Just-in-Time (JIT) Arrival

Just-in-Time arrival is the practice of timing a ship’s arrival to match berth and pilot availability, so the vessel slow-steams the final leg rather than rushing to anchor and wait. Cutting the speed that would otherwise be burned in a queue saves fuel and CO2 with no loss of port throughput, which makes JIT an operational decarbonization lever. It depends on reliable berth-availability data exchanged ahead of arrival, the gap the DCSA and IMO Port Call Optimization data standards address.
