The development of a real-time deterministic decision support system (DSS) prototype (TRL7: prototype in use) is the objective of this research project. At the end of the project, a technology leap should be achieved to the extent that the real-time application of the DSS prototype can be demonstrated in an offshore operational environment with respect to sea state but also motion prediction.

The basic concept of the DSS is based on the continuous acquisition of the stochastic sea state by means of an (on-board) radar system. The temporal and spatial evolution of this sea state and the resulting structural motions are calculated using sophisticated numerical methods. A prediction - the view into the future - is only possible if the simulation results, i.e., the predicted wave at the structure as well as the structure response, are available well in advance of the arrival of the physical wave system. For the objective of the project, efficient as well as sufficiently accurate numerical methods are crucial for a successful deterministic prediction. Consequently, a real time prediction by using very fast computational methods, a prediction in real time (large prediction period) with simultaneously high prediction quality shall be achieved.

To achieve the overall objective, the project can be divided into the topics "non-linear wave inversion", "non-linear sea state prediction" and "motion prediction", which are finally combined in the topic "decision support system". The planned scientific work comprises novel and complex nonlinear methods representing a technological leap in terms of accuracy compared to the established linear methods. As a result, by using very fast calculation methods, a prediction in real time (large prediction period) with simultaneously high prediction quality is to be achieved.
