Mermaid Subsea Services (UK) has successfully completed a complex wellhead severance project in the Southern North Sea.
Mermaid Subsea’s Island Valiant vessel
Requiring close coordination across multiple vendors to ensure seamless delivery, the operation was executed safely, on schedule and within budget from the Island Valiant vessel.
Previous efforts to remove the target well were unsuccessful, meaning Mermaid had to use dedicated precision subsea tooling and expert project execution to sever and recover the well conductor, in full compliance with environmental and regulatory standards.
“This successful wellhead severance marks a major achievement for Mermaid,” said Scott Cormack, Regional Director for Mermaid Subsea Services (UK). “By overcoming previous challenges, we’ve demonstrated our capability to deliver complex decommissioning scopes safely, efficiently, and in line with regulations.”
It has been an industrious year to date for Mermaid, which recently announced the safe and successful completion of a scale inhibitor treatment on the Teal P2 well, part of the Anasuria Cluster in the Central North Sea.
Also conducted from the Island Valiant vessel, this time on behalf of Anasuria Operating Company (AOC), the intervention aims to safeguard production flow and well integrity for at least three years.
Recent projects underscore Mermaid’s growing capability in complex subsea work and its strong collaboration with multiple partners.
In addition to plans to introduce Mermaid’s own dive vessel later in 2025, limited availability remains for the Island Valiant, which the company has chartered for a second year.
