AI Technical Summary
The welding quality of existing offshore wind turbine jackets is poor and the efficiency is low. In particular, during vertical welding, the crane is affected by wind speed, resulting in inaccurate positioning and requiring repeated adjustments.
The assembly and welding method using jacks is employed, with alignment assisted by annular assembly plates and shims. Welding is carried out in sections and rigorous testing is performed, including step-by-step welding of the inner ring, outer ring, and intersecting welds. Hydraulic lines and support structures are used to improve alignment accuracy and stability.
It improves welding quality and efficiency, reduces the impact of thermal stress, ensures the stability and precision of the welding process, and increases equipment utilization.
