THREE60 Energy, Innovair & Oil States Announce Strategic Alliance for Caisson Integrity Management

Aberdeen – 17^th of February 2026 – THREE60 Energy, Innovair, and Oil States are pleased to announce a strategic alliance to deliver integrated solutions for caisson integrity management in the global oil and gas sector. The collaboration combines proven inspection, engineering, and repair expertise to provide a seamless, end-to-end service that enhances safety, assures compliance, optimises operational efficiency and reduces lifecycle cost and complexity for operators.

Managing caisson integrity is a significant challenge for operators of ageing offshore oil and gas assets, as it presents both safety and operational risks and involves complex assessment and repair processes. The alliance builds on THREE60 Energy’s Engineering, Procurement, Construction & Commissioning (EPCC) capabilities, Innovair’s advanced inspection technologies, and Oil States’ field experience in repair and installation. Together the team provides a unified workflow from development and delivery of inspection programmes, engineering and implementation of remedial scopes. Each company contributes a distinct specialist capability, giving operators access to a comprehensive, integrated managed service delivered through a single point of accountability, providing a more streamlined and efficient service to clients. With proven capability across mature basins such as the North Sea and an extensive international footprint, the alliance can deliver integrated caisson solutions globally.

Innovair brings high-precision scanning, sensing, and robotics solutions to intelligently deliver reliable inspection data. THREE60 Energy translates these insights into engineering solutions and oversees project delivery, while Oil States offers proprietary products ensuring repairs, refurbishment, and replacements are carried out safely and efficiently.

The three companies have already demonstrated the value of this model through an ongoing integrated inspection-to-repair project for a global operator in the North Sea, which formed the basis for the alliance. The offering is available as a standalone caisson integrity service or as part of an integrated EPCC solution, reflecting commitment to flexible and responsive support across the asset lifecycle.

Alasdair Smith, Managing Director of EPCC at THREE60 Energy, said, “This alliance brings together the best of three companies, combining Innovair’s technology, Oil States’ proven operational expertise, and THREE60 Energy’s engineering and project delivery capability. Together, we offer clients a comprehensive solution for managing caisson integrity safely, efficiently, and cost-effectively.”

Stuart Lawson, Solutions Director of Innovair, said, “By integrating our inspection technology with engineering and operational expertise of THREE60 Energy and Oil States, we are redefining the way caisson integrity can be managed across the industry.”

Garry Stephen, Group Vice President, UK and Asia of Oil States, said, “This alliance builds on our experience in repair and installation services and provides clients with a trusted, end-to-end solution. By working closely with Innovair and THREE60 Energy, we can ensure safe and efficient maintenance and upgrades for caissons worldwide.”
