Title: Yufeng Ouyang and Acoustic-Emission Detection for LNG Storage Tanks.

Introduction

Yufeng Ouyang is an inventor based in Beijing, China. His work includes a patented method for detecting leaks in full-capacity liquefied natural gas (LNG) storage tanks using acoustic emission. He is associated with the China Special Equipment Inspection and Research Institute.

Latest Patents

The provided information lists one patent for Ouyang: “Method for Detecting Leakage of Full-Capacity LNG Storage Tank by Acoustic Emission.” The method uses an acoustic sensor to measure system and ambient noise and establish a signal-acquisition threshold. It then compares signals from an analog sound source at different distances to calculate how sound attenuates through the tank’s outer wall. Based on those measurements, the method determines the sensor’s maximum detection range and guides its movement across the tank wall to inspect for LNG leakage. Ouyang’s reported portfolio includes 1 patent.

Career Highlights

Ouyang’s listed invention addresses leak detection in large LNG storage tanks, where reliable inspection is important for identifying potential containment problems. The method combines acoustic measurements, attenuation calculations, and a defined sensor-movement procedure.

Collaborations

The provided information names Yongna Shen and Gongtian Shen as Ouyang’s coworkers. It does not specify their roles in the patent or the extent of their collaboration.

Conclusion

Yufeng Ouyang’s reported patent applies acoustic-emission measurements to LNG tank leak detection, reflecting a focused contribution to inspection technology.
