Sensing solutions for assessing and monitoring underwater systems

P. Rizzo,    University of Pittsburgh, USA


Infrastructures containing or surrounded by water are an important aspect of modern civilization. Most of them operate under harsh environmental conditions. The periodic inspection or permanent monitoring of wet structures is therefore necessary. This chapter reviews the most common nondestructive evaluation (NDE) and structural health monitoring (SHM) methods for underwater structures. First, the structures and the challenges associated with their inspection are introduced. Then, the NDE techniques of visual inspection, magnetic particles, ultrasonic testing, sonars, radiography, and electromagnetism are illustrated. Finally, ...
