ROV ultrasonic thickness gauge
22/04/2022
Cygnus Instruments has introduced the Cygnus ROV UTM, a remotely operated vehicle (ROV) ultrasonic thickness gauge with live A-scan.
This dedicated ROV-mountable highly intelligent ultrasonic thickness gauge is specifically designed to measure metal thickness in the harshest subsea operating conditions. Equipped with Cygnus’s multiple-echo (ME) technology and echo-echo (EE) measuring modes, it offers accurate measurements through coatings (up to 1 mm), as specified by classification societies, reducing time and costs.
Integrating live A-scan drives the Cygnus ROV UTM forward, achieving more advanced verification of thickness measurements through detailed visual analysis at the topside. Not only this, but the gauge performs at an impressive depth of up to 3000 m. Combined with a high-performance piezocomposite probe, this thickness gauging equipment delivers excellent inspection accuracy and efficiency.
The addition of echo-echo and single-echo (SE) measuring modes opens up further opportunities for measuring challenging materials, in particular heavily corroded metals with largely worn or no remaining coating. Operators can manually select a measuring mode or use the Auto SE/EE/ME mode, which automatically selects an optimal measuring mode for best measurement results.
The system comes ready to go with CygLink software to display and process measurements on a computer at the surface, while supporting easy-to-use calibration and measurement settings.
The Cygnus ROV UTM is manufactured in the UK and now holds the UKCA mark.
Compatible with a choice of T-bar or fishtail manipulator handles, the P50 probe handler is cleverly designed to self-align the ultrasonic probe onto straight pipes, from 50 mm-diameter to flat surfaces. The spring-loaded probe and V-shaped block ensure the probe is positioned correctly and accommodate different pipe diameters. The gimbal allows the probe to move to align onto the straight pipe surface when used with an ROV manipulator arm.
