Ultimate strength analysis of stiffened plate variation on the longitudinal bulkhead of Double Hull Oil Tanker

Abstract

Loongitudinal bulkhead also gives significant effect to the longitudinal strength of double hull oil tanker. The stiffened plate attached at the longitudinal bulkhead must have enough strength to wishtand the liquid oil which has an impact to the longitudinal bulkhead correspond to longitudinal strength. The objective of the present study is to analyze the ultimate strength of stiffened plate on the longitudinal bulkhead of double hull tanker. The small section of stiffened plate with attached plating at the longitudinal bulkhead is considered to the analyzed. The numerical analysis is adopted to analyze the model. The stiffened plate is variated with the distance in terms of model breadth. The boundary condition is applied to the model including axial compression load. The behavior of the model is represented by stress and deformation. For the simple analysis, the welding residual stress, crack, and initial imperfection are not taken. The result obtains by the numerical analysis is presented together with the behavior in term of stress and deformation.
