Collision with a Crushable Bow
Abstract:Oil tanker collisions and groundings pose the potential for large spills. Currently, the International Maritime Organization and national governments have design standards for tankers that do not account for a vessel's crashworthiness. By using crashworthiness, a vessel can be optimally designed for both weather and extreme loading situations. Minorsky  examined the problem of collision damage on a vessel side wall. Using previous collision data, Minorsky generated a simple damage volume to kinetic energy relationship for the safety of reactors on nuclear-powered ships. Since then, many researchers have provided solutions for the extent of damage on a tanker based on an assumption of a rigid bow collision. Such a formulation does not account for the energy consumed by the bow deformation. As a result, the damage extent to the side of a vessel is overestimated. By adding a crushable bow, the final result will allow for a more optimally designed vessel. This paper provides a simple closed-form solution for modeling the collision resistance of the bulbous bow portions of tankers. This closed-form solution can be combined with side collision solutions to optimally design a tanker for extreme loading conditions.
