[0012] like Figure 1 and Figure 2 As shown, the FPSO ultra-high flare tower hoisting support frame includes a main support pipe 1, an oblique support pipe 2, a lifting point support 3, a lifting point support sealing plate 4 and a main support pipe connecting flange (5), the oblique support pipe 2 is fixedly connected between the main support pipes 1, the lifting point support 3 is fixedly connected to the main support pipe 1, the lifting point support sealing plate 4 is installed on the lifting point support 3, and the main support pipe connecting flange 5 is installed at the bottom of the main support pipe 1. The main support pipe 1, the oblique support pipe 2, the lifting point support 3, the lifting point support sealing plate 4 and the main support pipe connecting flange 5 form a space truss structure, and the space truss structure is connected to the flare tower body through bolts. In the actual operation process, firstly, according to the crane working condition requirements, the flare tower lifting point position and the lifting point spacing are determined, so as to determine the overall size and installation position of the entire support frame, and the overall prefabrication of the two support frames is completed in the workshop respectively, and the support frames are bolted to the flare tower body through flanges. According to the designed lifting procedure, the hook is hooked, turned over, unhooked, and the lifting frame is dismantled.
