With the continuous development of offshore oil and natural gas resources,the importance of offshore platform pressure pipelines is also increasing.They play a key role in the process of transporting oil and gas from the wellhead to the export pipeline.However,due to the special environment and complex medium conditions of offshore platforms,these pipelines are very susceptible to damage and destruction,which not only leads to resource leakage and environmental pollution,It will also pose significant risks and threats to the safety and operational stability of offshore platforms.Therefore,it is necessary to identify and analyze common damage modes of offshore pressure pipelines,and then develop special protection and treatment strategies.
