How the marine voyage calculator works

BP Distance computes the shortest navigable sea route between two ports, accounting for canals (Suez, Panama, Kiel, Corinth), Emission Control Areas (ECA/SECA) and optional piracy-avoidance routing. From the distance and your vessel's speed it derives steaming time and ETA.

Bunker consumption, daily hire and port costs are combined into a single voyage cost estimate, alongside fuel burned and CO₂e emissions for EU MRV / IMO DCS planning. All pricing is centrally maintained, so estimates stay current.

Frequently asked questions

How is the sea distance calculated?

We compute the shortest navigable route between the two ports along real shipping lanes, including transits through canals such as Suez and Panama where they shorten the voyage.

Does it include canal and ECA segments?

Yes. The result splits open-sea and ECA/SECA distance and lists any canals used, so you can model low-sulphur fuel and canal dues accurately.

How accurate is the cost estimate?

Costs use centrally maintained fuel prices, canal tariffs and emission factors. They are planning estimates and should be confirmed against live quotes before fixing.

Is the calculator free to use?

Yes, the public port-to-port distance and cost calculator is free. Signed-in users can additionally save and manage voyages.
