JULY 6, 2015 — A fisheries research vessel being built for the Shanghai Ocean University by China’s Tianjin Xingang shipyard will be the first fisheries research vessel world-wide to use the Voith Schneider Propeller (VSP) propulsion concept. It is also the first offshore order Voith has received from a Chinese customer.

The 81.6 m x 14. 2 m research vessel is equipped with two 28R5 ECS/234-2 Voith Schneider Propellers and has two electric motors with an output of 1,850 kW each. It reaches a maximum speed of approximately 15 knots. This top speed is ambitious, given the size and engine power of the vessel but was achieved by the Shanghai Research Institute design team in close cooperation with Voith.

Intense model testing was carried out. Voith delivered model propellers from Germany to the research institute where they were integrated in a scale model. Voith actively supported the comprehensive test stages, thus contributing to vessel hull optimization.

Calculations and adaptations of the vessel lines resulted in the required top speed of 15 knots being technically feasible. The customer was particularly convinced by the precise maneuverability of the research vessel provided by the VSP propulsion concept and the technically sophisticated roll stabilization (VRS).

Those responsible at the university made it clear from the very start of the project that the oceanographers who will be on board the vessel are not necessarily experienced seafarers. To ensure a certain degree of comfort, the owner therefore insisted on the intelligent Voith Roll Stabilization which compensates most of the vessel roll via the VSP.

The research vessel will be launched in summer 2016. Voith will deliver the two VSPs, two shaft couplings, the roll stabilization and the entire electronic control system including four control stands in spring 2016.
