The Cygnus Mini ROV Mountable thickness gage has been specially designed to be mounted onto small observation ROVs with or without a manipulator facility. Built in conjunction with VideoRay, this mountable subsea thickness gage will allow the operator to carry out an ultrasonic thickness measurement in areas that have previously been unfeasible using larger ROVs or divers. The multiple echo thickness gage measures metal thickness and corrosion without removing protective coatings.

Dedicated software displays the time, date and thickness readings on the surface which can all be stored or logged. Alternatively, an optional Topside Repeater (TSR) is available which has the facility to display the thickness measurements remotely and overlay them on to a video signal. This allows the measurements to be superimposed on the ROV camera’s monitor screen. 

The unit is pressure tested to 1,500 ft (500 m).
