Ultra-Large Floating Platforms Based on Modular and Hybrid Moorings

Abstract

The invention discloses a superlarge floating platform based on modularizing and hybrid mooring, and belongs to the field of marine energy resource utilization. The superlarge floating platform comprises a central large platform module, a small platform module, a tension leg system, an anchor chain system, an oscillating floater type wave energy power generating device and module connecting components. 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 amotor of a bidirectional hydraulic power generation system to generate power. The module connecting components are divided into two modes according to the sizes of the connected platform modules, power generation is realized through the relative torsion and horizontal bidirectional movement between small platforms and large platforms and the relative torsion between the small platforms, and the relative movement between the modules is relieved when energy supply is obtained. The wave energy device outside the superlarge floating platform can provide energy supply through incident wave energyand can also effectively weaken the incident wave loads and reduce the movement response of the platform; by means of a hybrid mooring system with the tension leg system and the anchor chain system, the safety and stability of the whole platform can be ensured.

Description

technical field [0001] The invention belongs to the field of ocean energy utilization, and relates to a large ocean floating structure, in particular to an ultra-large floating platform based on modular and mixed mooring. Background technique [0002] Due to the gradual saturation of the development of land resources, countries began to turn their attention to the ocean, which contains a variety of rich resources waiting to be developed. In order to promote the exploitation and utilization of marine resources, researchers proposed a very large floating structure (VLFS) VLFS is a special ocean platform structure, which has the characteristics of wide area, easy multi-function, and strong comprehensive performance. It can not only be used as a platform for marine resource development, but also as an urban expansion platform. construction, naval bases, etc. However, due to the huge size of the VLFS and the huge ocean load, it must be modularized, spliced ​​by several basically...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of existing technologies are: VLFS is relatively dependent on wave walls or natural barriers such as islands, and has poor resistance to deep sea loads without barriers

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