For measuring metal thickness through paint at depths of up to 500 meters and in the harshest subsea operating environments, this ROV mountable ultrasonic thickness tester has been designed to be mounted on to large work class remotely operated vehicles. And as with all Cygnus metal thickness testers, the ROV ultrasonic thickness tester uses the Multiple-Echo technique for accurate and self-verified readings without having to remove protective coatings.
Key Features of the Cygnus ROV Mountable Tester
- Multiple-Echo mode for accurate, through-coat measurements as specified by Classification Societies
- Supplied with CygLink software to display and process measurements on a computer at the surface
- Selectable Deep-Coat mode ignoring coatings up to 20mm thick
- Fitted with a safety Pressure Relief Valve and Securing Eye
- Easy calibration at the surface via CygLink software or TopSide Repeater (TSR) unit
- Removable end plate for full serviceability
- Wet mateable ‘MC’ style underwater connectors.
- Optional Topside Repeater (TSR) unit allowing readings to be displayed remotely and superimposed onto ROV’s camera screen
- Optional purpose-built ROV probe handlers for optimal alignment.
Cygnus-Pioneered Multiple Echo Technique
- 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
- Echo strength indicator to aid measurement.
CygLink Computer Software
CygLink is a Windows® application that allows remote viewing, control and data logging of the ROV tester. The software can generate survey reports in PDF or export to a CSV file. Designed for Windows® 7 and above.
The latest version of CygLink software is available to download from ‘Software Downloads’.

Options
Engineered Probe Handling Solutions
To complement the Cygnus ROV Mountable ultrasonic thickness tester, Cygnus have engineering optional probe handlers:
- W1 constructed from 316 stainless steel and ideal for use on Work Class ROVs
- S1 and G1 designed for use on observation, inspection and light work-class ROVs.
TSR Remote Display Unit
The TSR is a remote display unit connected to the tester using an umbilical cable and displays thickness measurements at the surface, in real-time, during the ROV IRM (inspection, repair and maintenance) in water survey.
TSR with Video Overlay
The TSR can also overlay the real-time thickness measurements on to a composite video signal, displaying it on the survey monitor screen. It will also then be recorded (if there is a video of the survey), showing exact locations and the thickness measurement for future reference.
