Cygnus Instruments ultrasonic testing equipment enables fast and efficient maintenance to be performed on subsea structures and underwater equipment that include:

Such structures require specialised underwater inspection equipment to measure metal thickness in carrying out routine subsea maintenance checks and surveys.

Cygnus has a dedicated range of diver-held, wrist-mounted and ROV Mountable Multiple Echo ultrasonic thickness gauges. Cygnus understands the need for a rugged, reliable ultrasonic testing instrument that won't let you down in these hostile conditions, and our Cygnus Underwater gauge has been successful for over 20 years in taking accurate underwater thickness measurements.  It is one of our best sellers and is generally found as standard kit on offshore rigs and structures.

All Cygnus underwater gauges and ROV equipment can optionally relay thickness data to the surface (topside) for monitoring, recording or logging purposes.  Our Windows-based software offers a simple interface with the subsea equipment.
