In Chapter 2 the theory of the computational methods SEAWAY and SWAN are described. The performed calculations with SEAWAY on the IMS hull series are described and the results of the SWAN calculations are presented. The experiments that were performed for this study are described in Chapter 3. A description is given of how the linesplan of the models were calculated and the experimental setup is discussed. In Chapter 4, the validation of SEAWAY with the experiments is presented as well as the comparison of the results of SEAWAY and SWAN and the heeling angle discussion is presented. The results of the comparison and validation are discussed and some conclusions are presented. In Chapter 5, the added resistance calculation in the VPP is examined. The polynomial formulations that are used in the VPP to calculate the added resistance are compared to SEAWAY based formulations and besides the SEAWAY formulations are validated with the experiments. The results are discussed and two possible improvements of the VPP are presented. In Chapter 6, VPP calculations on a test fleet with the possible improvements are compared with the original VPP and a benchmark. Finally, in Chapter 7, the conclusions are given.
