01 — DISCHARGE
Still full
The spreader locks four corner castings and lifts the loaded box off the deck. This leg's cargo has arrived; the box has not finished.
02 — DEVAN
The doors open, the cargo leaves
Cargo is unloaded at the freight station, pallet by pallet. The box has not changed; it is simply empty.
03 — DEPOT
Empty boxes stack higher
A box with nothing inside is light, so it can be stacked into higher walls. Here it waits for the next booking.
04 — WASH & REPAIR
Clean, dry and sound before it carries again
Washed, inspected, and any panel that fails is replaced. Clean, dry and sound, it can carry again.
05 — MATCH
A new booking claims an empty box
The system matches the empty box to a new booking and new cargo goes in, pallet by pallet. Empty becomes full again.
06 — RETURN
The return ship waits for the same box
The spreader locks four corner castings again and sets the box into the return ship's stack. The same road, the other way.
THE EMPTY LEG
The other half of the empty box's story
The empty half carries the full half.
