Flooded Member Detection is an inspection regime designed to screen subsea platform structural members for leak defects. A cracked weld can allow the ingress of sea water into the member which may create a point of failure for the structure. There are two recognized non-destructive testing (NDT) techniques that allow for Flooded Member Inspection; the use of a radioactive source Gamma Radiography, or by using Ultrasound.

The new Cygnus Flooded Member Detector (FMD) is a complete ultrasonic system specifically designed for checking whether a member/pipe is flooded. The FMD is designed for subsea inspection and comprises three parts; the probe/probe handler, subsea electronics unit and reporting software. The FMD probe handling solution self aligns, ensuring correct contact with the member, even when approached from an angle. The system also has a contact sensor which will not allow a test to be taken unless the probe is correctly aligned. A simple DRY/FLOODED result is sent to the reporting software with results logged at the surface.

The Cygnus FMD system is easy to use, cost-effective, rugged and reliable. Available in either high grade acetal or stainless steel for the harshest environments the FMD system is designed to the highest specifications and is supported by a three year warranty.

Inspection using a radioactive source is effective, however the equipment is almost always provided as a service by a third-party contractor and to operate the equipment one, or often two, specialist technicians must travel with the equipment – thus taking up precious bed-space offshore. The Cygnus Ultrasonic Testing (UT) FMD system is simple to operate and thus allows for existing staff from the diving/ROV team to perform the inspection work themselves. This provides a significant cost-saving in personnel. In addition, the operator can perform small packets of FMD inspection work when required as the vessel is not tied to meeting a third-party inspection service provider offshore at a certain time or place. With the Cygnus FMD system, work can be done as and when it is required.

The Cygnus FMD system is the only system that is designed by specialist ultrasonic testing experts. Cygnus has been in the underwater inspection business for nearly 4 decades.

The Cygnus FMD also has a 4-way gimble built around the transducer to ensure correct transducer alignment and a transducer contact sensor to alert the topside technician to the fact that the ROV or diver has made good contact. Furthermore, the Cygnus FMD system’s advanced signal processing and low noise data acquisition will work on thick-walled members and pipes (up to 75mm thick), on heavily corroded members and on buoyancy tanks.
