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 ...
Voith Schneider Propeller. A Voith Schneider Propeller (VSP) is a practical cyclorotor that provides instant thrust in any direction. There is no need to turn a propulsor. Most ships with VSPs do not need or have a rudder.
The device is different from the Voith-Schneider marine propulsion system (also mechanically linked), which can also quickly change the direction of thrust, as the Z-drive uses a shrouded conventional screw that pivots or rotates the propeller, unlike the variable-geometry blades of the Voith-Schneider.
VoithâSchneider propeller. The Voith Schneider Propeller, also known as a cycloidal drive is a specialized marine propulsion system. It is highly maneuverable, being able to change the direction of its thrust almost instantaneously. It is widely used on tugs and ferries.
She was the first British vessel driven by Voith Schneider propulsion units. [1] Throughout the war, she was on the Lymington-Yarmouth service on the Solent. A slab of concrete placed above her wheelhouse offered some protection against an airborne attack. By 1972, Lymington was too small for her owners' needs. The arrival of new ferries led to ...

In 1927, the Viennese engineer Ernst Schneider and the Voith company in Sankt Pölten applied jointly for a patent for the Voith Schneider propeller, which had been developed the year before based on the former's plans. This marine propulsion system, which also acts as a steering device, allows maneuverability previously impossible.
A typical DP set-up for a PSV is two thrusters located at the bow of the vessel which can be supplemented by two azimuth thrusters or Voith Schneider Propellers located at the stern. All modern PSVs are DP2 rated, meaning that there are two levels of redundancy in the DP system.
