Port Equipment Buyers Who Skip the FAT Pay for It Twice
Quote from chief_editor on April 3, 2026, 11:34 amPort operators routinely waive factory acceptance testing on Chinese crane and bulk handling equipment. The cost of that decision appears at commissioning, not at delivery.
A West African port operator took delivery of two ship-to-shore cranes from a Zhoushan manufacturer in 2022. The cranes had been manufactured on schedule, shipped on schedule, and installed by the manufacturer's commissioning team on schedule. The operator had waived the factory acceptance test on the basis that a previous order — four smaller rubber-tyred gantry cranes from the same facility — had been delivered without issues, and the FAT travel cost and associated delays were not in the project budget.
Commissioning took 34 days instead of the planned 14. The primary issues: the trolley drive control logic had a software parameter that caused hunting behavior under load in crosswind conditions above 12 m/s, a specific condition that does not occur during factory testing because the factory test facility is indoors. The secondary issue: three of the eight main hoist rope sheaves had been installed with the wrong groove profile for the rope diameter specified, detectable only under load. The tertiary issue: the anti-collision system radar units had been calibrated to a different port layout than the actual installation.
None of these were manufactuing defects in the traditional sense. All of them were configuration and commissioning issues that would have been caught — and corrected in the factory, at the manufacturer's cost — during a properly executed FAT.
The FAT Exists Precisely Because Commissioning Is Expensive
The logic buyers use to skip factory acceptance testing almost always reduces to: we have bought from this supplier before, and the cost and time of the FAT is significant. Both of those inputs can be true and the conclusion can still be wrong.
Factory acceptance testing for port cranes and bulk handling equipment does two things. First, it identifies configuration issues before the equipment leaves the controlled environment where corrections are cheapest. Second, it creates a contractual baseline: the buyer has seen the machine perform to specification, and subsequent deviations are unambiguously the supplier's problem. Without an FAT, every commissioning dispute becomes a negotiation about whether the issue pre-existed delivery or occurred during installation — a negotiation that takes place on the buyer's site, on the buyer's time, with the supplier's commissioning team already on-site and already billing.
Zhoushan, Nantong, and Shanghai are where the majority of large Chinese port equipment is built. The commissioning teams that come with the equipment are skilled at the equipment in a factory environment. They are less familiar with the specific conditions of your port — wind, tide, berth geometry, existing systems, operator interface preferences. An FAT would have surfaced the crosswind control issue by simulating the load profile. Instead, the commissioning team spent 34 days discovering the port's operating envelope empirically.
The Budget That Skipped the FAT Paid for 20 Extra Days
The 20 additional commissioning days cost the West African operator $1.8 million in delayed port throughput during what was the pre-harvest export season for the country's primary agricultural exports. The FAT that was not conducted would have cost approximately $180,000 in travel, accommodation, and schedule impact — and would have taken 5 days at the factory.
The more persistent cost is in the software parameter. The manufacturer corrected the control logic during commissioning. Correcting it required a firmware update from the drive manufacturer's engineer, who had to fly from Shenzhen. The update was not part of the commissioning team's original scope. The delay and the flights were billed to the project as a variation. The operator paid for it.
Waiving a factory acceptance test is not a budget decision. It is a decision to move the problem-finding phase from the factory to the port, where finding problems costs more by a factor of ten.
