A kind of hoisting and transportation technology of flare tower

Abstract

The invention relates to a torch tower hoisting transportation process. Upper lifting lugs are mounted on a torch tower; then the torch tower which is assembled on the bed-jig is hoisted and leaves abed-jig through a gantry crane; the torch tower is lifted and put on a wharf, and the total section of the torch tower is put longitudinally; then the gravity center of the torch tower is moved forwards by cooperation of the gantry crane and a floating crane, and the front section of the torch tower extends out of the wharf; and a hook is put on the floating crane again and hoists the torch tower,the torch tower is hoisted and put on a barge, and the torch tower is transported to the destination through the barge. The torch tower hoisting transportation process has the advantages that throughcooperation of the gantry crane, the lifting lugs and the floating crane, the torch tower on the bed-jig is hoisted and carried to the barge for transportation, accessories such as a main hoisting beam and an auxiliary hoisting beam are not needed, great conveniences are brought, after hoisting is performed through the lifting lugs, the lifting lugs can be directly mounted on the torch tower without affecting usage of the torch tower, thus disassembling is not needed, and manual work is reduced.

Description

technical field [0001] The invention relates to a flare tower, in particular to a flare tower hoisting and transportation process. Background technique [0002] With the development of the world's industrial economy, deep-sea oil fields are gradually being developed, and the demand for FPSO ships (Floating Production Storage and Offloading floating production storage and offloading devices) and other corresponding offshore engineering products continues to increase. Flarestack is a unique structure on FPSO. It is a device for treating exhaust gas by open-air combustion, and it is also an important equipment in offshore oil and gas production systems. The layout of the flare tower on the deck has been specially considered. It is generally installed at the head of the upper deck of the FPSO, away from the safe area. It is a truss structure welded by steel, consisting of columns, triangle braces and diagonal braces. An inspection platform is set on the top. The column, triangu...

Problems solved by technology

[0004] However, in the process of hoisting the flare tower, the above-mentioned hoisting process also needs to build additional accessories such as main hanging beams and auxiliary hanging beams, which is very troublesome, high in cost, and is easily limited by the site. After the hoisting is completed, the main hanging beam and other accessories need to be removed, which is labor-intensive
