Abstract

A floating protection system is presented to protect bridge structures from vessel impacts. Based on general contact impact nonlinear finite element technique, the high resolution models of the 5,000-DWT ship and the protection system are developed to evaluate the performance of the floating protection system under vessel collisions. The results show that the protection system can effectively absorb the moderate impact energy from the ship and avoid the damage of both the ship and structures. Finally, a general design procedure is discussed briefly for practical design.
