Samenvatting

In the nineties the Delft University of Technology (TU Delft), faculty Maritime Technology (MT), department of hydromechanics, and the RNLNC, nautical sciences department, led by professor J.A Spaans, explored the possibility of determining the coefficients from full-scale sea trials. As a starting point the model by Inoue was used. But, this model has some drawbacks if the values of the coefficients have to be calculated from full-scale sea trials.The drawbacks have led to two research questions namely:1. Is there a basic model that can simulate basic manoeuvres of normalships with sufficient accuracy and which is valid and useful for awide range of speeds and rudder angles?2. What is the optimal method to calculate the values of the coefficientsof such a model, based on data derived from full-scale sea trials? For surface ships both these research questions can be answered more or less in the affirmative. Some time ago the navigation department of the NLDA was facing the question whether a mini-submarine, in this case of the type Autonomous Underwater Vehicle Remote Environmental Measurement Units (AUV RE-MUS), the same basic model can be used and whether in the same way the coefficients of the model can be estimated. The answer to these questions is given in this article.
