Wang, S. and Guedes Soares, C. (2015), “Experimental and numerical study on bottom slamming probability of a chemical tanker subjected to irregular waves”, Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A. (Eds.), Taylor & Francis Group, London, UK, pp. 1065-1072
The probability of slamming occurrence of a chemical tanker subjected to irregular waves is numerically and experimentally studied. It is considered that slamming occurrence is dependent upon two conditions: the relative vertical motion at the same longitudinal position of the ship being larger than the vertical distance from the still water to the concerned position, and the entry velocity exceeding some threshold velocity. Model tests are performed to study the ship motions under irregular waves and the wave elevations are measured on several positions. In this paper, three irregular sea states are considered and adopted to a numerical procedure based on strip theory. The numerical ship motions are calculated in time domain and compared with the experimental data. The probabilities of bottom slamming for several ship bow sections are calculated and compared with the experimental data. Under different sea states, the slamming probability distributions along ship length are estimated with the numerical code.
