How to calculate block coefficient of a ship
WebThey found that this added mass coefficient varies during the collision and that the value is in the range may = 0.4 – 1.3. The coefficient depends on the hull shape, and it increases with the impact duration. However, if the collision duration is very short, the value may = 0.4 proposed by Minorsky may be a good approximation. WebFig. 5. Maximum ship squat against block coefficient at considered speeds The graph in figure 5 shows that for ships with block coefficient over 0.800, the greater the speed the bigger the squat is. On the other side, vessels with CB equal to 0.500 have small differences in squat dimensions for considered speeds. Fig. 6.
