Sentinel Subsea Ltd.

Specialising in the passive monitoring of subsea infrastructure and equipment, Sentinel Subsea’s low cost and easy to deploy technology continuously monitors the integrity of subsea oil and gas assets and carbon capture sites, significantly lowering risk, reducing inspection, repair and maintenance (IRM) costs and protecting the environment. Cost efficient environmental stewardship is the foundation of a thriving, 21st century energy industry. Sentinel Subsea holds the key. Our transformative technology, WellSentinel™, detects and alerts in the case of a loss of containment, de-risking wells and helping operators: Lower subsea asset risk: Asset owners who deploy our continuous passive monitoring systems have a constant and reliable picture of a subsea assets integrity status. Should there be any unwanted loss of containment; the systems provide an early alert, allowing the situation to be dealt with immediately. Reduce IRM, reduce costs: By lowering an assets risk profile and providing optimum subsea inspection, our technologies reduce the need for repeated asset IRM, reducing OPEX across subsea operations. Our low-cost solutions also de-risk extending the window for subsea intervention or decommissioning activities and can help assist asset life-extension. Protect the environment: By being able to rapidly respond to a subsea integrity incident means an asset owner can mitigate any environmental consequences. Our in-situ systems demonstrate strong environmental stewardship and reduce carbon emissions created by manual inspection methods. Our system is: Passive: The systems provide passive monitoring by gathering and physically detecting specific gas and/or fluid material in the subsea marine environment. Long term: With a 25-year deployment lifecycle, our technologies are robust and designed to survive in harsh subsea environments. Simple to deploy: Easily integrated with existing integrity management systems, designed for easy and quick deployment.
