Sentry IMS is designed to provide fast automated warning of containment issues connected to subsea oil and gas installations and equipment, and is able to monitor over a billion cubic feet of seawater in a 360° envelope around a single sensor.
The active sonar system is based on proven offshore detection, localisation and classification sonar technology, and can detect the smallest of leaks at ranges exceeding 500 meters with low false alarm rates. Position data is automatically delivered to remote monitoring stations, and multiple sonar heads can be networked together to increase coverage.
Sentry is available in two configurations - a lander-mounted version that connects to existing seafloor communications infrastructure and power supply, and a standalone battery-operated system that transmits data via an acoustic modem.
