摘　　要：南海西部某陆岸终端单点提油海管由于未设计收发球筒装置,无法进行通球内检测,导致不能及时发现海管存在的各种缺陷,存在重大安全环保隐患。针对单点系泊系统特殊结构,通过自主改造设计安装简易立式双向收发二合一球筒并新增供排水通球流程,实现了海管正反向循环通球内检测功能。通过该适应性改造,完成了海管首次内检测,发现海管主要缺陷为陆岸管段外腐蚀并进行了加固修复,保障了海管安全环保可靠运行,同时创造经济效益1100万元,对类似海管内检测适应性改造具有一定的借鉴意义。The single point oil extraction pipeline at an onshore oil terminal in the western South China Sea was unable to carry out through-ball internal inspection due to the lack of design of pig receiver and launcher device,resulting in the inability to timely detect different defects in the pipeline and the existence of major potential safety and environmental protection hazard.Aiming at the special structure of the single point mooring system,the simple vertical bidirectional two-in-one pig receiver and launcher was transformed,designed and installed independently,and the water supply and drainage process was added,which realized the pipeline internal inspection function of positive and negative circulation through-ball.Through this adaptive transformation,the first pipeline internal inspection was completed and it was found that the main defects of the pipeline was the external corrosion of onshore pipeline section and the reinforcement and repair were carried out,which ensured the safe,environmentally friendly and reliable operation of the pipeline.At the same time,it created the economic benefit of 11 million yuan and possessed reference significance for the adaptive transformation of similar pipeline internal inspection.
