Pre-commissioning & Commissioning
Systematic start-up — from flushing and loop checks to stable operation at design capacity.
Pre-commissioning & Commissioning at Specx
A plant is only finished when it runs as designed. Our commissioning engineers prepare system-by-system procedures, carry out flushing, leak tests, loop checks and functional tests, then lead start-up, stabilisation and the performance test run.
We train the owner's operators alongside the equipment and stay through the first operating period to make sure the handover holds.

Questions about pre-commissioning & commissioning
Can Specx deliver pre-commissioning & commissioning as a standalone service?
Yes. Pre-commissioning & Commissioning can be engaged on its own, or combined with our other engineering services into a single EPC or turnkey contract.
What information do you need to quote for pre-commissioning & commissioning?
Typically the process description or licensor data, capacity, site location, applicable codes and standards, and the expected schedule. Our engineers will help define anything that is not yet fixed.
