BOTTOM-MOUNTED OFFSHORE PLATFORM, OFFSHORE WIND POWER GENERATION DEVICE, AND OFFSHORE WIND CONDITION OBSERVATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/070786
Kind Code:
A1
Abstract:
Provided is a bottom-mounted offshore platform which, being bottom-mounted, can be installed offshore at low cost while enabling stable power generation and wind condition measurement. The bottom-mounted offshore platform is used to install a wind power generator 30 or a wind condition observation machine 35 on the ocean, and is provided with: a column part 1 having a lower end thereof arranged on an ocean floor 90, extending in a vertical direction with an upper end thereof protruding from the ocean, and having the wind power generator 30 or the wind condition observation machine 35 installed at the upper end; and a base part 2 that is installed on the ocean floor 90 and to which the lower end of the column part 1 is coupled. The column part 1 has a hollow floating part 4 and has at the lower end a weight part 3 that sinks the column part 1. The center F of buoyancy acting on the floating part 4 is located above the center G of gravity of the weight part 3 so as to hold the column part 1 in a vertical position. In addition, the lower end of the column part 1 is coupled to the base part 2 via a coupling structure 5 that allows oscillation of the column part 1.
