Abstract

In this work, the replacement of nickel and composite materials instead of metal vessels in the oil industry has been investigated. The modeling is based on finite elements, and the capabilities of Abaqus finite element software have been used to consider the vessel's behavior against lateral forces and hydrostatic forces. In this regard, considering the high resistance of this material, the stresses and displacements experienced by the vessel against various forces have been investigated. Also, the behavioral comparison between the vessel made of nickel and composite and the metal vessel in this research is of interest. The results show that this type of vessel has a high resistance to lateral forces and a high potential to resist various mechanical forces. Static stresses in vessel optimization have been reduced by using nickel material and 400 Psi composite. Also, it has been reduced by 750 psi and 1.5 in against the stresses of the lateral forces of the wind and the displacement of the vessel against the force of the earthquake. Finally, displacement against wind force is optimized by 3 in, which shows the proper performance of the vessel.
