Title: Key Technologies for Autonomous Navigation and Cooperative Control of Unmanned Surface Vehicles
Abstract: Autonomous navigation and cooperative control of unmanned surface vehicles are critical technologies that ensure the safe and efficient operation of unmanned maritime systems in complex environments. To enhance the safety of current maritime transportation, reduce labor costs, and facilitate future ocean exploration and management, autonomous navigation and cooperative control for intelligent ships are of great importance. This report will share the key technologies in autonomous navigation and cooperative control of unmanned surface vehicles, focusing on related aspects such as multi-sensor information fusion and situational awareness, autonomous collision avoidance decision-making, path planning, and cooperative control. Finally, the future architecture of integrated maritime transportation/monitoring system is given.

Title: Design and Research of Vector Propulsion System for Underwater Vehicles
Abstract: To optimize the structural performance of vector thrusters and their application in underwater vehicles, it was studied by numerical calculations and experimental techniques.Including: Investigate the hydrodynamic performance of the vector thruster and optimize its overall structure and performance, Computational Fluid Dynamics (CFD) was employed to discretize the governing equations within the control domain. Through numerical simulations, the viscous flow field and open-water performance of the vector thruster were analyzed. A viscous flow field model for the thruster was established, and the Moving Reference Frame (MRF) method was used to simulate the vector thruster at various yaw angles. Using the control variable method, different rotational speeds, yaw angles, propeller configurations, and wake effects were examined. Based on the results, the hydrodynamic coefficients of the thruster were determined. System experiments are designed to verify above researches.

Title: The Effective Application of Electronic Devices in Ship Engineering
Abstract: Exploring the ocean is an important direction for future development, and ships, offshore platforms and underwater equipment in ocean engineering cannot do without the support of electronic devices. This report takes the widely used marine steel in marine engineering as an example to explore quality control and monitoring in the manufacturing process of marine steel. During the continuous casting process of marine steel, the solidification of slab always deviates from ideal state, the non-uniform heat transfer, deformation and friction have been the major reason of slab defects, which becomes the key factor to improve slab quality. Rationally connect numeral simulation and measured data to investigate the asymmetric and non-uniform character during mold, and discuss the key factors which would affect the slab quality such as heat transfer/solidification, stress/deformation, friction/lubrication and gap distribution under real conditions, is one of the key point of the research. In view of this, this study collects production data in real time through electronic devices such as thermocouples, combines measured data with numerical simulation, and monitors and regulates the quality of the production process of marine steel.
