JIT arrival

JIT arrival (just-in-time arrival) is a port-call-optimization practice where a ship adjusts speed on passage to reach the pilot boarding point only when the berth, tugs, and resources are ready, instead of steaming at full speed then waiting at anchor. By converting idle anchorage waiting into slower steaming, it cuts fuel burn and GHG emissions on the cubic speed-power relationship, which is why the IMO promotes it. The Just In Time Arrival Guide was published in 2020 by the Low Carbon GIA under the GloMEEP and GreenVoyage2050 framework, supporting MEPC.323(74) on ship-port data exchange. JIT depends on early, trusted sharing of the requested-time-of-arrival between port, agent, and ship, which standards from DCSA and the Port Call Optimization taskforce address.
