Diesel Electric Yacht Propulsion

Electric propulsion with controlled power from 0 rpm to full rpm makes for superior maneuvering performance.

Diesel electric yacht propulsion.

The diesel generator can also be located away from guests to reduce noise and vibration and placed in areas of the hull not normally used for engines or people. Oceanvolt systems are extremely low. Due to the ongoing effects of pollution environmentally friendly propulsion systems are being heavily evaluated. Diesel electrical propulsion becomes viable when the installed kw for propulsion approaches or is exceeded by the kw installed for other purposes.

Oceanvolt electric propulsion systems for multihull clean electric power propulsion systems. A typical siemens single engine twin prop diesel electric propulsion system is comprised of a permanent magnet three phase alternator powered by the diesel engine through a speed increasing gearbox two short circuit proof solid state power inverter modules two 3 phase permanent magnet prop drive motors associated prop drive gearboxes a control computer and a conventional appearing helm control station. Diesel electric systems are now lighter and less expensive. Instant power no warm up and quiet operation of an electric motor make for superior overall performance.

With a decade of experience and hundreds of diesel electric packages in operation globally cummins is one of the pioneers in diesel electric propulsion. From the naval architect s standpoint a diesel electric system allows the drive engine to be moved away from the end of the propeller shaft. This type of power plant is the remedy for highly polluting traditional forms of yacht propulsion. Depending on the size of your battery bank cruise at low speeds all day or faster speeds for a couple hours.

Electric propulsion maneuvering is superior performance to gas or diesel engine of higher rating. The convenience of electric power distribution makes it possible to optimally locate the primary power source i e. As soon as you start sailing you start recharging your batteries with electric yacht s adjustable regeneration. The cat hybrid propulsion system can be developed as stem to stern solution with a pair of primary diesel engines connected to the vessel s azimuth drives.

Diesel generators exclusive of consideration as to whether it is for propulsion thrusters or cargo handling purposes. Traditional electric propulsion systems have been heavy and cumbersome. As the propeller operates always on design pitch in low speed sailing its efficiency is increased when running at lower revolution compared to a constant speed driven cp propeller. Usually diesel electric propulsion plants operate a fp propeller via a variable speed drive.

Removing the diesel engine fuel tanks and exhaust system cleaning up greasy engine compartments and freeing up both weight and space below deck. Electric yacht electric propulsion systems are available in many sizes and are recommended for boats up to 60 and 45 000lbs. In addition to the diesel engines the cat hybrid propulsion system includes vfd controlled booster motors which are also tied to the azimuth drives.
