A turbine-electric system is also possible using gas turbine generators. Some yachts use only gas turbines for integrated electric propulsion without any diesel engines. If electric propulsion is used via electric motor on shaft, or integrated into the main reduction gear driving the shaft, greater power available is realized faster than using ...
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through 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 internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller.
Oceanvolt is a Finnish boat electric motor manufacturer founded in 2004 by Janne Kjellman. The company was formerly known as Electric Ocean. Oceanvolt is headquartered in Vantaa, Finland. The company currently produces two types of propulsion systems for electric boats: saildrives and shaftdrives.
Yamato 1 on display in Kobe, Japan.The first working full-scale MHD ship. A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics.
Electric power for the propulsion motor is conducted through slip rings that let the Azipod unit rotate 360 degrees about the vertical axis. [8] Because Azipod units utilize fixed-pitch propellers, [ 9 ] power is always fed through a variable-frequency drive or cycloconverter that allows speed and direction control of the propulsion motors.
The reduced weight and footprint of the installed electrical equipment will vary depending on the ship type and application. One comparison using the DC distribution system instead of the traditional AC system for a Platform Supply Vessel (PSV), reduced the weight of the electrical system components from 115,520 kilograms (254,680 lb) to 85,360 ...
