Cygnus Mini ROV Mountable

Multiple Echo Ultrasonic Thickness Gage

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).

Cygnus Instruments builds all of its equipment in the UK using only genuine and original parts and components – including Lemo® Connectors and Peli® Cases.

FEATURES

  • Designed specifically to mount onto small observation ROV’s.
  • Supplied with *CygLink software to display and log thickness measurements from the ROV on a computer at the surface which can be saved to a file and printed out.
  • CygLink has two data logging facilities: Quick Log for simple recording of thickness measurements and structured mode with four templates available – Single Point, Multi Point, Grid Point and Key Point.
  • Easy calibration at the surface via CygLink software or Top Side Repeater (TSR) unit.
  • Optional dedicated probe holder to allow measurements on curved or flat surfaces.
  • Only one twisted pair is required to transfer the data to the surface.

PROBE HANDLING SOLUTIONS

Cygnus G1 Observation, Inspection, Light Work Class ROV Probe Handler:  The Cygnus G1 Probe Handler is designed for use on Observation, Inspection and Light-work class ROVs. Constructed from acetal it is both strong and lightweight it features an adjustable mounting bracket allowing optimum positioning of the UT probe. The UT probe is located in an articulated mount that allows up to 15 degrees of movement in both planes allowing automatic alignment of the probe face to the measurement surface making the ROV pilot’s job easier.

Cygnus S1 Probe Handler for ROV Ship Hull Inspection:  Complementing the Cygnus range of ROV Mountable thickness gauges, the Cygnus S1 Probe Handler is developed for use on Inspection and Medium sized ROVs carrying out ship hull inspections.
