Integrated structure system of ultra-large floating platform and wave energy device based on hybrid mooring

Abstract

The invention discloses a superlarge floating platform and wave energy device integrated structure system based on hybrid mooring, and belongs to the field of marine energy resource utilization. The integrated structure system comprises a superlarge floating platform, an anchor chain system, a tension leg system and an oscillating floater type wave energy power generating device. The oscillating floater type wave energy power generating device converts the swinging of a floater into the horizontal movement of a piston rod in a gear and rack transmission mode and drives a motor of a bidirectional hydraulic power generation system to generate power. The wave energy device outside the superlarge floating platform can provide considerable energy supply for the superlarge floating platform through incident wave energy and can also effectively weaken the incident wave loads acting on the superlarge floating platform and reduce the movement response of the platform; by means of a tension legand anchor chain hybrid mooring system, the movement performance of the superlarge floating platform can be improved, that is to say, the torsion movement of the platform is restrained by the tensionleg system, the horizontal movement of the platform is restrained by the anchor chain system, and the safety and stability of the superlarge floating platform are improved.

Description

technical field [0001] The invention belongs to the field of ocean energy utilization and relates to a super large floating structure, in particular to a super large floating platform combined with a wave energy generating device. Background technique [0002] The vast sea, which covers more than 2 / 3 of the total area of ​​the earth, contains extremely rich undeveloped resources, while the development of land resources will inevitably reach its limit in the future, and the development of sea resources will inevitably become the main strategy for economic development of all countries. Faced with this situation, countries have begun to invest in research on very large floating structures (VLFS). VLFS is a new type of marine structure. Compared with ordinary offshore platforms, it has the characteristics of wide area, easy multi-functionality, and strong comprehensiveness. It can be used not only for the development of sea resources, but also for expanding the land area of ​​co...

AI Technical Summary

Problems solved by technology

[0004] The shortcomings of the existing technology are: VLFS has a strong dependence on wave walls or natural barriers such as islands, and has poor resistance to deep-sea loads without barriers. Research on wave-suppression strategies is still very limited

At present, there is still a lack of VLFS that can combine the use of wave energy generation devices for energy supply and weaken wave force loads.
