Abstract

The invention discloses a floating supporter for blocks of an ocean platform, which comprises two oppositely arranged continuous box beam piston shoes and a plurality of bottom transverse continuous box beams arranged between and fixedly connected with the two continuous box beam piston shoes. Two oppositely arranged top vertical continuous box beams are arranged in inclined upper direction of the continuous box beam piston shoes and a plurality of top transverse continuous box beams fixedly connected with the top vertical continuous box beams are arranged between the two top vertical continuous box beams. A plurality of support columns are arranged between the top vertical continuous box beams and the continuous box beam piston shoes. The support columns are fixedly connected with the top vertical continuous box beams and the continuous box beam piston shoes respectively. The top vertical continuous box beams are provided with connecting members matched with the blocks to be installed, corresponding to the support columns.

Description

technical field [0001] The invention relates to a buoyant support device for an ocean platform block, which belongs to the field of ocean engineering installation. Background technique [0002] With the large-scale development of my country's offshore oilfields, offshore platform modules are showing a trend of large-scale and heavy-duty development. Large-scale platforms have multiple functions such as oil extraction and oil and gas processing, which is more conducive to reducing platform investment than building multiple small platforms with the same functions. For example, the largest block LD27-2PSP built in China weighs 10,600 tons, and the planned LW3-1CEP weighs 27,000 tons. For blocks of this size, the traditional hoisting installation method is no longer applicable, and it is inevitable to use platform block float-over installation. [0003] To realize the float-over installation of the module, a supporting device is needed to connect the module and the barge, and ...
