Abstract: Currently, floating facilities combing high-precision positioning capabilities with the characteristic of requiring no external driving force remain a technical challenge in mountainous rivers. To address this, a novel inland water floating facility equipped with a self-driven mutually coupled tension mooring system was proposed. Through theoretical research, mechanical analysis was conducted on the overall floating facility and the self-driven mutually coupled mechanism, and the theoretical formula for positioning accuracy was derived. Combined with physical experiments, the effects of flow velocity and water level on positioning performance were investigated. The research results show that under different flow velocities, the maximum planar offset of the floating facility is 0.32 m. The self-driven mutually coupled mechanism dynamically adjusts the cable forces at the bow and stern, with the bow cable force being greater than that at the stern, and the total cable force remains stable at around 2 250 kN on average. Under different water levels, the maximum planar offset is 0.2 m. The proposed novel floating facility possesses self-restraint high-precision positioning capability and adaptive adjustment characteristics of tensioning cable tension without external driving force.
