This work aims to compare deflection in the vertical direction between the perfect T- and RSF-stiffeners, which subjected by forces and pressures. The geometry of stiffener models have studied the conventional T-stiffeners model design as the actual double hull oil tanker and the RSF-stiffeners are new type design based on T-stiffener specifications. The deflection theories of simply supported beam were studied by double integral method and moment area method. Finite Element Analysis (FEA) is used to design and simulation the deflection in vertical direction and maximum equivalent stress of stiffeners after subjected force and pressure within the same boundary condition. All stiffener models are obtained and result from FEA are shown in linear and nonlinear curves. The verification between theoretical and FEA results are in agreement. The load-deflection curves are shown that the performance of all RSF-stiffeners are greater than the conventional T-stiffener.
