| Abstract | In the last three years, the Institute for Ocean Technology (IOT) and Memorial University of Newfoundland (MUN) have joined together to establish motion profiles of the Newfoundland fishing fleet. Eventually, the objective is to develop and validate a numerical tool, called MOTSIM that will be used to evaluate the number of Motion Induced Interrupts (MIIs), or any other similar parameter, and their impact on crew safety. So far, this involved conducting sea trials of representative vessels of the fleet and corresponding model tests in the wave basin for the smallest of them. In parallel, MOTSIM has been further developed and validated using the full scale and experimental results. This paper discusses numerical challenges encountered in simulating these trials and the model test, and reviews the methods developed to overcome these challenges. Comparisons between the numerical simulations and the full scale trials are presented. The simulations are also compared with the model tests results. Based on the results of this study, the numerical simulations seem to correlate reasonably well with the trials and the experiments. Sample MII values for some fishing vessels are also presented. |
