Overall Shape Optimization of Offshore Oil Removal Tanker Based on Fluent

Abstract

In recent years, marine oil spill accidents have occurred frequently. A large number of scholars at home and abroad have conducted in-depth theoretical and experimental research on offshore oil removal tankers. However, the research on its full-scale driving stability and drag reduction performance was still insufficient. The overall efficiency of the oil removal tanker was low, and its resource utilization rate was not high. In this paper, an optimization method based on the whole modelling of the oil removal tanker was proposed. The CFD computational fluid dynamics method was adopted, which has been verified by validity. By studying the optimization plan of the overall shape, the overall work efficiency and the drag reduction performance of the oil removal tanker could be improved, and the energy could be saved. The final drag reduction was reached up to 515.86kN, a decrease of about 21.76%, and the drag coefficient was reduced by 0.479. This paper provided an important reference for the research and development of the offshore oil removal tanker by the optimization method of the oil removal tanker and the overall shape optimization scheme of the oil removal tanker on the sea.
