By simulating the hydraulic parameters of the return pipeline under different water depths, inner diameters of the return pipeline, and drilling fluid densities, the required pump pressure and pump power data of the subsea pump under different conditions are obtained, which serve as the basis for optimizing the parameters of the subsea pump and the size of the return pipeline.
