Asset Integrity Confidence
Innovative passive systems help operators continuously monitor and manage the integrity of subsea oil and gas and carbon storage assets - lowering risk, reducing costs, and supporting compliance.
We are committed to delivering subsea integrity confidence while simplifying operations for operators.
Technologies
Passive Integrity Monitoring and Early Detection Technology
Chemomechanical WellSentinel™ and SAFE Disc™ passive technologies are easily deployed onto subsea assets, offering effortless remote monitoring and early leak detection, without the need for complex intervention, active subsea power or ongoing data communication.
Passive Trigger Detection and Alert
Sentinel utilities our chemomechanical proprietary Passive Trigger technology.
In the event of an emission, the system passively detects it using specially developed Triggers. These Triggers are designed to detect the presence of oil, thermogenic gas, CO₂, and other fluids in the subsea environment.
Deployments
REAL WORLD APPLICATION
At Sentinel, we provide solutions that support operators effectively remotely monitor and manage emissions in the subsea environment.
Our systems have been deployed across the entire asset life-cycle, from drilling, producing subsea christmas trees (XT) to final decommissioning.
Our visual indicator enables immediate, field-based characterization and response - eliminating the need for sample retrieval or offsite testing. Uses the same field proven Triggers to characterise emissions at-source and visual displays an alert.
- Identify and characterise subsea emissions at source to avoid delays and escalation
- Reduce testing costs while minimising exposure to hazardous environments
- Easily deployable via ROVs or as a permanent subsea installation
