Good ship lines are the basis for the efficient and safe operation of a vessel. Clients of SVA are supported in the development of optimal ship lines by experienced engineers and the use of effective calculation tools. The design process takes place in close cooperation with the client and is accompanied by CFD calculations. With the results of the CFD calculations, a speed and performance prediction can be created. For lines development at the SVA Potsdam, the programs CAESES and DELFTship Professional are used. The CFD calculations are performed with the viscous CFD solvers ANSYS CFX and Fluent. In order to assess the seakeeping behaviour of a ship design, the SVA Potsdam uses the UTHLANDE program package.
If the main dimensions are not fixed, the SVA Potsdam provides parametric studies according to the prescribed specifications. By means of CFD calculations, statistical methods and the SVA database the best values for parameters such as main dimensions (L, B, T) or coefficient (CB, CM, LCB …) are hereby determined. From this, the impact of changes in various shape parameters can be determined on the performance of the vessel.
