It's how we describe our approach to commissioning, not a separate service. Once construction is complete, the sooner the plant is online, the sooner production and revenue start. We focus on taking the control system off the critical path: we test it before site, commission it in step with the other disciplines and support your operators through ramp-up.

Dry commissioning tests the control system without process material. It covers loop checks, instrument and drive setup, cabinet testing, and interlock and permissive testing. Wet commissioning runs the plant on water, so we can test sequences, validate and tune control loops, and balance the plant before ore is introduced.

Virtual commissioning tests control logic against a simulated model of the process before it reaches site. Faults in sequences, interlocks and control strategies show up in the simulation, where they're quicker and cheaper to fix than on a live plant. The same approach can be used to train operators before start-up.

Some of it can. Logic transfer, project updates and parts of testing can be done over secure remote access, with engineers on site for work that needs hands on the system. Most projects use a mix.

Yes. Our engineers coordinate with operations, process, electrical and mechanical disciplines as your commissioning manager directs, and engage equipment vendors for package integration testing and verification.

Yes. At Quellaveco, our team supported start-up on a plant-wide control system configured by another contractor, which meant first getting to know its customised library.

After the base control layer is stable. APC relies on well-tuned regulatory control, so during commissioning and ramp-up we focus on stable loops, then look at APC once the plant is running consistently.

We provide input to commissioning dossiers and close-out documentation, and transfer knowledge to your engineers. For ongoing help, our Operations Support team offers remote, 24/7 and onsite support.
