Drewry Reports Global Ship Waiting Times Have Doubled since 2019
Prolonged berth queues reduce vessel productivity, forcing buyers to extend order lead times as carriers manage tight capacity.
Berth Availability
Dock Access
Operational capacity at a maritime terminal represents the frequency and duration with which a designated mooring space is vacant for incoming vessels. Port operators calculate berth availability by dividing the actual time a dock is unoccupied by the total scheduled operational hours. Efficient management of this metric ensures that ships do not remain at anchor waiting for a place to discharge cargo.
Port Congestion
Local weather conditions and labor shift changes frequently alter the real time status of terminal slots. If berth availability drops due to equipment failure or slow stevedoring, the resulting queue increases the turnaround time for every ship in the rotation. Modern port management systems utilize digital twins to simulate vessel arrivals and optimize the window of time each ship spends at the quay.
Global freight markets monitor these figures to estimate the total capacity of a specific trade corridor.
Scheduling Reliability
Ocean carriers monitor these statistics to adjust sailing speeds and reduce fuel consumption when a destination port is full. While high berth availability suggests a lack of congestion, it can also indicate underutilization of expensive waterfront infrastructure. Decisions regarding port expansion often rest on long term trends observed in this specific data point.
