Analysis on sediment types and erosion and deposition changes of the submarine pipeline
The submarine gas transmission pipeline must withstand the changes of the submarine environment.If a pipe-line safety accident occurs,it will bring huge losses.During the work,the types and distribution of submarine sediments within the submarine pipeline route corridor area are analyzed through scheme design,data collection,field investigation,sample collection,laboratory testing,data analysis and sorting,etc.At the same time,the change characteristics of the coastline and seabed in the route area are studied through map comparison and data analysis,and the stability of the sea-bed in the project area is judged,which is helpful for pipeline engineering design The selection of protection scheme pro-vides basic data to ensure the long-term operation stability of the pipeline on the seabed.
