Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems. V12 marine diesel engines . Human-powered paddles and oars, and later, sails were the first forms of marine propulsion. Rowed galleys, some equipped with sail, played an important early role in early human seafaring and warfares. The ...
The CODLAD propulsion system is based on the use of electric motors directly connected to the axes (generally two) of the propellers. The electric motors are powered by diesel generators and to have higher speeds, as happens in CODAD propulsion systems, the higher power diesel engine is inserted which is disconnected from the transmission system to return to cruising speed.
CODAG Water jet And Refined Propeller (WARP), a system developed by Blohm+Voss as option for their MEKO line of ships, also falls in this category, but avoids the above-mentioned problems. CODAG WARP uses two diesel engines to drive two propellers in a combined diesel and diesel (CODAD) arrangement, i.e. , both shafts can also be powered by any ...
Integrated electric propulsion (IEP or IFEP) For every propeller shaft there is one diesel engine for cruising speed and one geared gas turbine for high speed dashes. Both are connected to the shaft with clutches ; only one system is driving the ship, in contrast to combined diesel and gas (CODAG) systems that can use the combined power output ...

The first Azipod unit, installed on the Finnish fairway support vessel Seili in 1990, is now displayed at the Forum Marinum maritime museum in Turku, Finland.. In 1987, the Finnish National Board of Navigation made a co-operation proposal to the electrical equipment company Strömberg (later ABB) and the Finnish shipbuilder Wärtsilä Marine for the development of a new type of electric ...
The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...
