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

Abstract

The invention discloses an offshore floating island which comprises a plurality of floating platform modules, and each floating platform module is provided with a main floating body frame formed by aclosed annular columnar floating body, an offshore operation platform which is arranged above the main floating body frame and is used for bearing various offshore operation buildings, and a lower frame body which is arranged below the main floating body frame and formed by annular floating bodies, wherein the offshore operation platform and the main floating body frame as well as the lower framebody and the main floating body frame are connected through hollowed-out connecting structures extending longitudinally, and each hollowed-out connecting structure is formed by a floating body of a hollow structure; the displacement of the main floating body frame is greater than the total structural weight of the floating platform modules; the offshore floating island further comprises mooring ropes or anchor chains which are used for connecting every two adjacent floating platform modules, passage channels which are arranged among the floating platform modules and are used for personnel andgoods circulating, and a mooring system which is used for fixing each floating platform module in a destination sea area. The offshore floating island is low in construction difficulty and cost, and has higher storm resistance and self-adjusting capacity adapting to 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
