ABS has published and issued guidance notes on structural monitoring using acoustic emissions. This guidance presents best practices for planning and executing acoustic emission testing.
“A primary goal at ABS is to improve safety without interrupting operations,” says ABS Chairman, President and CEO Christopher J. Wiernicki. “These new guidance notes provide a framework that will help companies perform acoustic emission testing in support of continuous health monitoring for their assets.”
Acoustic emission testing is a passive nondestructive examination technology that has been successfully applied to detect and monitor crack propagation, corrosion activity, cavitation erosion and leaking in structures made of steel, aluminum, composites and other materials. Acoustic emission testing is seeing increasingly widening applications in a number of industries as a feasible way to detect weaknesses and monitor structural health in a broad spectrum of structures from storage tanks, suspension bridges, nuclear plants, pressure vessels and LNG tanks to mooring chains and airplanes.
Ships and offshore structures continue to become larger and more complex, requiring operators to have an in-depth knowledge of structural integrity. The acoustic emission testing guidance notes address this need by providing a non-intrusive, real-time technique for monitoring structural health on an operating asset.
“As a technology leader, ABS recognizes the growing industry focus on digitization and more advanced monitoring methods,” says ABS Chief Technology Officer Howard Fireman. “The guidance notes address the latest technological shifts in industry, leveraging real-time monitoring to help owners and operators better understand the health of their assets and guide their maintenance and repair decisions.” This guidance was developed based on a series of joint industry projects in which owners, operators and ABS worked together to improve asset integrity applying this advanced health-monitoring technology.
