Abstract

The invention discloses a manufacturing method of a cylinder body of an offshore wind power large-diameter thin-wall suction cylinder, and relates to the technical field of offshore wind power manufacturing. The manufacturing method specifically comprises the following steps: S1, a cylinder body is divided into eight sections, and all the sections are manufactured respectively; S2, each section is manufactured; S3, the interior of a single circle is strengthened; S4, vertical welding splicing is carried out; and S5, the rest of the cylinder body sections are assembled. The manufacturing method has the advantages that aiming at manufacturing of the cylinder body of the large-diameter thin-wall suction cylinder, the cylinder body is divided into eight sections to be manufactured respectively, the cylinder body sections at the end parts are internally reinforced, the structural strength is ensured, and smooth assembling, hoisting, transferring, turning over and other procedures of the cylinder body are ensured; and the vertical welding splicing is firstly carried out, and then the rest of the cylinder body sections are sequentially assembled, so that the manufacturing process is optimized, the production efficiency is improved, the assembly precision is improved, the safe construction is facilitated, and the quality stability is improved.

Description

technical field [0001] The invention relates to the technical field of offshore wind power manufacturing, in particular to a method for manufacturing a large-diameter thin-walled suction cylinder for offshore wind power. Background technique [0002] In recent years, the state has increased its support for offshore wind power projects, and my country's wind power industry is in a stage of vigorous development. In 2020, the country's first suction tube jacket was successfully installed offshore, marking the birth of a new type of offshore wind power jacket structure - the suction tube jacket. The application of suction cylinder technology in offshore construction has the characteristics of convenient installation, short cycle, convenient dismantling, no noise, no piling vibration, etc. It will effectively reduce the pollution of the marine environment during engineering construction, protect the ecological environment, and make positive contributions to the practice of green ...
