Marine Electric Propulsion Engine

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.

Marine electric propulsion engine.

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. Electric propulsion system overview a propulsion system that outrivals conventional propulsion engines in efficiency and functionality. Diesel electric marine propulsion systems reduce fuel requirements increase maneuverability minimize environmental risks and make your ship quieter and more comfortable. 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.

Marine engineering is the discipline concerned with the. However their main advantage lies in the exceptional degree of fail safety that drive lv attains thanks to its redundant system design. 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. 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.

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.
