Refining and petrochemicals

Our engineering capability enables us to deliver value and innovation across all phases of the downstream project and operations lifecycle.

From feasibility and concept studies, to FEED, to detailed design and EPC, our capability is comprehensive, and includes considerations as diverse as:

  • Health, safety and environmental optimisation
  • Environmental impact abatement using “best available technology"
  • Process development, process flowsheet optimisation, machinery configuration and driver selection, energy efficiency, plant reliability and availability
  • Plant construction execution and logistics including extensive experience in  modularisation to reduce site activities

We have extensive experience of helping our customers to identify and select appropriate solutions to upgrade their plants in line with current standards and requirements.

Safety and environmental considerations are always paramount, as well as project lifecycle cost reduction, robust plant performance and reliability, and minimal onsite construction, which is advantageous in brownfield facilities.
