Abstract： In order to study the corrosion defect repair technology and its construction process quality control, based on the analysis of the corrosion environment and protective layer, the corrosion defects of the riser in Bohai are analyzed. From the aspects of riser base surface treatment, corrosion and anticorrosive ointment filling, viscoelastic tape winding, the winding of PVC protective belt, and the winding of water curing epoxy glass steel belt, we introduce the sea pipe repair key technology and construction technology of riser. At the same time, after detailedly introducing the riser repair construction quality control, the riser repair reinforcement scheme, surface treatment, construction technology, detection technology, site restoration and other aspects are described for the overall quality control.
