In order to design steel offshore structures against impact loads due to accidental collisions by ships, it is necessary to evaluate the plastic energy absorption capability of the structure's members. In this paper, the local energy absorbed at the point of impact and in its immediate vicinity is first considered. Then the overall energy absorption capability of a tubular member is studied when it deforms in bending. A simple method for estimating the extent of damage from collision with a typical supply vessel is suggested, and a specific application is discussed.
