The final goal of this research is to establish the relative dangerousness D∕B for factors on seakeeping performance. This D∕B is essential to develope the seakeeping performance evaluation system built-on-ship. The system is composed of the apparatus for measuring a vertical acceleration to be generated by the ship’s motions, computer for calculating the synthetic seakeeping performance index and monitor for displaying the evaluating diagram of navigational safety of ship. In this paper, a methodology on the establishment of the relative dangerousness D∕B for factors on seakeeping performance is presented by a numerical simulations, playing an important role on the algorithm of the program for calculating the synthetic seakeeping performance index. Finally, It is investigated whether the relative dangerousness D∕B can be realized an accurate values according to the loading conditions, weather conditions, wave directions and present ship’s speed of a model ship. |
