What container mission swapping is — and why it cuts empty miles

The empty-mile problem

Every day, container trucks run empty. A carrier drops a full box at a terminal, then drives back with nothing — or repositions an empty container across town to a depot that already has a surplus. Those empty kilometres burn fuel, driver hours and road tolls while earning zero revenue.

What swapping changes

Container mission swapping lets two carriers trade legs of work in real time. If Carrier A has an empty headed north and Carrier B needs that exact equipment up north, they swap the mission instead of each running a one-way empty. The container moves once; both trucks stay loaded.

PortChief is the marketplace that makes the match. Carriers post the missions and empties they want to hand off, and the platform surfaces the nearest compatible counterpart — by location, container type and time window.

Why it matters

Cutting empty miles is the single biggest lever a drayage carrier has on cost. Less empty running means lower fuel spend, fewer terminal trips, better driver utilisation and a smaller carbon footprint per loaded move. Swapping turns a structural inefficiency into shared upside.
