The typical Offshore Support Vessel (OSV) is a twin-screw vessel. When the bollard pull is the most important operating parameter, the OSV is mostly equipped with controllable pitch propellers in nozzles. When manoeuvering and DP capabilities determine the design of the OSV, thruster and Voith Schneider Propellers (VSP) are used. The Voith Schneider Propeller can also be used for roll stabilisation and offers the optimum DP control of the vessel. Moreover OSVs are equipped in some cases with roll damping tanks. By these means, the OSV becomes a stable working platform in a stormy sea.

Within the framework of various research projects and industrial contracts [1], [2], [3] an extensive investigation of such ship propulsion, with VSPs or with thrusters, were performed. Thus the SVA Potsdam can offer options from a wealth of experience, for example regarding influence of the blade geometry or installation conditions. In addition to resistance and propulsion analysis, manoeuverability and seakeeping investigations for these vessels can be carried out at SVA Potsdam [4], [5].
