Abstract: Take the route survey scenario of Aoshan-Cezidao-Zhenhai Submarine Oil Pipeline as an example, this paper determines the investigation method for this pipeline. The scenario divides the pipeline route into A, B, C, D and E section. From the landing section investigation, geophysical survey, geological reconnaissance, meteorological-hydrogeological dynamic environment observation, calculation on design factors and corrosion factor determination, this paper introduces the investigation and survey method of submarine oil pipeline and cites the investigation and survey report to be submitted.
