“…During the solution process, the optimization results of the previous stage are continuously used to carry out the optimization solution of the next stage. The ballast water allocation problem of rescue robots is regarded as a continuous problem, and a dynamic programming algorithm is used to solve the optimal decision 22 – 26 . The conceptual diagram of the dynamic programming algorithm is shown in Fig.…”

To improve the space attitude adjustment efficiency of the robot designed in this study, the average water level height variation of each ballast tank during the rescue process and the ballast water filling mass before the rescue process are taken as optimization variables, the minimal ballasting time during rescue process as the optimisation objective, and the heel and trim inclination angle, and stability in the rescue process as the constraint conditions. For the first time, an optimization method of a rescue robot space attitude adjustment scheme based on a dynamic programming algorithm is proposed. Relevant experiments and data collection were carried out with a model robot with a physical ratio of 1:2. MATLAB simulation and model robot experimental results show that compared with an empirical scheme, the total deployment time and ballast water total allocation mass are reduced by 11.07% and 30.79%, respectively, and the heel and trim angle variation stability is increased by 4.18% and 8.67%, respectively. The optimization model and algorithm are beneficial to improve the space attitude adjustment efficiency and stability of the rescue robot in this paper, and it is also easier to transfer to other fields of ballast water allocation, which has strong practical engineering significance.

Utilizing the AIS data and global ocean wave data, the vertical bending moment (VBM) that acted on the actual ships was clarified. The long-term prediction was performed based on the short-term analysis of VBM on actual ships in the worldwide sea area. The effect of storm avoidance operations on wave height is about 22% in worldwide sea area. The effect on VBM in the worldwide sea is about 16%. These effects are greater than that in North Atlantic.
