Cygnus ROV Mountable Subsea Ultrasonic Thickness Tester

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.
