Resistance And Propulsion

The prediction of the achievable speed of a vessel is the primary task of a ship model basin. In the 280 m towing tank, reliable performance predictions are developed by means of resistance and propulsion tests based on the recommendations of the ITTC. These are also carried out for the verification of the EEDI.

In the very early stages of a project, speed predictions can be calculated from comparison with similar ships or with empirical methods.

Exact performance predictions are produced by means of viscous calculation methods (CFD). CFD calculations are also the basis for form optimisation and development of ship lines, the optimisation of appendages (bilge keels, stabilising fins, shaft struts …) and the optimisation of propulsion systems.
