Reinforcing Subsea Asset Integrity With Ultrasonic Testing

Thriving from its roots in marine inspection services, Cygnus has been a trusted brand for extremely reliable and easy-to-use ultrasonic thickness measurement (UTM) equipment for infrastructure above and below water.

Two impressive subsea ultrasonic thickness gauges - Cygnus Dive and Cygnus ROV UTM, boast multiple advanced features specifically designed for:

Ship Hull UTM Inspection
Civil Engineering
Inspection, Repair and Maintenance (IRM) of Marine Infrastructure
Mobile Offshore Units (MOUs), e.g. offshore platforms and FPSOs
Underwater Pipelines and Equipment
Vessel UWILD or IWS Surveys

Cygnus Dive - The shining star of the Cygnus Subsea Range

Cygnus Dive - a robust, wrist-mountable UT gauge, was designed to aid divers in harsh subsea situations by freeing up an invaluable hand to perform ultrasonic thickness measurements underwater.

It is now our most popular diver gauge. With its large, bright display with Live A-scan, measurements are easily viewable to the diver and camera crew, even in poor visibility. The gauge can measure various surfaces and materials using Cygnus’ Multiple-Echo mode for accurate through-coat measurements (as specified by Classification Societies) and Single-Echo & Echo-Echo modes for extreme corrosion. Other options include data-logging with Auto-Log (storing up to 5000 readings with A-scan graphs); a range of ultrasonic probes to suit different applications; topside repeater facilities, and finally, the HelmetView® - a clever remote display that sits flush on the outside of the diver’s helmet and allows the diver to see the measurement being taken without needing to look down - especially useful in ultra-low visibility or “black water”.

Cygnus ROV UTM - The only ROV Ultrasonic Thickness Gauge with live A-scan

This dedicated ROV-mountable, highly intelligent ultrasonic thickness gauge is purpose-built for measuring metal thickness in the harshest subsea operating conditions, up to 3,000m deep. Equipped with Cygnus’ Multiple-Echo technology and Echo-Echo measuring modes, it fits the bill for accurate measurements through coatings, as specified by Classification Societies - reducing time and costs. With the integration of Live A-Scan, users can achieve advanced verification of measurements through detailed visual analysis at the topside. Combined with a high-performance piezo-composite probe and auto-selection of an optimal measuring mode, this ultrasonic thickness gauging equipment delivers exceptional corrosion/thickness inspection accuracy and efficiency.

It’s easy to see why Cygnus ultrasonic thickness gauges are ideally suited to performing Class surveys and subsea inspection, repair, and maintenance (IRM) of underwater infrastructure and Mobile Offshore Units (MOUs).
