Marine economic development basic platform module

Abstract

The invention discloses a marine economic development foundation platform module. The marine economic development foundation platform module comprises a main floating body frame formed by cylindricalfloating bodies which extend in the annular direction and are connected end to end to form a closed annular shape, and an operation platform which is arranged above the main floating body frame and provided with an offshore operation platform layer, wherein the operation platform is connected with the main floating body frame through a first connecting column extending vertically, and the offshoreoperation platform layer is connected with a superstructure used for conducting various offshore operations; the module further comprises a lower frame body which is arranged below the main floatingbody frame, is of a closed annular structure and is connected with the main floating body frame through a second connecting column extending vertically; and the displacement of the main floating bodyframe is greater than the total structural weight of the marine economic development foundation platform module. The foundation platform module has large reserve buoyancy and a large waterline plane,the overall stability, the storm resistance and the adjusting capacity adapting to severe sea conditions are improved, and better safety is achieved; and the structure is simple, the overall framing performance is high, and the strength of the overall frame is improved.

Description

technical field [0001] The invention relates to the technical field of marine economic development, and more specifically, to a basic platform module for marine economic development. Background technique [0002] More than 2 / 3 of the world's oceans contain very rich tourism, biological, oil and mineral resources. The economic development of the ocean by building an operating platform on the sea has extremely far-reaching strategic significance for the development of our country's marine resources, the rational and effective use of sea space, and the sustainable development of the economy. At present, offshore operating platforms mainly include ships, fixed artificial islands, and offshore platforms (a truss structure that is above the sea surface and has a horizontal platform surface), etc. Ships are mainly used to transport goods. The construction of artificial islands requires a large investment, takes a long time and cannot be moved. Due to the harsh sea environment, the...

Problems solved by technology

Due to structural constraints, the second floating body 300 of the floating platform in the prior art is located below the water surface, and the first floating body 200 is wholly or partially located below the water surface, and the second floating body 300 and the first floating body 200 are all dispersed, resulting in the structure The reserve buoyancy of the floating platform is small, and when encountering severe sea conditions, it cannot adjust its draft level to adapt to the sea conditions, and its ability to resist storms and environmental adaptability is poor; and the passage between the first floating body 200 and the second floating body 300 is very complicated. The connection of the connecting column causes too many connection nodes, the overall strength is low, and it is difficult to improve the fatigue strength and stress control
