Ship loaders, train load-out bins, weightometers, sampling stations
Commissioning software for load-out where a mis-calibrated weightometer turns into a contractual dispute at the wharf.
The load-out chain — train load-out bins, rail loop infrastructure, ship loaders, wharf conveyors, weightometers and automated sampling stations — is where a mine's product finally becomes a shipped, invoiced tonne, and every custody-transfer measurement has to be proven before the first vessel or train is loaded. Deskely tags each load-out asset and measurement point individually, so calibration, functional testing and commercial sign-off are evidenced the way the offtake agreement actually requires.

The problem
The load-out circuit is the last place an uncalibrated instrument can hide before it becomes a shipping dispute.
Train load-out bins, rail loop points and signalling interfaces, wharf conveyors, travelling ship loaders and automated sampling stations are commissioned by rail, port authority and OEM specialists who rarely share a single register with the mine's own commissioning team.
Every weightometer, belt scale and sampling head in that chain is a custody-transfer instrument: if it is not calibrated and functionally proven before first load-out, the dispute shows up later as a reconciliation argument with the offtaker rather than a fixable snag on site.
Deskely tags every load-out asset — bin gates, rail loop signals, ship loader slew/luff/travel drives, weightometers and sampling stations — individually, so calibration certificates and functional test records are attached to the exact instrument the commercial contract references.
Setting up the register
Load-out bins, rail interfaces and shiploading equipment are structured to match the custody-transfer chain.
Train load-out bins are tagged with their gates, dust extraction, load cells and rail loop signalling interface, while wharf conveyors, ship loaders and their slew, luff and travel drives sit as their own subsystem downstream.
Weightometers, belt scales and automated sampling stations are held as their own measurement-point tags, cross-referenced to the offtake agreement's specified custody-transfer points rather than buried inside a generic conveyor checklist.
Rail interface drawings, ship loader OEM manuals and metrology certificates are parsed into that structure, so the register mirrors the actual chain of measurement responsibility from mine gate to vessel hold.
Execution
Calibration, functional testing and trial loading run instrument by instrument before commercial sign-off.
Weightometer and belt scale calibration is captured against NATA or equivalent accredited procedures, with tolerance results logged at the instrument tag so any drift is visible before it reaches a shipping statement.
Ship loader functional testing — slew, luff, travel, boom conveyor tripping and dust suppression — and train load-out bin gate sequencing are captured on tablet at the wharf and rail siding, with rail signalling interlocks tested jointly with the rail operator's own commissioning team.
Trial loading runs against a nominated tonnage are logged with weightometer readings reconciled to survey or draft-mark figures, giving a documented basis for accepting the measurement chain before it is used commercially.
Commercial readiness and handover
Load-out is released for commercial operation only once every custody-transfer instrument has a signed calibration record.
Mechanical completion for the load-out chain is issued per asset — bin, loop, loader, weightometer, sampler — with commercial load-out readiness held as a separate gate that requires every custody-transfer instrument's calibration certificate to be signed and current.
Interface sign-off with the rail operator and port authority is captured against the same register, so shared infrastructure like the rail loop and berth is not certified by the mine's team alone without the counterpart's evidence attached.
The handover pack for the marketing and logistics team includes weightometer calibration history, sampling station verification and rail interface test records, giving them a documented basis to start invoicing shipments from day one.
Loading rate guarantee and demurrage exposure
A ship loader that runs at rated tonnes per hour on paper still exposes the mine to demurrage if the guaranteed loading rate was never proven under a realistic trial.
Offtake and charter party agreements typically specify a guaranteed loading rate in tonnes per hour, and if the actual sustained rate falls short once a vessel is alongside, the mine carries the demurrage cost — yet the ship loader's rated capacity is often proven only against a clean, dry, well-sized product sample rather than the moisture content and fines proportion the mine will actually be loading in its first commercial season.
A stockyard reclaim rate that cannot feed the loader fast enough, a belt scale that has drifted since its last calibration, or a boom conveyor that trips on a moisture-affected parcel all show up the same way commercially: the vessel sails late and the demurrage invoice lands on the marketing desk with no commissioning record to contest it against.
Deskely records the loading rate trial against the actual reclaim and stockyard conditions on the day, including moisture content and product size distribution, alongside the weightometer calibration current at the time, so a demurrage dispute can be answered with the commissioning evidence the loading rate guarantee was actually tested against, not a generic rated-capacity certificate from the OEM.
How it runs
From bin gate to bill of lading.
Load-out commissioning is really custody-transfer commissioning, and every instrument in the chain needs its own calibration record before the first shipment is invoiced against it.
- 01
Tag the custody-transfer chain
Load-out bins, rail interfaces, ship loaders, weightometers and sampling stations registered as individual measurement-point assets.

Calibrate before functional testing
Weightometer and sampler calibration captured against accredited procedures at the instrument tag.
- 03
Functionally test and trial-load
Ship loader and load-out bin functional testing, rail interlock testing and a nominated trial loading run recorded against the chain.
- 04
Release for commercial operation
Load-out readiness gated on every custody-transfer instrument holding a signed, current calibration certificate.
