On the basis of the direct route method for design by analysis of the European Union standard of unfired pressure vessels design(EN13445-3),the gross plastic deformation design check(GPD-DC) of a subsea separator was studied.The numerical model of the subsea separator was built and verified by high-pressure expriments.The results show that the average relative error of simulation result is no more than 5%,which means the numerical model is accurate.The gross plastic deformation of subsea separator structure can pass the check.The subsea separator structure is safe enough.
