According to the review of the frequent mooring broken cable accidents around the world, this paper analyzes the current situation of port ship mooring operation, and analyzes the innovative research, development and application of mooring technology at home and abroad. In this paper, on the basis of the motion compensation principle of active anti-rolling, and relying on the parallel platform, an intelligent mooring system which can act as both cable and fender function is developed. The system can autonomously adapt to the ship’s six-degree-of-freedom movement, monitor the ship’s load data, and realize the active control of the ship through follow-up and damping, so as to achieve the purpose of autonomously controlling the ship-shore mooring process intellectualization.
