Delivering safe, efficient, and technology-enabled lifecycle support for offshore energy assets.
James Fisher provides end-to-end commissioning and decommissioning solutions that help offshore operators bring assets online safely — and retire them responsibly.

Topside
We provide above-water commissioning and decommissioning services, supporting both oil & gas and offshore wind projects with a solutions-led approach.
From early-stage commissioning through to full operational readiness, we ensure assets are safely brought online, fully tested, and optimised for performance.
In decommissioning, we deliver safe, compliant, and efficient asset retirement, supporting complex offshore operations while minimising environmental impact. We also enable critical environmental protection and monitoring activities, ensuring projects meet evolving regulatory requirements.
We provide solutions to support with -
- Blade inspection, repair & maintenance
- Control room & OMS services
- Air compressors for big bubble curtain projects
- Well testing equipment and services

Subsea
Our subsea commissioning and decommissioning services ensure systems are fully operational, resilient, and ready for long-term performance.
We provide safe and efficient subsea asset removal, ensuring full compliance while reducing environmental impact. Through advanced excavation, intervention, and remotely operated technologies, we maintain precision and control throughout every phase.
By focusing on subsea integrity, operational continuity, and lifecycle optimisation, we help operators reduce downtime, manage risk, and deliver reliable outcomes beneath the surface.

Digital solutions
We enhance commissioning and decommissioning services through advanced digital solutions, enabling smarter, faster, and more efficient project delivery.
Our digital approach brings greater accuracy, visibility, and control to every stage. Through intelligent inspection planning and real-time reporting, we help operators streamline workflows, reduce manual processes, and improve decision-making.
By digitising critical commissioning and decommissioning activities, we enable better asset intelligence, earlier issue detection, and more efficient intervention strategies. This results in reduced downtime, improved compliance, and optimised performance across both new and ageing infrastructure.
Focused on data-driven insight, operational efficiency, and continuous innovation, we help our customers unlock greater value from their assets, delivering smarter outcomes today while preparing for the future of energy operations.
