Abstract
This paper presents a method for the design modification of a damaged free-fall lifeboat (FFLB) through the results of a skid-launching free-fall test in the following phases: sliding, rotation, free-fall, and water entry. In the water entry phase, the damage to the FFLB is remedied structurally by reducing the top deck impact area and impact pressure and by increasing the modular factor of the roof deck in order to modify the structure of the deck and its shape. Thus, it can be seen that the proposed method can be applied to improve the existing design of the FFLB.
