Cygnus FMD System for ROV
Ultrasonic Flooded Member Detector
The FMD system comprises the probe with probe handler, the subsea electronics unit and the reporting software. An ultrasonic flooded member detection is operated from the FMD reporting software at the surface. Once correct alignment is detected by a contact sensor, a test can be performed and the system will give a simple Dry (Green) / FLOODED (Red) result along with A-scans.
EASY TO USE
The Cygnus FMD has an innovative probe handling solution which self-aligns, ensuring correct contact with the member, even when approached from an angle.
The system returns a simple DRY / FLOODED result to the reporting software with results logged at the surface.
The Cygnus FMD System is owner operated and extremely easy to learn and understand.
Due to its simplicity and innovative fail safe design the FMD system can be used by a range of operators, with varying experience, without the need for external contractors.
Available in high grade acetal or stainless steel for the harshest environments.
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 system will only take a measurement when the contact sensor detects probe contact, ensuring reliable results every time. The reporting software will indicate at the surface should the probe lose contact during a test.
System Test Function ensures the reliability of the system before it is deployed.
Being of a compact design the probe is able to get into hard to reach areas, such as K nodes, where other inspection methods cannot. A range of versatile options to suit working depths and varying requirements are available.
The same FMD system is also diver deployable.
