Tower hoisting apparatus and method for assembling subsea tower foundation

Abstract

A tower hoisting apparatus including a plurality of vertical towers, a plurality of inclined support trusses, at least one load-bearing platform and a plurality of winch hoists. The plurality of vertical towers is spaced apart from each other and extends 5 respectively along a vertical direction. The plurality of inclined support trusses is respectively disposed adjacent ones of the vertical towers. The inclined support trusses extend obliquely from the adjacent ones of the vertical towers toward one another and converge between the adjacent ones of the vertical towers. The at least one load-bearing platform is fixed onto the inclined support trusses. The plurality of 10 winch hoists is installed on the at least one load-bearing platform. A method for assembling a subsea tower foundation uses the tower hoisting apparatus to connect an upper tower section to a lower tower section to assemble the subsea tower foundation. 12 20 25 20 50 35 02 J ul 2 02 5 A B S T R A C T 2 0 2 5 2 0 5 0 3 5 0 2 J u l 2 0 2 5 1 2 5 / 75 / 7 2c 1b 202 41a 201 2b ON FIG. 5 4a 3a 100 2a la 20 25 20 50 35 02 J ul 2 02 5 V O 2 0 2 5 2 0 5 0 3 5 0 2 J u l 2 0 2 5
