摘要：
As the offshore life and production base,the offshore platform plays an important role in offshore oil exploitation.The acoustic emission(AE)technology can be applied to damage detection and early warning of the offshore platform,and then can effectively guarantee the safe operation of the offshore platform,prevent accidents and casualties.The steel jacket offshore platform is currently the most widely used in shallow sea oil field of our country.Considering the complex structure of the steel jacket offshore platform and using AE technology,this paper has carried on research on effects of the pipe diameter size,the welding angle on the AE signal propagation characteristics,and at the same time,influence of the marine environment(seawater temperature,salinity)on the AE testing.These research contents have very important reference value for the application of the AE technology in offshore platform monitoring.
