Offshore floating island, offshore floating island group and construction method of offshore floating island

Abstract

The invention discloses an offshore floating island. The offshore floating island comprises a plurality of floating platform modules, offshore operation platforms, lower frame bodies and a mooring system, wherein all floating platform module are provided with main floating body frames formed by closed annular columnar floating bodies, the offshore operation platforms are arranged above the main floating body frames and are used for carrying various offshore operation buildings, the lower frame bodies formed by annular floating bodies below the main floating body frames, the offshore operationplatforms and the main floating body frames are connected with the lower frame bodies and the main floating body frames through longitudinally extending hollow connecting structures, and the hollow connecting structure is formed by floating bodies with hollow structures; the water discharge amount of the main floating body frames is larger than the total weight of the structures of floating platform modules, a mooring rope or an anchor chain connected with two adjacent floating platform modules, passage channels are arranged between floating platform modules and are used for carrying out personnel and cargo circulation, and the mooring system is used for fixing each floating platform module in a destination sea area. According to the offshore floating island, the offshore floating island group and a construction method of the offshore floating island, the offshore floating island has the advantages of being low in construction difficulty and cost, higher in storm resistance and capableof adapting to the self-adjusting capability of sea conditions.

Description

technical field [0001] The present invention relates to the technical field of offshore construction, and more specifically, relates to an offshore floating island, an offshore floating island group, and a method for constructing the offshore floating island. Background technique [0002] With the increase in population and the high-speed exploitation of land resources, we have gradually entered the era of economic development of the ocean, and the exploration of the ocean and various economic developments have become important research directions for human beings. At present, the artificial islands built in the sea are mainly divided into three categories. The first type is a fixed platform island, which requires a fixed connection between the operating platform and the seabed through a mechanism. The construction of such islands has great damage to the environment, poor applicability in the sea area of ​​the islands, and the difficulty of construction, high cost, and low ...

AI Technical Summary

Problems solved by technology

The construction of such islands has great damage to the environment, poor applicability in the sea area of ​​the islands, and the construction is difficult, costly, and low in return on investment, making it difficult to form mass-scale construction

The second type is based on islands and reefs. Although the island can be used for a long time, it requires complicated offshore construction, which causes great environmental damage, large investment, and long construction time.

The third type is an integrated floating island formed by a super-large integrated floating platform or directly connected by multiple small floating platforms through a connecting mechanism. The technology is difficult and the construction cost is high, and this type of integrated floating platform not only has a single structure model, but cannot be adjusted for various ocean development needs, but also does not have a large reserve buoyancy and the ability to adjust itself according to sea conditions. The ability of the storm needs to be improved
