Problems solved by technology

[0003] If land cranes are used, it is difficult for ordinary wharfs to find existing lifting equipment suitable for flare tower hoisting. If temporary design and construction of lifting equipment suitable for flare tower hoisting is required, more investment will be added, and more importantly, the construction period will be affected. and other uncontrollable factors

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0026] Examples such as Figure 1 to Figure 4 Shown, the present invention discloses a kind of method that carries out FPSO flare tower hoisting with floating crane, and the concrete implementation of each step is as follows:

[0027] (1) Prefabricate the guide plate 8 on the support pipe 6 of the base of the flare tower to form a slideway;

[0028] like image 3 Or shown in 4, two guide plates 8 are installed on each support tube 6, and guide plate 8 is positioned at the inboard of support tube 6 on the flare tower base, and two guide plates 8 and support tube 6 encircle into slideway. When the legs of the flare tower 3 enter the slideway, they play a restrictive role in loweri...

Abstract

The invention discloses a method for hoisting an FPSO (floating production storage and offloading) flare tower by using a floating crane. The method comprises the following steps that the flare tower is overturned by using the floating crane under the assistance of a crawler crane in a flare tower hoisting area, then, the connection between the crawler crane and the flare tower is released, the floating crane is moved to move the flare tower to a position above a flare tower base on an FPSO, and then, the flare tower is slowly lowered, the flare tower gradually gets close to the flare tower base through chain blocks installed on the flare tower, and meanwhile, the flare tower is hoisted in place through constraint of guide plates installed on the flare tower base in advance, and finally, the flare tower is welded under the condition that the floating crane is kept in a hoisting state, after welding is finished, connection between the floating crane and the flare tower can be removed, and hoisting of the flare tower is finished. According to the method, the flare tower can be hoisted to the flare tower base through existing equipment, and welding of the flare tower and the flare tower base is completed.

Description

technical field [0001] The invention relates to a method for hoisting an FPSO flare tower with a floating crane. Background technique [0002] Since the height and weight of the flare tower of the floating production, storage and offloading device are relatively large compared with the flare arm on the platform, if the flare tower of the floating production, storage and offloading device is hoisted at the wharf, it is necessary to consider using a lifting equipment. [0003] If land cranes are used, it is difficult for ordinary wharfs to find existing lifting equipment suitable for flare tower hoisting. If temporary design and construction of lifting equipment suitable for flare tower hoisting is required, more investment will be added, and more importantly, the construction period will be affected. and other uncontrollable factors. At the same time, if the final placement of the flare tower is to be completed, the flare tower needs to be transferred from the horizontal po...
