Title:
PRE-STRESSED CONCRETE FLOATING PLATFORM FOR SUPPORTING OFFSHORE WIND TURBINE AND MARINE ENERGY GENERATOR
Document Type and Number:
WIPO Patent Application WO/2013/040871
Kind Code:
A1
Abstract:
A semi-submersible floating platform comprises at least three hollow cylinder concrete floating tubes (1). The floating tubes are connected through a transverse frame structure, to form a structure with a plane being a triangle, quadrangle, or a polygon. The floating platform is made of pre-stressed concrete and/or pre-stressed lightweight concrete and/or pre-stressed fiber concrete. On each platform, a horizontal axial wind turbine and/or at least one vertical axial wind turbine (41) is mounted, and optionally, a solar energy (49) and/or wave energy generator is mounted. Also disclosed is a construction and installation method of a pre-stressed concrete floating platform for supporting offshore wind turbine. Compared with the steel floating platform, the concrete floating platform has greatly reduced cost, a low structure gravity center, and higher structure stability. The platform construction and installation method is similar to the mature segmental precast pre-stressed concrete bridge segment assembly construction method. The platform is applied to offshore wind and electricity and ocean green energy source development in which the depth of water is 25 meters or 100 meters or even deeper.
