Proof Points Multi-Unit FAT Must Produce
- Identity and configuration — serials, nameplates, frequency, voltage, and controls versions for every unit in the lot.
Performance evidence — load-bank or factory test records consistent with the stated duty; .
- Paralleling readiness — where the buy is a plant, sync and load-share philosophy documented — see multi-unit paralleling.
- Documentation chain — ownership, service history, and spare lists that match commonality policy.
- Punch-list discipline — open items tracked to closure before title and shipment, not after containers sail.
FAT Versus Yard Acceptance Versus Site Commissioning
Factory acceptance wins when units are new or refurbished under controlled conditions and the buyer needs early evidence before freight risk accumulates. It does not replace site proving under real BOP and ambient conditions.
Yard / staging acceptance wins for surplus and multi-source lots where preservation, re-test, and lot matching happen before mobilisation — pair with staging yards readiness.
Site commissioning wins as the final proof under Extreme Ownership with EPC/EPCM accountability. Skipping earlier gates makes site days into expensive archaeology.
How Buyers Should Sequence Acceptance Diligence
- NDA and project qualification — MW, frequency, fuel, sites, proof of funds.
- Inventory shortlist from https://www.uspeglobal.com/inventory/.
- Acceptance plan defining FAT, yard, and site witness points per unit and per paralleling block.
- Inspection participation — USD 20,000 fee, refundable if not as represented; 50 percent credited if the buyer proceeds.
- Term sheet and execution under FCPA/OFAC; optional O&M attachment via operations and maintenance.
Lot-Level Artefacts That Survive Freight
Acceptance packs should travel with the lot: test sheets, photos of nameplates, configuration baselines, spare manifests, and open-item closures. Warranty assignment language should be drafted in parallel — see warranty assignment on wholesale lots — so buyers do not discover orphan coverage after COD.
For data-centre and critical-load programmes, align acceptance with continuity drills and data centre themes. Optional dual-fuel and turbine growth paths: dual-fuel generators · natural gas turbines.
Witness Points Buyers Should Not Skip
Engineering ownership for BOP interfaces sits with power plant engineering and EPC, not with a photo album. When EPC contractors buy wholesale lots for clients, keep acceptance exhibits transferable — see wholesale diesel for EPC contractors.

Common questions
Is FAT enough without site commissioning?
No. FAT reduces freight and configuration risk; site commissioning under real BOP remains the final plant proof.
Do surplus lots use the same gates?
Gates adapt — yard and re-test often carry more weight — but documentation, inspection rights, and punch-list closure still apply.
Why owners choose USP&E
USP&E is a full-service engineering, EPC and O&M company, not a broker. One team designs, builds and runs your plant, so nothing falls between contracts.
