All projects on this site are fictional and labelled as demonstration projects. They show how we reason about a move, not results we claim.
118 t transformer, factory to substation
A worked example of a multimodal move. Company, client, locations and figures are fictional.
The load
| Cargo | Power transformer, oil drained, 1 piece |
|---|---|
| Dimensions (L×W×H) | 9.2 × 3.6 × 4.1 m |
| Weight | 118 t |
| Lifting points | 4 lifting lugs, spreader beam required |
| Window | Delivery within a 5-day installation window |
Why not road all the way
On a modular trailer the transport height would be well above 5 m. Along the full road route that meant several bridges to avoid and a long detour over weight-restricted structures. Both the factory region and the substation region have a quay within a short road distance, so the long leg moves to the water.
Constraints we planned around
- Bridge air draught on the barge leg at high water
- Bearing capacity of Quay B for SPMT roll-off
- Night-time road legs to limit traffic impact
- Crane on site booked for one day only
Planning sequence
- Week 1–2
Cargo data check, lift plan for both quays, quay bearing capacity confirmed.
- Week 2–4
Route surveys for both road legs, swept path at the substation entrance, permit applications.
- Week 5
Barge booked against the water level forecast, stowage and sea-fastening plan approved.
- Week 6
Move: road leg at night, lift-on, barge leg, Ro-Ro at Quay B, on-carriage into the window.
Press line relocation, 14 pieces
A fictional plant relocation: dismantling sequence agreed with the machine builder, 14 pieces split over low loaders and two modular combinations, and an indoor gantry lift where no crane could reach. The heaviest piece went by exceptional road transport with escort.

Process modules to an inland site
A fictional series of four process modules, each over 6 m wide. Delivered by inland vessel to a quay near the site and rolled off with SPMTs, leaving a road leg of a few kilometres instead of a long permit route.
