海底管道安装完成后要进行清管试压，清管试压是检验海底管道系统施工质量的重要依据。结合工程实践，提出了适合于浮筒式多点系泊海底管道系统的清管试压技术，并对关键的操作要点和控制措施进行了研究，可为同类工程技术提供参考。
After the installation of the submarine pipeline was completed, the pigging and pressure test was carried out. The pigging and pressure test was an important basis for testing the construction quality of the submarine pipeline system. Combined with the project practice, the pigging and pressure test technology suitable for CBM submarine pipeline system was put forward. The key operation points and control measures are expounded. It provides a reference for other relevant engineering and technical personnel.
