TANKER STRUCTURAL ANALYSIS FOR MINOR COLLISIONS
In a study of the behavior of a longitudinally framed oil tanker structure during a minor collision in which the cargo tank remains intact, a plastic analysis procedure, based partly on model tests and inspections of collision damage, was developed and applied to a limited number of idealized ship collisions. The mathematical model of the analysis procedure follows the various phases of structural behavior of the struck ship occurring as a collision progresses--bending and stiffener buckling of the stiffened hull plating followed by membrane stretching, web frame failures, etc., up to hull rupture. Both single- and double-skinned ships were studied. Parametric analyses using the analytical procedure have indicated that most (typically between 2/3 and 9/10) of the energy absorbed during a collision is that of membrane tension in the stiffened hull. Other significant energy absorbed is that of memebrane tension in the stiffened deck and in-plane shearing of web frames.
