Frequently Asked Questions

What does your plant commissioning and start-up service include?

Our commissioning and start-up service is a systematic process to transition your plant from construction to operation safely and efficiently. It includes pre-commissioning checks, system integrity verification, the safe introduction of chemicals, and final performance testing. We also provide hands-on training for your operations team.
Our PEP is the complete blueprint for your plant. It includes process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), material and energy balances, equipment specifications, control philosophy, and safety system designs. It provides all the technical information required for detailed engineering and construction.
We design and implement advanced instrumentation and control systems as the central nervous system of the plant.
