“…Techniques used for creating and modifying hull forms can be classified into two major categories: fully-parametric models defined by Harries 1 and applied by researchers 6–9 or relying on one or more control polygon methodologies such as NURBS, B-Surface, and subdivision surfaces. 10–12 Fully parametric modelling techniques are generally more complex to construct, but more fast and robust with respect to geometric variations, allowing both global and local form changes.…”

This study presents a simulation-based optimization procedure of a high-speed vessel. The presented procedure is applied on benchmark form Model 5365, a 1/8.25 scale model of the transom-stern, high-speed research vessel, R/V Athena. The procedure integrates parametric model generation, viscous numeric resistance analysis, and genetic algorithm evaluation. CAESES, a unique simulation-based design platform, is used to collect the process under one roof and handle the process automatically. The fully-parametric form is constructed by means of main characteristic curves, control curves, and various parameters to achieve quick-variation of hull forms. The numeric resistance analysis are performed via viscous flow solver and the calm-water total resistance force is defined as the optimization objective. The NSGA-II algorithm is used for evaluation of analysis results and regeneration of form variants, to achieve total resistance minimization. The optimization results show that the optimized hull form has lower resistance than Model 5365 form; a form variant with 2.02% total resistance reduction was obtained.

“…Shape optimization refers to the optimization of domain boundaries and plays an important role in structural design. For instance, shape optimization plays a crucial role in the design of airfoils (He et al 2019;Wang et al 2018;Schmidt et al 2013) and boat hulls (Lombardi et al 2012;Marinić-Kragić et al 2016;Abramowski and Sugalski 2017). Shape optimization is also a useful refinement step to be employed after topology optimization (Bendsoe and Sigmund 2004, Ch.…”

“…Most of the above research is to improve the hull structure of the oil removal tanker and improve its local working performance through experimental verification, which has certain limitations [11]. Due to the complexity of hull processing technology, there is little research on the overall modelling and drag reduction performance of oil removal tankers [12]. At the same time, under the background of the rapid development of CFD technology, aiming at the deficiency of existing research, this paper puts forward a systematic and general optimization method based on the whole modelling of oil remover.…”

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.
