Jacket assembling method adopting standardized nodes

Abstract

The invention relates to a jacket assembling method adopting standardized nodes. The jacket assembling method comprises the following steps: prefabricating a main facade frame of a jacket; prefabricating horizontal layer flower pieces of the jacket; prefabricating a main vertical face X pattern supporting piece and a side vertical face X pattern supporting piece of the jacket; and horizontally assembling the prefabricated main vertical face frame, the horizontal layer flower pieces, the main vertical face X supporting flower pieces and the side vertical face X supporting flower pieces of the jacket to complete the assembly of the main body frame of the jacket. The jacket is split into the standardized series of pipe joints and rod piece sections, the standardized series of pipe joints and rod piece sections can be prefabricated in batches in a factory and then are welded and assembled in a construction site, the joints and rod pieces are assembled and welded in the construction site, automatic welding can be achieved, and the construction period can be greatly shortened.

Description

technical field [0001] The invention relates to a jacket assembly method using standardized nodes, and relates to the technical field of offshore oil and gas development. Background technique [0002] In the traditional jacket construction mode, the rods are prefabricated and lengthened at the construction site, and a plurality of extended rods are welded into a sheet frame, and the multiple sheet frames are finally welded into the main structure of the jacket; Welding, especially the welding of high-altitude joints, is very difficult and requires high welding quality. The joint welds are hyperboloid saddle welds, which require manual welding, and the post-weld inspection procedures are complicated. The traditional jacket site construction mode has complicated procedures and long construction time. [0003] At present, the jacket of Bohai has achieved standardized design, and the standardized design has greatly reduced the design period, but the traditional construction mod...

Problems solved by technology

[0002] In the traditional jacket construction mode, the rods are prefabricated and lengthened at the construction site, and multiple lengthened rods are then welded into a sheet-like frame, and the multiple sheet-like frames are finally welded into the main structure of the jacket; among them, the joints Welding, especially the welding of high-altitude joints is very difficult and requires high welding quality. The joint welds are all hyperboloid saddle welds, which require manual welding, and the post-weld inspection procedures are complicated

The traditional jacket site construction mode has complicated procedures and long construction time

[0003] At present, the jacket of Bohai Sea has achieved standardized design, which has greatly reduced the design period, but the traditional construction mode has not gained dividends from the standardized design
