A self-resetting elastic sleeve type single point mooring system

Abstract

The invention discloses an automatic reset elastic sleeve type single point mooring system, and relates to the technical field of single point mooring. According to the automatic reset elastic sleeve type single point mooring system, an ocean nuclear power platform is moored on an ocean surface, so that the movement range of the platform is reduced, the operation reliability and the stability of the ocean nuclear power platform are improved. The automatic reset elastic sleeve type single point mooring system comprises a guide tube rack, a truss main shaft, mooring bearings, swinging rotation bearings, two elastic sleeve type mooring legs, two transverse beams, universal couplings and ship bow brackets, wherein the guide tube rack is fixed on a pile base at the seabed; the truss main shaft is arranged at the top end of the guide tube rack; the mooring bearings are mounted on the truss main shaft; the swinging rotation bearings are connected on one side of the mooring bearings; the two elastic sleeve type mooring legs and the two transverse beams form one trapezoid rack; the tops of the elastic sleeve type mooring legs are connected with the swinging rotation bearings; the bottoms of the elastic sleeve type mooring legs are connected with the ship bow brackets through the universal couplings.

Description

technical field [0001] The invention relates to the technical field of single point mooring, in particular to an automatic reset elastic sleeve type single point mooring system. Background technique [0002] Marine nuclear power platforms are long-term moored in the ocean. They are ship-borne floating nuclear power plants that can provide resources such as electricity, heat, and fresh water for offshore oil drilling platforms, offshore islands, and other offshore facilities. The marine nuclear power platform is far away from the coast and is in an island operation state. Therefore, to ensure the stable and safe operation of the reactor of the marine nuclear power platform, it is necessary to realize the reliable mooring of the platform. [0003] The single point mooring system has a good "weather vane effect". After mooring, the hull can rotate 360°, which keeps the mooring load of the ship at a minimum and improves the reliability and safety of mooring. At present, the "FP...

Problems solved by technology

However, all the above SPM systems have their own defects, such as catenary buoy SPM relative motion is too large, poor positioning ability; soft rigid arm SPM has poor elasticity and poor resilience adaptability; turret Type single point mooring has a long construction period and has high requirements on the hull structure

[0004] The "KLT-40S" floating nuclear power plant under construction in Russia uses a ship-type platform, and its mooring points are close to islands or ports. Stability, safety, and obvious effect; but there are great limitations, not only high cost, but also a large amount of engineering, not suitable for drilling platforms and islands far away from the coastline, and not easy to promote and apply
