This work explores the versatility of ultrasonic phased arrays for detecting cracks in fastener nuts in a deepwater environment using a remotely operated vehicle (ROV). Inspection solutions must overcome access and movement restrictions imposed on the probe by the ROV. Three approaches are proposed to address this problem using electronically moving apertures, beam steering and extensive use of multiple reflections from the hexagonal geometry. The approaches are tested both by simulations and experiments and an inspection strategy is outlined. [ABSTRACT FROM AUTHOR] |
