Our Mission

Global leadership in monitoring hydrocarbon well integrity for environmental peace of mind.

About us

Sentinel Subsea has developed a unique, Patent Applied For, passive method for the long-term environmental monitoring of suspended and abandoned (decommissioned) subsea oil and gas wells.

This solution introduces a low-cost, risk-free means of obtaining an early alert in the event that a well loses its integrity and starts leaking into the subsea environment.

In addition to the obvious environmental benefits this brings, it reduces costs by allowing operators to only inspect wells when there is an indication that this is needed, and will contribute to the OGA's objective of reducing decommissioning costs by 35% through the monitoring and validation of new P&A technologies and processes.

The Sentinel Subsea team



Sentinel Subsea is delighted to be a member of the Scottish Enterprise High Growth Ventures portfolio of companies.

The company was created as a direct consequence of the Scottish Enterprise backed initiative called Grey Matters (delivered by Elevator UK).

The Sentinel team is grateful for the funding it received from OGIC to engage Heriot Watt University to conduct validation research.

Our Core Values


If it isn't right, we don't do it.


We reject "that's the way it's always been done" thinking and take a fresh, holistic, approach to solving problems.


If we agree to do something we will give our best endeavours to make it happen in a timely manner.


We know that we do not have all the answers. If we are wrong, we'll admit it. If we don't know the answer, we'll say so.



Our team of highly experienced professionals

Between us, we have almost 100 years of experience, multi-billion dollar responsibility, a long track record of commercialising new technologies and over 40 patents granted or pending.

As Chief Executive of Sentinel Subsea, Neil brings an impressive track record within the oil and energy sector. Over 34 years in well construction have seen Neil play an integral role within a number of global companies, including Weatherford, BJ Services and Frank’s International. His expertise has been gained via a broad range of operations, sales, senior management and board level activity. During this period Neil managed global product line portfolios with combined annual revenues of over $3B while also successfully championing and launching a number of new and innovative well construction technologies.

Sentinel Subsea is the result of an idea which Neil considered a number of years ago. Taking part in the Grey Matters programme run by Elevator UK for Scottish Enterprise helped Neil bring the idea to fruition, and, with Andrew and Elliot, Neil is now working hard to help the oil and gas industry demonstrate good environmental stewardship throughout the decommissioning process and beyond.
