Krishnan Balasubramaniam, Institute Chair Professor and Dean at the Indian Institute of Technology Madras, will deliver the plenary address, “New Approaches to Asset Management using Novel NDT Tools,” Thursday at 8:00 a.m. in Ballroom A-B.
Balasubramaniam’s research interests include ultrasonics and acoustics, structural health monitoring, micro- and nanoimaging, nondestructive evaluation, materials characterization, and wave propagation. His presentation will focus on corrosion, which he says is the single most critical damage mechanism that influences the profitability of a wide range of industries. His presentation will cover advanced guided wave–based ultrasonic methods using both short-range guided waves using higher order modes cluster (HOMC) techniques for the detection of corrosion in tank bottoms and pipe support/interface locations, and the long-range ultrasonic guided wave pipe monitoring (GuMPS) technique for the continuous monitoring of corrosion in insulated high-temperature pipes.
Using waveguide sensors for distributed process monitoring will also be discussed. Similarly, for both underwater and aboveground installations, ROVs (remotely operated vehicles) and intelligent drones can provide visual, ultrasonic, and thermal data at a relatively low cost and in a rapid manner.
Using the techniques presented at the lecture, Balasubramaniam will show how these techniques have unique capabilities for monitoring different components and must be designed and implemented based on the specific application, and explain how operator/owners can make vital decisions regarding component integrity and propose necessary repair/replacement or estimate the remaining life of the components that are subjected to corrosion in the invisible regimes of the facility.
