ON DESIGN OF DOUBLE HULL TANKERS AGAINST COLLISION

This paper describes a design procedure for the side structure of double hull tankers in ship-ship collisions. The procedure is separated into two parts: analysis of the external mechanics and analysis of the internal mechanics. The former provides the loss of kinetic energy during the collision and the latter gives the collision force-indentation response of the colliding ships. An optimum design of the double side structure is determined by considering work dissipated by structural failures until rupture of the inner hull equal to the loss of kinetic energy during the collision. As an illustrated example, the procedure is applied to a double hull VLCC in collision with the bow of a container ship of 40,000dwt. The design curve for determining an optimum width of a double side in the collision of double hull tankers is proposed. The design curve proposed by Germanischer Lloyd is compared.
