Grounded ship faces up exceptionally different stability forces unlike in her normal operating condition. This critical situation must be corrected as soon as can minimize hull stress, the risk of pollution and stability failure. Re-floating the ship need full understanding of the impact of ground reaction (R) on the ship buoyancy and stability. Re-floating the ship has different phases and there are several immediate actions that should be taken by ship's crew; one of these phases is re-calculation of ship stability conditions. In this paper, a guide to understanding the effect of the ground reaction (R), determines the amount of ground pressure and its location. With consideration of the seabed form whether symmetric of asymmetric. Calculating the magnitude of the ground reaction (R) using different applicable methods, explaining the effect of using weight to re-float the ship by her own means, focusing on GM calculation after grounding. 展开更多
