Our service offering 

We embed our expertise throughout the project lifecycle, from FEED and Detail Engineering through to Fabrication, fit-out, final commissioning and start-up. Our experienced commissioning and completions team integrate seamlessly into your project team, bringing proven processes and industry best practice to every stage.

  • Commissioning & completions planning – Early engagement during FEED to shape strategy, sequencing, and resources
  • Systems completions management – Defining system boundaries, tagging, and certification
  • Manpower & leadership – Supplying specialist commissioning teams to manage execution on your behalf
  • CMS database expertise – Working with your preferred completions management system or implementing and configuring leading off-the-shelf CMS solutions
  • Project execution & handover – Managing completions through mechanical completion, pre-commissioning, commissioning, and performance testing, ensuring smooth transition to operations

Flexible CMS solutions 

Continuity in completions and commissioning is critical to achieving a safe, efficient, and predictable start-up. We recognise that many operators and EPCs have established standards and preferred completions management databases in place. We can integrate directly into these systems to maintain consistency across projects, assets, and operating regions.

Where no system is mandated, we can provide a complete solution by supplying, configuring, engineering, and implementing a range of proven CMS platforms. This ensures you benefit from a structured, transparent, and traceable approach to completions, while retaining the flexibility to align with project-specific or corporate requirements.

Whether we are working within your existing CMS framework or delivering a turnkey system, our focus remains the same: a continuous, standardised approach to completions and commissioning that reduces risk, improves handover quality, and drives first-time-right project delivery.
