摘要

Submarine pipeline has been widely used in offshore oil and gas transportation due to its advantages of high transportation efficiency, large capacity and being unaffected by weather. Anchoring is one of the main causes of submarine pipeline damage, which may cause impact damage to the pipeline, and then pollute the Marine environment. In this paper, the effect of anchoring penetration depth on buried depth of a liquefied natural gas transportation pipeline is studied based on the actual project. In terms of anchor dropping, the applicable conditions and calculation results of Japanese anchor dropping experiment and ABAQUS finite element method are compared. The empirical prediction method, API 2SK standard prediction method and finite element method were used to study the penetration depth of the anchor. The finite element calculation results were accepted after comparative analysis. Finally, the reasonable buried depth value of engineering pipeline is obtained by combining the existing buried depth design method proposed in this paper. Relevant methods and research results have important guiding significance for the design of submarine pipeline burial depth and pipeline damage assessment of similar projects.
