Commissioning, FAT & SAT

Commissioning proves the plant does what it was designed to do. From Factory Acceptance Testing before despatch to wet commissioning and performance proving on site, each gate is documented and signed off before the next.

Commissioning, FAT and SAT in Detail

FAT — before it ships

At our works or the OEM's, the assembled skid and its controls are function-tested so faults are found before they reach site.

  • Mechanical and control function testing
  • I/O and interlock verification
  • Punch-list cleared before despatch
  • Witnessed sign-off where required

SAT & wet commissioning

On site, the plant is energised, filled and run on real flow — loops tuned, set-points confirmed and performance measured against the design.

  • Cold then wet commissioning on live flow
  • Control-loop tuning and alarm verification
  • Performance proving against design targets
  • Commissioning records and snag close-out

Standards & Deliverables

FAT SAT Wet commissioning Loop tuning Performance test Punch-list

Commissioning ends with a plant proven to its performance guarantee and a documented test record — the evidence base that supports handover, training and the maintenance contract.

Other Installation Phases

Planning an installation?

Reynolds & Bauhm delivers installation as a single coordinated scope — survey, erection, pipework, E&I, commissioning and handover — with one accountable team from delivery to performance sign-off.

FAT & SAT: Proving It Before and After Delivery

We prove plant twice — once in the factory and again on site — so problems are caught where they are cheapest to fix. Factory acceptance testing (FAT) exercises the skid or system on our floor: control logic, alarms, interlocks and, where possible, wet performance are demonstrated to the client before dispatch. Site acceptance testing (SAT) then repeats the key checks once the plant is installed and connected, confirming it performs in its real setting under real services. Both are run to agreed test scripts with documented results. This FAT/SAT discipline turns commissioning from a hopeful start-up into a verifiable, signed-off demonstration that the plant does what was specified.
