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 ...
Integrated electric propulsion – Arrangement of marine propulsion systems that generators generate electricity; Internal drive propulsion – Form of marine propulsion. Non-road engine – Internal combustion engine classification; Nuclear marine propulsion – Propulsion system for marine vessels utilizing a nuclear powerplant
An example of integrated electric propulsion in the Type 45 destroyer (GT: gas turbine; DG: diesel generator) Integrated electric propulsion (IEP), full electric propulsion (FEP) or integrated full electric propulsion (IFEP) is an arrangement of marine propulsion systems such that gas turbines or diesel generators or both generate three-phase [1] electricity which is then used to power ...
In March 2021, Busek and Maxar Technologies completed an end-to-end hot fire test campaign validating the 6-kilowatt solar electric propulsion (SEP) subsystem for the Power and Propulsion Element (PPE) of NASA’s Gateway in lunar orbit. [24]
This type of propulsion system has a long tradition throughout the 1990s and today such propulsion units are produced by a number of companies around the world. [6] In the Azipod unit, the electric motor is mounted inside the propulsion unit and the propeller is connected directly to the motor shaft. [7]
The other is to provide the last 10 minutes or so of propulsion when the boat is in port and needs to be manoeuvred into a tight berth in a crowded and confined marina or harbour. Electric propulsion is not suitable for prolonged cruising at full power although the power required to motor slowly in light airs and calm seas is small.

Replenishment ships help allow the Marine Corps maintain a forward presence. Her primary mission is the delivery of supplies to enable the arrival and assembly of a Marine Expeditionary Brigade (MEB). The T-AKE transfers cargo – ammunition, food, fuel, repair parts, ship store items and expendable supplies to Marine and joint forces ashore.
