Cygnus FMD System for ROV for Accurate Flooded Member Detection in Subsea Structures

When you’re responsible for subsea structures, uncertainty is expensive. A flooded structural member isn’t something you can see from the outside, but it can quietly weaken the integrity of your asset over time.

Sending divers down for manual checks takes time. ROV operations are costly. And making assumptions about whether a member is dry or water-filled simply isn’t acceptable when safety, compliance, and uptime are on the line.

The Cygnus FMD System removes the guesswork from subsea inspections. It provides a clear answer, dry or flooded, so your team can make fast, confident decisions offshore.

There’s no complicated data to sort through and no unnecessary repeat inspections. Just reliable results that help you reduce risk, control costs, and protect critical infrastructure underwater.

Self-Aligning Probe and Fail-Safe Contact Sensor for Reliable Subsea Flooded Member Detection

The Cygnus FMD System is engineered for dependable subsea inspections with its intelligent self-aligning transducer handler and fail-safe contact sensor.

The self-aligning probe automatically adjusts to the surface of the structural member, eliminating the struggle of awkward ROV positioning and ensuring secure, consistent contact, even in hard-to-reach areas like K nodes.

This design significantly reduces maneuvering time and helps operators maintain stable measurements in challenging underwater environments.

To further protect inspection accuracy, the built-in fail-safe contact sensor prevents a reading from being taken unless the probe is properly aligned and physically touching the structure.

If contact is lost during testing, the surface software immediately alerts the operator, preventing false readings and wasted dive or ROV time.

Together, these features increase Probability of Detection (PoD), reduce costly rework, and give subsea inspection teams greater confidence in every flooded member assessment.

Clear DRY/FLOODED Interface with Automated A-Scan Reporting for Subsea Inspections

The Cygnus FMD System simplifies complex subsea ultrasonic testing with its clear DRY/FLOODED visual interface and integrated A-scan display with automated reporting.

Instead of forcing operators to interpret complicated NDT waveforms, the software translates inspection data into an intuitive color-coded result: DRY (green) or FLOODED (red).

This dramatically reduces ambiguity, allows for faster offshore decision-making, and makes the system practical for owner-operators without the need to hire specialized external analysts.

For validation and documentation, the system simultaneously displays a verifiable A-scan and automatically logs every test performed. The FMD Reporting Software stores raw data for offline analysis and enables instant generation of professional PDF or Excel reports.

This streamlines compliance documentation, reduces administrative workload, and ensures every flooded member inspection is backed by traceable, reviewable ultrasonic data.

Cygnus FMD System for ROV with Advanced Detection Algorithm and Rugged Subsea Construction

The Cygnus FMD System is powered by an advanced data processing algorithm designed to maximize inspection accuracy in demanding subsea environments.

Using advanced peak detection, low-noise and low-distortion data acquisition, and specialized signal processing, the system delivers a high Probability of Detection (PoD) while actively reducing the risk of false readings. This gives operators greater confidence in flooded member inspections and helps prevent costly misjudgments that could lead to unnecessary repairs or overlooked structural risks.

Supporting this performance is a ruggedized acetal construction built specifically for harsh underwater conditions. The subsea electronics unit and transducer handler are manufactured from high-grade, lightweight acetal to withstand pressure, impact, and long-term exposure to marine environments.

Backed by a three-year warranty, this durable design ensures long service life and dependable operation, reducing downtime and protecting your investment in subsea inspection equipment.

Flexible ROV or Diver Deployment with Pre Deployment System Testing for Confident Subsea Inspections

The Cygnus FMD System offers compact, versatile deployment by ROV or diver, giving subsea inspection teams the flexibility to adapt to virtually any offshore environment. Its compact probe design allows access to confined and complex areas such as K nodes that traditional inspection tools often cannot reach.

This dual-deployment capability improves operational efficiency, expands accessibility, and supports a wide range of subsea inspection, repair, and maintenance programs without being limited to a single method of deployment.

To further protect your time and budget, the system includes a dedicated pre-deployment system test tank and integrated software test function that verifies full functionality before the equipment enters the water. This prevents costly delays associated with discovering issues mid-operation and ensures the system is fully operational before committing to expensive dive or ROV time.

If you are looking to reduce risk, improve inspection reliability, and gain greater confidence in flooded member detection, the Cygnus FMD System is ready to support your next subsea project.
