Research Progress of Underwater Non-destructive External Inspection Technology
Non-destructive testing technology is used to find structural damage of underwater structures to avoid major accidents,which is very important to ensure the safe and reliable operation of offshore oil fields.External inspection technology is widely used in the inspection of underwater structures,such as jackets and submarine pipelines.This pa-per summarizes the technical characteristics of underwater non-destructive external inspection including eddy current inspection,ultrasonic inspection and ray inspection,as well as the technical parameters of corresponding underwater inspection equipment.Through comparative analysis of various inspection technologies,the advantages and scope of ap-plication of each inspection technology are mastered,and it is expected to provide technical reference for the engineer-ing application of underwater nondestructive inspection technology in our country.
