Voith Schneider Propeller VSP

Voith Schneider Propeller VSP

The Intelligent Propulsion System for Safe Shipping

The Voith Schneider Propeller (VSP) combines propulsion and steering in one unit. This unique vessel propulsion solution was developed 90 years ago by Austrian engineer Ernst Schneider. Today, Voith Schneider Propellers are in use all over the world wherever precise, safe and efficient maneuvering is of the essence.

Wide range of applications

    Voith provides propulsion systems tailored to a wide range of applications

    The VSP principle

      The VSP principle is strikingly simple and fascinating at the same time

      With the VSP, magnitude and direction of thrust can be set steplessly and as necessary. A circular disk with movable and controllable blades installed at a 90 degree angle to the disk rotates at the vessel bottom.

      The magnitude of thrust is determined by the rotational speed of the disk; the blade angle determines the direction of thrust. VSP is a perfect propulsion system for precise maneuvering, even under adverse conditions.


        The open sea – both a valuable source of energy and an unpredictable force. A force that can only be mastered safely and efficiently with the best technology. A force that requires a connecting BRIDGE – with the innovative drive systems from Voith.

        Best DP Performance – Can be kept in the required position
        With the Voith Schneider Propeller and the Voith Inline Thruster, your ships can be kept in the required position even during very high waves, severe gusts of wind and strong currents.

        Reduced Fuel Consumption – Less energy
        As a result of its immediate and very accurate reaction to weather-related disturbances, the VSP needs considerably less energy during dynamic positioning. Owing to their high efficiency, Voith propellers need significantly less fuel during transit and DP than comparable drives.

        Increased Comfort – Maximum comfort
        Ships with VSP drives ensure improved on-board well-being, as the danger of seasickness is reduced by the Voith Roll Stabilization, and because the Voith Inline Thruster ensures maximum comfort in terms of noise and vibration.

        Downtime Reduction – 15 more operating days
        Where other ships give up, VSP-based transfers can still be carried out. This means up to 15 more operating days per year due to the unique VSP force adjustment and the Voith Roll Stabilization.

        Great Productivity Under All Conditions – 25% more transfers
        The fast connection enabled by the VSPs even allows up to 25% more transfers within the same time frame.

        Effective, Innovative and Successful Offshore Solutions – Over 30 ships operating successfully
        Since 2007, Voith has been looking back on over 30 ships operating successfully in the challenging offshore market – worldwide.

          iVSP: Controlling a virtual Voith Schneider Propeller

            With the help of the iVSP (Interactive Voith Schneider Propeller) program you can experience for yourself how a Voith Schneider Propeller (VSP) actually works.

            iVSP 2.1

            We’ve completely redesigned the iVSP app and added features that make the Voith Schneider Propeller even more realistic in 3D.

            In Version 2.1, the standard ship is a double-ended ferry, which you control with virtual joysticks. The double-ended ferry has four propellers. You control the two fore propellers with the left joystick and the two aft propellers with the right joystick.

            In addition, Version 2.1 offers a completely new training mode. A typical docking procedure is simulated by positioning the ship in a marked field within a specified time.

            Other new features include:

            • The user interface now has updated functionality that makes the iVSP app easier to use.
            • Steer like the captain of a VSP tug in the new Free Driving Mode. You can try out the maneuvers that are possible with this innovative drive.
            • Are you skilled enough to drive a VSP tug? Find out and master the course in Simulation Training.
            • Compare your results with friends and colleagues on the high score list.
            • Switch at any time from 3D into the views that show the motion or hydrodynamic forces. These show exactly what happens when you operate the VSP in real life.

            Download the latest version of the iVSP application and discover new features!

            iVSP 2.0

            iVSP 2.0 invites you to be your own captain and explore the unique technology of the Voith Schneider Propeller (VSP).

            The VSP is the safest and most accurate drive system for ships; thrust can be varied extremely fast, steplessly and precisely in all directions.

            Perhaps you still remember the predecessor program iVSP? It certainly helped to explain the VSP technology, but the ship sailed without illustrating the complex physical effects. With the new version, you get a quasi-realistic on-board experience of the advantages of the VSP and also gain a 3D insight into the heart of the VSP – its kinematics.

            The iVSP 2.0 program has three menu points: “Free Driving Mode”, “Kinematics & Forces” and “Active Simulation Training.”

            The vessel you will find under the “Free Driving Mode“ and “Active Simulation Training“ menus are ready to sail and depicted as realistically as possible. The forces of the VSPs, the hydromechanics of the ship and all inertia effects are accurately captured in a time simulation. In “Active Simulation Training“ range, you can test your steering capabilities of the VSP by operating the ship in competition with other captains.

            Under “Kinematics & Forces“, you learn how the unique mechanics and hydromechanics of the Voith Schneider Propeller work. Take your time: Alternate between “Kinematics“ and “Hydrodynamic Forces“; modify the speed, longitudinal and transverse thrust; and monitor the movements of the kinematics and/or the generation of hydrodynamic forces. Witness how the secret of the VSP is being revealed.

            We wish you a great time on board - Voith Turbo Mobility.


            Controlling a virtual Voith Schneider Propeller

            "I hear and I forget; I see and I remember; I do and I understand." In full accordance with this quotation by Confucius, Voith Turbo Schneider Propulsion has developed the iVSP (Interactive Voith Schneider Propeller) program in English and German. With the help of this program you can experience for yourself how a Voith Schneider Propeller (VSP) actually works.

            Viewers can play captain by using their mouse to control an on-screen steering wheel and lever or, alternatively, an on-screen joystick. The virtual VSP reacts immediately and visibly to any change in rudder or driving pitch. A kinematic or hydrodynamic viewing option illustrates the actual VSP operation. The relevant forces are shown by arrows in different colors.
            The maneuvers performed by the ship are displayed in the upper right hand part of the screen. A Voith Water Tractor (VWT) can be watched during its maneuvers from a bird's eye perspective (a camera linked to the VWT). The compass in the right-hand corner indicates the sailing direction.
