Cygnus Mini ROV Mountable

Ultrasonic Thickness Gauge

Specially designed to be mounted onto small observation ROVs with or without a manipulator facility. This subsea thickness gauge allows the operator to carry out an ultrasonic thickness measurement in areas that have previously been unfeasible using larger ROVs or divers - and no need to remove coatings!

The Cygnus Mini ROV Mountable thickness gauge has been specially designed to be mounted onto small observation ROVs with or without a manipulator facility. Built in conjunction with VideoRay, this subsea thickness gauge will allow the operator to carry out an ultrasonic thickness measurement in areas that have previously been unfeasible using larger ROVs or divers. And no need to remove coatings! Ideal for use in UWILD or IWS class surveys, subsea inspection, repair and maintenance (IRM) of infrastructure and underwater equipment.

Key Features:

  • 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
  • Easy calibration at the surface via CygLink software or Topside Repeater (TSR) unit
  • 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.

Engineered Probe Handling Solutions

Complementing the Cygnus Mini ROV Mountable thickness gauge, the Cygnus G1 is designed for use on observation, inspection and light workclass ROVs whilst the S1 probe handler is developed for use on ROVs performing UTM surveys on ship hulls.

Topside Repeater Remote Display Unit

The Cygnus Topside Repeater is a remote display unit connected to the gauge with an umbilical cable. It displays the thickness measurements at the surface in real-time during the survey.

Topside Repeater with Video Overlay

The Topside Repeater 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.
