SEATRONICS SeaDTEC Diver Flooded Member Detector


The Seatronics SeaDTEC Diver flooded member detector is used by divers to determine if a subsea void is filled with a liquid or gas (up to the inspection point). The main advantage of the SeaDTEC is to determine whether a leak has occurred within subsea enclosures.

Delivery to be advised


Main components of the Diver Flooded Member Detector are the subsea electronics pod and hand held probe, 200m umbilical on cable reel, topside interface unit and control laptop.

The SeaDTEC is manipulated by the diver according to instructions given from a surface operator. A high frequency pulse is sent from the probe and if the member is flooded a reflected pulse from the opposite side of the member will be detected.

SeaDTEC software provides the surface operator with visual indication of the test results via an A-Scan display on a laptop. Results can be printed or saved to a log file which includes a record of the A-Scan display, Date, Time, Structure, Member, Orientation, Client and Test Engineer.
