Title:
ASSEMBLED ALUMINUM PIPE, CONFINED CONCRETE AND STEEL PIPE COMBINED JACKET OFFSHORE PLATFORM AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/000604
Kind Code:
A1
Abstract:
The present invention relates to the technical field of structural works of civil engineering. Disclosed are an assembled aluminum pipe, confined concrete and steel pipe combined jacket offshore platform and a manufacturing method therefor. According to the technical solution, the assembled aluminum pipe, confined concrete and steel pipe combined jacket offshore platform consists of a jacket and a platform; the platform is mounted on the jacket; the jacket comprises guide pipes, horizontal platform braces, and inclined platform braces; the guide pipes are arranged in the vertical direction; a plurality of horizontal platform braces and inclined platform braces are provided between the guide pipes and inside the platform, respectively; the tops of the guide pipes are connected to the platform, and the bottoms of the guide pipes are fixedly connected to the seabed; the guide pipes comprise a plurality of guide pipe units connected to one another; the guide pipe units are aluminum pipe-confined concrete-steel pipe double-walled hollow components. The present invention effectively avoids the complex process of underwater welding and the potential safety hazards caused by insufficient welding strength. In addition, because the assembled structure is easy to disassemble, the recycling of the offshore platform becomes possible, and the assembly modularization of the offshore platform structure is achieved.
