STRENGTH OF SHIP BOTTOM IN GROUNDING, 1ST REPORT: AN INVESTIGATION INTO THE CASE OF A SHIP STRANDED ON A ROCK

The behavior of double bottom structures is studied through model tests for two types of grounding. On the first type, a ship runs on a rock that penetrates through the bottom plate. In the other type, a ship strikes a rock and suffers the intrusion of the rock into the double bottom from the forepart of the ship. The test results for the first type are compared with results obtained using a nonlinear finite element program. It is demonstrated that the finite element method represents a useful tool for the analysis of load-rock penetration curves of double bottom structures. In addition, through a simplified analytical procedure, the height of double bottom required to protect the inner bottom plate from rock penetration is examined in a usual tide range.
