This paper provides a new contribution to the simplified analyticaltreatment of collisions between two ships. It is directly connectedto the well-known super-elements method, which is a simplifiedprocedure allowing for a quick estimation of the damages causedto both the striking and struck vessels during such events. In thisarticle, a new analytical formulation is presented for estimatingthe impact resistance provided by inclined ship side panels. Twodifferent scenarios are treated. We first deal with the case of animpact between the oblique plate and the stem of the striking ship,and then we consider the situation where the inclined panel isimpacted by the bulb. For these two scenarios, an analyticalformulation relating the force and the penetration is provided andthese developments are validated by comparing them to the resultsof finite elements simulations. Finally, the new inclined platesuper-element is integrated in a simplified model of a frigatecollided by another ship, and the resistance given by the superelementsmethod is then compared to the one obtained by a numericalsimulation of this collision.
