Semi-submersible module and its assembly method for combining large-scale floating body on water

Abstract

The invention provides a semi-submersible module for combining into a large-scale floating body on the water and an assembling method thereof, and belongs to the field of large-scale combination floating body structures and assembling. The semi-submersible module comprises a floating box, a vertical column, an upper platform, a floating box connection bridge, and an upper platform connection bridge, wherein the floating box is fixedly connected with the upper platform through the vertical column to form the semi-submersible module, and standard liquid cabins inside the floating box are gathered into a ballast centralized control room of the upper platform through a remote control pipeline and a remote control valve member of the vertical column. The semi-submersible module is simple in structure and easy to build, and capable of being assembled into a large-scale combination floating body on the sea. Semi-submersible modules are connected through connection bridges in a welded mode, and works of welding, coating, assembling and the like are constructed on the water. The welded connection through the connection bridges keeps structure continuity among the modules, and good structure strength is achieved. The connection bridge members are cantilever beam resembling structures, have certain flexibility and have certain error tolerance performance for building errors and method deformation errors, so that module building is facilitated and smooth assembling and welding work on the water are guaranteed.

Description

technical field [0001] The invention relates to a semi-submersible module for combining large-scale floating bodies on water and an assembly method thereof, belonging to the field of large-scale combined floating-body structures and assemblies. Background technique [0002] Large-scale combined floating bodies include offshore airports, offshore docks, offshore operating platforms, large pontoon bridges and floating cities, etc. They are effective equipment for developing and utilizing marine resources and defending national territorial waters. In view of the important economic and strategic status of large-scale combined floating bodies, my country is currently conducting in-depth research on large-scale combined floating bodies. The semi-submersible structure is the most widely recognized large-scale composite floating structure due to its advantages such as small wave load. However, the external dimensions of the large composite floating body are an order of magnitude la...

AI Technical Summary

Problems solved by technology

However, the dimensions of large composite floating bodies are an order of magnitude larger than conventional ships and offshore platforms, so they cannot be constructed by the construction methods of conventional ships and marine structures
