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.
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.
In the Azipod unit, the electric motor is mounted inside the propulsion unit and the propeller is connected directly to the motor shaft. [7] 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 ...
The rim-driven thruster, also known as rim-driven propulsor/propeller (or RDP) is a novel type of electric propulsion unit for ships. The concept was proposed by Kort around 1940, but only became commercially practical in the early 21st century due to advances in DC motor controller technology. [ 1 ]
Savannah is a super-yacht built in 2015 at the Dutch Feadship yard in Aalsmeer. [1] The yacht blends a single diesel engine, three gensets, batteries, propeller, and azimuting pioneering electro-mechanical propulsion platform. This combination offers fuel savings of thirty percent. [2] [3] [4] It is equipped with a 1 MWh Battery from Corvus ...
The DC distribution system is simply an extension of the multiple DC links that already exist in all propulsion and thruster drives, which usually account for more than 80 percent of the electrical power consumption on electric propulsion vessels.
Principle of a CODLAG propulsion system. Combined diesel–electric and gas (CODLAG) is a modification of the combined diesel and gas propulsion system for ships.A variant, called the combined diesel–electric or gas (CODLOG) system, contains the same basic elements but will not allow simultaneous use of the alternative drive sources.
