Abstract
<p>Ship collision analyses for the hard impact on rigid wall and the soft impact on protective structure were carried out to evaluate the ship collision force on substructure and the energy dissipation of pile-supported structure during ship collision. The ship with bulbous bow and the pile-supported structure were modeled in a finite element analysis package. As results, the deformations, displacements and stresses of protection system were obtained and the kinetic energy of colliding ship were analyzed into the absorbed parts such as plastic deformations of protective structure and vessel, friction between structure and vessel, rebounding of vessel, etc. The collision energy of vessel was almost translated to the plastic deformation energy of the pile-supported structure and the considerable energy was also translated to that of vessel.</p>
