ETA (estimated time of arrival) is the departure time plus sailing time, which is distance divided by speed. Port, terminal and consignee planning is based on this date.
Expert tip: Add a margin to sailing time for weather, currents and canal waiting; updating the ETA when loading is completed and during the voyage prevents planning errors.
