HMM Invests in Tacoma Terminal Upgrade to Boost Capacity by Nearly 50 Per Cent

## HMM Drives Major Capacity Expansion at Tacoma's Washington United Terminals South Korean container carrier HMM is making a significant capital investment in Washington United Terminals (WUT) at the Port of Tacoma, with the upgrade expected to lift the terminal's cargo-handling capacity by nearly 50 per cent, according to Port Technology. The project forms part of a broader strategic push to future-proof the Northwest Seaport Alliance (NWSA) gateway — one of the busiest container port complexes on the US West Coast — enabling it to service the next generation of ultra-large container vessels (ULCVs) that are increasingly dominating transpacific trade lanes. ### Strategic Significance for the Northwest Seaport Alliance The Northwest Seaport Alliance, which jointly operates the marine cargo facilities of the ports of Seattle and Tacoma, has been actively working to strengthen its competitive position against rival West Coast gateways, including the ports of Los Angeles and Long Beach. A near-50 per cent capacity increase at WUT represents one of the most substantial single-terminal expansions the NWSA has seen in recent years. For HMM, the investment underscores the carrier's commitment to its transpacific network and its confidence in the Pacific Northwest as a key gateway for US-bound cargo. The upgrade is expected to improve vessel turnaround times, increase throughput efficiency, and reduce congestion — factors that have become critical considerations for shippers and carriers alike following the supply chain disruptions of recent years. ### Industry Context The move reflects a wider industry trend of ocean carriers taking a more direct role in terminal infrastructure investment, seeking greater operational control and capacity assurance as vessel sizes continue to grow. Carriers deploying vessels in the 20,000+ TEU class require terminals with deeper berths, higher-capacity cranes, and expanded yard operations — all elements likely addressed in the WUT upgrade. The investment also signals continued confidence in US West Coast port infrastructure at a time when trade routing and port competitiveness remain closely watched by logistics professionals and cargo owners. Further details on the timeline and specific infrastructure components of the WUT upgrade are expected to be released by the NWSA and HMM in the coming months.
