Leak Detection
When discussing leak detection, two scenarios are apparent:
Emergency Leak Detection
In pipelines or any sub sea production facility.
If that scenario occurs, a combination of 1200/400 kHz sonar can be mobilized on an ROV that will go find the leak. RESON did that successfully with a 455 kHz imaging sonar in the GOM, where a pipeline was pressurized to 2200 psi using fresh water. The pipeline however, could not hold pressure. A leak was found at 2000m of water, where fresh water was detected leaking into sea water at 2200 psi.
Permanently Installed Imaging Sonars on Production facilities
RESON has seen a growing interest for permanently installed imaging sonar systems on production facilities.
Over the last two years a number of incidents have occurred in the North Sea where both gas and oil leakages have occurred without being detected before being at surface level.
Imaging sonar technology can be installed on a template and be tied back to a production platform, and automatically generate an alarm if a leak occurs. The leakage can be any of the following:

- Gas
- Oil
- Hydraulic Oil
Compared to these recent incidents in the North Sea, especially gas leakages detected on platform deck levels by the crew on the platform, it is obvious that safety can be greatly improved.
