Background
The SALM (single anchor leg mooring) system itself is a form of mooring system that is relatively simple and compact in construction. The tension leg type anchor chain is connected with a buoy or a hinged column type rigid vertical pipe directly replaces the anchor chain (shallow water form), and in a sea area with larger water depth, a combination form of combining an underwater rigid vertical pipe and the tension leg type anchor chain or a combination rigid vertical pipe (deep water form) can be adopted. The moored ship is connected with the anchor chain-buoy system through a flexible mooring cable or a rigid arm. Like an inverted pendulum, the restoring force of such single point mooring systems is mainly provided by the buoyancy of the buoy or the buoyancy restoring moment of the column riser. The moored ship drives the buoy to move laterally under the weathercock effect, so that the buoyancy of the buoy is changed, and nonlinear mooring force is generated. The ship can only resist the environmental force with medium and low intensity, and the swing amplitude of the bow is larger under the severe environment, which is not beneficial to mooring.
The existing single anchor leg buoy single point mooring system device moors through the connection of a mooring bow cable of a ship and a single point buoy, the moored ship drives the buoy to move laterally under the weather vane effect, the bow connected with the bow cable can generate the situation of large-amplitude bow shaking motion under the condition of complicated and severe sea conditions, and the safety is reduced, so that the existing mooring system has limitation and instability.
