Markets
Oil, Gas & Legacy Energy Infrastructure
Brownfield modifications, asset integrity and transition pathways for existing energy assets.
Overview
We provide engineering and advisory support for existing oil and gas assets, with a focus on brownfield modifications, asset integrity, safety and regulatory compliance.
Our work supports operators managing ageing infrastructure while planning for transition pathways.


What we do
How we support this market
- 01Independent engineering review and assurance
- 02Brownfield modification support
- 03Safety and compliance assessments
- 04Interface and contractor management
- 05Integration of low-carbon technologies
Where we add value
Legacy energy assets operate in complex regulatory environments and under tight operational constraints. Our independent, client-side perspective helps owners manage technical risk while maintaining safe and reliable operations.
We bring the same disciplined engineering approach we apply to emerging technology projects into legacy environments, with structured review and risk assessment that improves consistency without replacing engineering judgement.
