AAn Investigation into the Impact of Fishery on Buried Depth of Subsea Pipeline

摘要

Fishing activities as well as other thirdparty factors can have great impact on the safety of subsea pipelines. Through an investigation into fishing activities in different sea areas in China, combined with theoretical and modeling calculation of the actual influence of the impacting trawl board and anchor on pipelines, a recommended under bed solution of subsea pipeline was worked out. The solution can provide reference in rule-making involving the burial depth of subsea pipelines.
