Example 1
Using the Simplified Stability Data shown in Figure 47.1,estimate the amount of cargo(Kg 3 m) which can be loaded so that after completion of loading the ship does not have deficient stability. Prior to loading the cargo the following weights were already on board: 250 t fuel oil Kg 0.5 m. Free surface moment 1400tm 50t fresh water Kg 5.0 m Free surface moment 500tm Kg 4.0m 2000 t cargo The light displacement is 1000 t, and the loaded Summer displacement is 3500 t
