Port Congestion Not Tied to Terminal Investment Gaps: Drewry

Drewry, a leading maritime research and consulting firm, has released analysis suggesting that port congestion is not primarily attributable to insufficient capital investment in terminal infrastructure. This finding challenges a prevalent narrative in supply chain circles that blames port delays on underinvestment in container handling facilities and berth capacity. The research implies that congestion stems from operational and demand-side factors rather than physical infrastructure constraints—a significant distinction for port operators, shipping lines, and shippers seeking to address service reliability issues.

For supply chain professionals, this insight reshapes how organizations should approach port congestion mitigation strategies. Rather than advocating solely for terminal expansion projects, companies should examine labor availability, truck dwell times, vessel scheduling efficiency, and seasonal demand surges as primary levers for reducing delays. Ports that have invested heavily in terminal capacity yet still experience congestion may be facing resource allocation challenges or operational bottlenecks that technology and process improvements could address more cost-effectively than new infrastructure.

The implications extend to sourcing and logistics strategy. If congestion is operationally driven rather than capacity-driven, supply chain teams have greater agency in managing risk through better port selection, strategic timing of shipments, and demand-supply coordination with warehouse and distribution partners. Organizations should recalibrate their resilience planning to focus on operational flexibility and visibility rather than assuming new terminal capacity alone will solve congestion problems.
