Cygnus ROV UTM

Ultrasonic Thickness Gauge

This dedicated ROV mountable thickness gauge is depth rated to 3,000m, has live A-scan, a piezo-composite probe and self-aligning probe handler.  This ROV UTM deep water underwater thickness gauge is versatile and designed to measure metal thickness in the harshest subsea operating conditions - without the need to remove coatings.

Key Features of the Cygnus ROV UTM Gauge

  • A-scan to assist with measurement verification visually
  • Multiple-Echo and Echo-Echo modes for accurate measurements through coatings (up to 1 mm) as specified by Classification Societies
  • Single-Echo mode for heavily corroded metals with no coating
  • Use the Auto Single-Echo / Echo-Echo / Multiple-Echo measuring mode for best results or set manually
  • Supplied with CygLink software to display and process measurements on a computer at the surface
  • High-performance SD2C probe fitted with a Hard Rexolite Delay line
  • Easy calibration and measurement settings via CygLink software at the surface
  • P50 Probe Handler cleverly-designed to self-align with pipes from 50 mm diameters to flat surfaces
  • Manual or automatic gain control.

Benefits of Multiple Echo

  • Measures remaining metal thickness on corroded and coated structures
  • All measurements are error checked using 3 return echoes to give repeatable, reliable results
  • Accepted by all major classification societies
  • Greatly reduces inspection time and costs.

Probe Handling Solutions

The ‘P50’ Probe Handler is designed to align the ultrasonic probe on to straight pipes, from 50 mm in diameter up to flat surfaces.

The spring-loaded probe and v-shaped block allow the probe to be positioned correctly on a straight pipe and move to accommodate different pipe diameters.

A gimbal allows the probe to move to align on to the straight pipe surface when used with a ROV manipulator arm.

The probe handler can be fitted with a choice of manipulator handles; T Bar or Fishtail.

Cyglink Computer Software

CygLink is a Windows® based application for topside computer use to display continuous A-Scan output and measurement data. CygLink has the facility to log both data formats into a Survey file for report presentation, which can be emailed, exported as a PDF, or printed.
