Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ocean engineering equipment, in particular to a combined floating flexible wave-damping system and an operating method. BACKGROUND

[0002] In recent years, with the need of human beings for offshore islands and resource development and utilization, offshore floating bridges, floating piers, fishery breeding and offshore operation platforms are increasingly applied, and the demand for coping with adverse sea conditions is increasing.

[0003] As an important hydraulic structure, the wave-damping system is mainly used for defending the waves from the open sea, maintaining the stability of the internal water area of the pier and the port, providing a safe water area environment for the ship to enter and exit the port area, loading and unloading operations and personnel boarding and alighting, and protecting other engineering structures in the port. At the same time, the wave-damping system can also protect the coastline from erosion.

[0004] The fixed wave-damping system can effectively reduce waves and maintain the stability of the water surface of the port area. However, with the development of floating piers and the deepwater and offshore development of ocean engineering, the construction of the fixed wave-damping system is more complex and the engineering cost increases dramatically, which is basically impossible to implement in deep-sea conditions. Moreover, the circulation of water in the sheltered area is limited, which can easily cause sediment deposition and destroy the balance of the ecological environment in the sheltered area.

[0005] In the ocean, the energy of waves in water movement is basically concentrated in the surface water. In the water depth of 2 to 3 times the wave height below the water surface, 90% to 98% of the wave energy is concentrated. The traditional fixed wave-damping system uses more materials in the lower part of the water body with less energy, and uses less material in the upper part of the water body with more energy. The use of materials is not suitable for the distribution of wave energy. Therefore, the development of a floating wave-damping system that can be used is an important measure that ocean development and utilization must face. SUMMARY

[0006] In view of the above-mentioned shortcomings in the prior art, the present application provides a combined floating flexible wave-damping system and an operating method, which can realize efficient wave attenuation, convenient installation in all sea areas, small impact on the ecological environment, and repeated assembly.
