Cygnus FMD System for Diver
Ultrasonic Flooded Member Detector
Once the subsea units are deployed, Cygnus FMD system runs a test using the FMD reporting software at the surface and shows a simple DRY (Green) or FLOODED (Red) result with A-scans for further verification. The results are logged for analysis or reporting as PDF and Excel.
EASY TO USE
The agile probe handling solution self-aligns with the surface and ensures correct contact with the member – regardless of what angle or direction of approach.
A simple DRY / FLOODED result is displayed and logged at the surface on the reporting software.
Due to its clever and failsafe design, this system is very easy to learn and can be used by owners or operators with varying experience – without the need for external contractors.
The FMD equipment is designed to the highest standards, supported by a three year warranty.
The purpose-designed algorithm simultaneously uses:
- advanced signal processing
- an advanced peak detection algorithm
- low distortion / low noise data acquisition
to ensure highest level of Probability of Detection (PoD) to eliminate false readings.
The failsafe design also means a measurement is only taken when the contact sensor detects correct probe contact and alignment.
Any loss of contact is shown on the reporting software at surface.
System Test Function enables a test prior to deployment.
The compact design of the probe solution means tests can be done on hard to reach areas such as K nodes where other inspection methods are unable to perform.
A range of versatile options are available to suit working depths and varying requirements.
This FMD system is also deployable by ROVs.

The new Cygnus Ultrasonic FMD System was perfect for our recent application. Our technicians found the software to be very easy to use with features that ensured a quick and reliable result. It’s a great addition to the Westerton Access capability, offering FMD inspection from the Falcon ROV
