The purpose of this paper is to present analytical, closed-form
expressions for the energy released for crushing and the impact
impulse during ship collisions. Ship-ship collisions, ship
collisions with rigid walls and ship collisions with flexible
offshore structures are considered. The derived mathematical
models include friction at the contact point so that situation
where the collision results in a sliding motion is included.
Results obtained by application of the present procedure are
compared with results obtained by time simulations and good
agreement has been achieved. In addition, a number of illustrative
examples are presented. The procedure presented in the paper is
well suited for inclusion in a probabilistic calculation model for
damage of ship structures due to collisions.
