Ship Collision analysis of tanker using finite element method at high and low impact velocities

Abstract

The aim of this paper presents a study of ships collision to improve crashworthiness of double side tanker ships and minimize accidental oil spills in the event of collision. Structural design of ships against collision requires prediction of the extent of damage to ship structures subjected to impact. Ship design against conventional loads such as shearing, bending and local buckling and the accidental loads requires applying different stiffening systems for ship structures to sustain. Tankers accidents may cause serious environmental pollution, so it has to be assessed against collision damage in ship structural design. To predict accurately the extent of collision damage, FE modeling of mid-ship region of the double side tanker using ABAQUS software is applied. In order to study the effect of ship collision at 12 knot on oil tanker strength when using additional cross-tie members in the double side, a comparison is made between the original design of the mid-ship region and the suggested stiffening system with cross-tie members with reference to absorbing energy, miss stress and acting forces against the penetration depth. Keywords: ship collision; FEM; structural crashworthiness; cross-tie; stiffened panel
