Sentinel Subsea has announced the successful completion of a major six-figure project in the North Sea, deploying two WellSentinel Coral systems for a key operator.
This milestone supports a large-scale drilling operation and marks a significant step forward in the company’s mission to enhance offshore safety and operational efficiency.
The WellSentinel Coral systems were installed in February 2025, monitoring the integrity of the wells throughout the suspension period and ensuring safe, efficient operations during this critical phase.
Notably, this project represents the first time WellSentinel technology has been implemented at the start of a well’s lifecycle, highlighting the value of passive monitoring in multiple offshore operations.
By adopting this innovative approach, the operator is adhering to the As Low As Reasonably Practicable (ALARP) principle, minimising risks associated with future operational scheduling while awaiting the installation of the christmas trees (XT).
The Coral systems were installed from the jack up onto 18 ¾” wellheads via crane wire through the texas deck, with preconfigured detection capabilities streamlining the process and eliminating the need for in-well intervention.
Neil Gordon, CEO of Sentinel Subsea, commented: “We are thrilled to have successfully completed this project, which highlights Sentinel Subsea’s commitment to safety, innovation, and growth.
“This is a key moment for us, as it is the first time our WellSentinel technology has been deployed at the beginning of a well’s lifecycle.
“Partnering with a major operator in the North Sea strengthens our presence in the region and contributes to our continued global expansion.”
Founded in 2018 and headquartered in Aberdeen, Sentinel Subsea has established a strong track record, deploying WellSentinel passive monitoring solutions for both major and independent operators worldwide.
This latest project further cements the company’s leadership in subsea monitoring technologies and its dedication to advancing offshore operational safety.
