Port Waiting
Periods where a ship must wait at anchor because a dock is occupied or a terminal is too congested represent a loss of efficiency for the entire supply chain. These vessel berthing delays occur when the arrival of ships exceeds the capacity of the port to process them. Delays can be caused by labor and equipment plus a surge in trade volume that the infrastructure was not designed to handle.
Operational Cost
Every hour a ship spends waiting is an hour of lost revenue for the carrier and a delay for the cargo owner. In the context of vessel berthing delays, the burning of fuel while at anchor and the disruption to the subsequent schedule of the ship add costs. These events force carriers to either speed up on the next leg of the journey, which uses more fuel, or skip ports to get back on schedule.
Shippers often face additional charges as terminals pass on the cost of managing the congestion. Accurate data on these wait times is a requirement for logistics planners who must decide which ports to use and how much lead time to build into their delivery estimates.
Consistent Congestion
Regular waiting times at a specific port indicate that the local infrastructure or labor force is not keeping pace with the demands of trade. Prolonged vessel berthing delays can drive shipping lines to find alternative terminals that offer more reliable service.
