Voith Turbo is introducing several products targeting efficiency and lower emissions.
A new electric Voith Schneider Propeller (eVSP), Voith meets the rising demand for resource-saving and energy-efficient mobility concepts for maritime applications. The new system combines the proven VSP technology with the electric know-how from the Voith Inline Thruster. The result is high efficiency and lower complexity, as the permanent-magnet synchronous motor is integrated into the propeller. Another advantage is provided by the complete elimination of a gearbox, which reduces noise to a minimum and frees up valuable space in the ship. The combination of propulsion and control in a single unit allows ships to maintain target position in rough waters. In addition, the VSP reduces ship roll, thereby increasing the comfort and safety of passengers.
Dr Dirk Jürgens, VP R&D, Voith Turbo Marine, said: “With the electric Voith Schneider Propeller, we are making an important contribution to the electrification of the drive train in marine applications and thus to even more resource-saving shipping. The new eVSP was developed for all applications involved in the mobility transition, for example, offshore ships, tugboats and ferries.”
A further variation on the VSP design is the rcVSP, or remote-controlled Voith Schneider Propeller. This allows ship assistance and tugboat manoeuvres to be carried out remotely. The goal is to make the work of tugs safer and more efficient. These vessels often work in dangerous conditions, operating right in front of the bows of the ships, which are often well over 300 meters long and 45 meters wide. Extremely high forces, which can exceed 100t during dynamic manoeuvres, are exerted on the towlines. Even minor technical problems or manoeuvring errors can lead to a line breaking or a collision between a huge oceangoing vessel and a tugboat. With the rcVSP, tugs can work without crews, with all manoeuvring from a shore-based control centre and towline handover accomplished automatically. The rcVSP contributes to minimising operating costs because with a remote-controlled tug, there is no need for crew facilities onboard. Sound insulation and even the bridge can be done away with, reducing weight and thus increasing manoeuvrability and reducing energy consumption.
The latest version of the Voith Schneider Propeller technology, the VSP X-type, concentrates on flexibility, hybridisation and reduced emissions. A higher power density and an optimised drive train result in lower fuel consumption and thus greater sustainability. The X-type features improved service-friendliness and optimised service intervals, maintaining the benefits of the VSP concept.
