“…Zhang et al [8] addressed the experimental and finite-element simulation studies on scaled double¬ hull side structures quasi-statically punched at the mid-span by conical and knife edge indenters to examine their fracture behaviors and energy dissipation mechanisms. The ultimate strength of double hull oil tanker due to grounding and collision was conducted by Latumahina and Muis Alie [9], the collision damaged was modeled by removing the element at the side shell of the ship. The ultimate hull girder strength was analyzed by Muis Alie and Latumahina [10] by considering longitudinal stiffeners.…”

The hatch opening has function to enter the load into the cargo hold. One of the ship type like this is Bulk Carrier. The hatch opening must be designed in suitable way because its influence to the ultimate strength since the hull girder under longitudinal bending moment. The application of the hatch opening on the ship’s deck should be considered for the ship design critreria. The objective of the present study is to analyze the ultimate strength with and without hatch opening subjected to longitudinal bending moment. The cross section of box girder is used to analyze the effect of hatch opening to the ultimate strength. This cross section of box girder is adopted for simple calculation. The application of Multiple Point Constrained (MPC) is adopted to analyze the box girder under longitudinal bending moment. The cross section of box girder is assumed remained plane during progressive collapse. The material such as density, yield strength, elastic modulus and poisson ratio are homogeneous. The type and dimensions of the stiffeners are also identic. The only one of the difference for the stiffener is number due to the hatch opening at the top of the box girder. It is found that the ultimate strength of the box girder with hatch opening is smaller than without opening one.
