The horizontal thrusters located as X shape is a commonly used configuration in remotely operated underwater vehicle (ROV). To improve the motion performance of the remotely operated underwater vehicle with this configuration for some typical operation tasks, a multistep thrust allocation method based on priority idea is proposed. Firstly, the thrust allocation result of every single force/moment among the horizontal thrusters is obtained by using a piecewise calculation method. Then, a thrust allocation function of multiple forces and moment is constructed, transforming the thrust allocation problem into a multiparameter optimization problem. The objective function of the optimization problem is established based on priority idea, and limits of the thrusters are considered as constraints. Finally, a thrust redistribution method is adopted in order to further utilize the unsaturated thrusters in the propulsion system. Simulation results show that the proposed thrust allocation method has various advantages over the pseudo-inverse method, which makes the remotely operated underwater vehicle perform perfectly in the given operation task. The proposed method has important practical value and application prospects.

“…As in [15], [47], [58], [59], conflicting objectives of reducing GHG emission and overall operational cost are considered. Some additional objectives which are included in the cost function are optimizing ESS size, minimization of fuel consumption [39], [45], [46], and minimization of the overall mechanical losses [96]. In addition, to enhance the performance of the local optimization of NSGA-II in the population diversity preservation, an improved NSGA-II algorithm was adopted in [39] by replacing the polynomial variation with difference mutation operators.…”

Despite the advantages of employing an electric propulsion system in All-Electric Ships (AES), additional power fluctuation sources have emerged in the ship power system as a result. Since the propellers are the primary power consumers in the AES, these fluctuations may significantly affect its power system power quality. Thus, for optimal performance of the ship power system, these fluctuations need to be rigorously investigated at the design level of vessels. Waves collision is one of the critical conditions where propellers inject power fluctuations into the ship power system. Therefore, a comprehensive model is essential to analyze the propellers inand-out-of-water effect on the ship power system thoroughly at the design level. This paper proposes a model-based approach for determining propeller immersion depth variations in collisions with different wave classes. According to this approach, the propellers thrust loss factor caused by the in-andout-of-water effect can be identified. The proposed method is then applied in an integrated AES model. This model interconnects the ship motion and power system dynamics. The in-and-out-of-water impact on the ship power system can be explored precisely in the model-based design of the vessels by utilizing the proposed model. In the end, the proposed method and the interconnected model have been used to simulate a notional ship in a wave collision condition. Simulations demonstrate that the proposed approach can accurately map the substantial impacts of the vessel-wave encountering conditions on the frequency, voltage, and generally on the power quality of the AES power system.
