Many leaks go undetected by conventional pressure detection means, and subsea operators are facing tighter environmental regulations. Weatherford's SeaHawkTM subsea video surveillance and oil and gas leak detection system was developed to help operators stay profitable and environmentally compliant without adding downtime to the operation.
This system, developed through an operator's request, incorporates a high quality video camera, advanced LED lighting, monitoring software, and an open communication system. The system enables operators to detect the smallest changes, such as bubbles of gas or drops of oil. The advanced LED lighting system is vital to illuminating the dark environments, monitoring up to 33 feet away. Tying it all together is an open-communications technology for efficient data transfer from the hub to the surface facility.
The pattern recognition software does not mistake a fish swimming into view with a leak on the wellhead. When an event occurs that has the right size, orientation and duration of a leak, the software instantly recognizes this anomaly and sends out an alarm.
The video surveillance system is used for a range of monitoring applications. Environmental monitoring includes oil-and-gas-leak monitoring and detection, while condition monitoring incorporates subsea structural analysis, vibration analysis for slowly vibrating objects on the subsea structure and valve-position verification for valves without position feedback.
