covers the two main types of electrical drive systems currently in use frequency controlled a c motors and scr controlled d c motors and gives you a clear picture on the layout of the diesel electric marine propulsion systems.

Among all the prospective alternate power sources electrical propulsion system is one of the best tried out alternative in today s time. This superiority has been a major reason for the steadily growing demand for diesel electric main drives in marine engineering applications. Compared to direct diesel drives diesel electric propulsion systems are technically and operationally superior in virtually all applications. In case of conventional propulsion system the propeller is driven by main engine which is running on heavy oil and in addition to it we were having another diesel driven alternator to take care of other loads so these.

The difference is experience. In conventional power system arrangements the ship s propellers are driven by a diesel propulsion engine while the supply of electricity for the other shipboard loads is transmitted via the shipboard generators. Marine engineering is the discipline concerned with the. The conventional propulsion system of the ship is efficient but requires high operating costs and increases the marine pollution.

Diesel electric propulsion systems are clearly superior both technically and in operation to normal diesel drive systems in almost all areas. Recent renewed interest in diesel electric marine propulsion creates a need for more understanding of how the systems work and how they are laid out.
