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.

Diesel electric marine propulsion systems.

Compared to direct diesel drives diesel electric propulsion systems are technically and operationally superior in virtually all applications. Drive mv is the marine industry s leading alternating current propulsion system. 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.

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. The difference is experience. The conventional propulsion system of the ship is efficient but requires high operating costs and increases the marine pollution. Although it can unleash much power it runs as quiet as a whisper with low vibration.

Electric propulsion system overview a propulsion system that outrivals conventional propulsion engines in efficiency and functionality. This superiority has been a major reason for the steadily growing demand for diesel electric main drives in marine engineering applications. In order to meet the challenge of high operating cost and marine pollution ships propulsion system have changed from conventional power system to electric propulsion system. 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. 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.
