Numerical estimation of ultimate strength on double hull oil tanker cargo area

Abstract

Ship’s hull consists of many elements located in deck, side shell and bottom structures. Those elements are unstiffened and stiffened plates and resist all the internal and external loads like cargos and waves. The primary element support the longitudinal strength is always to be investigated under loading conditions. The loads act perpendicular along the hull is resisted from these elements. The objective of the present study is to estimate the ultimate strength of Double Hull Oil Tanker cargo area using numerical analysis. Two Double Hull Oil Tankers are taken as the object in this study. The cargo tank is considered to be analyzed and the shell element is used to the entire model. The bending moment is connected to Multi-Point Constraint (MPC) at one side and the other side is constrained. The ultimate strength of chosen oil tanker is conducted under hogging and sagging conditions.
