Abstract
To verify the effectiveness of Minorsky's formula that is used in the current regulation of ship with anti-collision structure, the simplified analysis based on the rigid-plastic analysis is developed. The collision of test ship with T2 tanker and Suezmax class tanker is analyzed, and it was shown that the Minorsky's formula, which assumes same collapse length for striking and struck ship, gives incorrect estimation of the energy balance when the strength of ship bow and side has big difference. Also, the results are compared with those by dynamic FEM analysis, and good agreements are observed. It was shown that the simplified analysis method is an effective tool in the early design stage.
