Cygnus in successful collaboration with Deep Trekker

15th July 2021

Cygnus Instruments, UK, reports that it has been working with Canadian ROV and crawler manufacturer Deep Trekker to achieve full integration of the Cygnus Mini ROV Mountable thickness gauge with Deep Trekker’s polyvalent ROVs.

The Mini ROV Mountable thickness gauge has been specially designed to be mounted onto small observation ROVs with or without a manipulator facility, according to Cygnus.

Cody Warner, Deep Trekker’s sales manager, said: “Cygnus Instruments is recognised as the leading name in subsea thickness testing and the Mini ROV ultrasonic thickness (UT) gauge has proven itself time and time again and over many years in the subsea industry. We are delighted that this UT gauge is now available on our ROVs. It has already been successful in multiple different applications with many Deep Trekker customers; the feedback has been extremely positive.”

Cygnus said: “Mounted on the highly capable Deep Trekker ROVs, the Mini ROV UT gauge will allow the operator to carry out an ultrasonic thickness measurement in areas that have previously been unfeasible using larger ROVs or divers. The unit has the famous ‘multiple echo’ technique at its core; the advantages of which include extremely fast and accurate measurements – as well as the ability to ignore coatings up to a half of an inch (12 millimetres) thick.”

The unit is pressure tested to 1640 feet (500 metres).


Cody Warner added: “Our customers need more than just visual data to confirm structural integrity and identify where to invest repair dollars. Ballast tank baffles, intake structures, vessel hulls, and potable water tank walls are just a few of the structures where our operators have used the gauge to safely gather thickness data – instead of having manned entry with divers. Gathering the data is really easy and reliable, whether it is conducting a quick spot check on a suspected spot or getting a profile of a whole structure.”
