Objective

In order to improve the safety of ship navigation, this study focuses on virtually aided ship navigation strategies.

Methods

Two different inland river routes are chosen for the simulation of virtually aided ship navigation models based on the fluid-structure interaction mechanism, while taking the navigation rules and flow details of the rivers into consideration. The simulation of the ship sailing process on a typical inland river route under specific current conditions provides the corresponding virtually aided navigation plan in which the ship's velocity, location and course are obtained in a timely manner.

Results

It is found that the simulation method established on the basis of Fluent can be used to solve the problems of multi-degree-of-freedom motion and fluid-structure interaction. When sailing through bends or branches, steering with a small rudder angle over long distances ensures safe navigation and prevents speed reduction and significant lateral displacement.

Conclusion

The proposed method can be effectively combined with the flow field information of digital channels to simulate the ship sailing process, thereby providing data support for the decision-making of intelligent navigation on inland river routes.

The ship platoon will become an important form of water transport in the future. This paper analyzes the characteristics and control principle of ship platoon cooperative control, and analyzes the current situation and methods in the four aspects of ship-shore cooperative platoon, platoon control model, platoon motion control and typical platoon applications. The current bottlenecks of ship platoon control technology are summarized, including human-machine fusion control, platoon motion control uncertainty modeling, platoon cooperative consistency control modeling, robust control under communication constraints and consistency control. In the future development of ship platoons, we should focus on solving the problems of platoon motion modeling based on data-driven and mechanism fusion, ship platoon control based on the biological group mechanism and the application of hierarchical control in ship platoon control.
