Laem Chabang Port Phase 3, Thailand

Laem Chabang Port Phase 3 demonstrates how large-scale terminal planning can optimize cargo flows while supporting higher capacity, modal shift and greener port operations. The expansion is being developed by the Port Authority of Thailand as part of the Eastern Economic Corridor program. It is designed to increase Laem Chabang’s overall container handling capacity from approximately 11 million TEU to 18 million TEU per year, while improving the physical integration of marine terminals, road access, rail transport and automated container handling systems.

Phase 3 covers a major new port area incorporating Container Terminals E and F, associated back-of-terminal facilities, roads, utilities and rail infrastructure. Terminal F comprises F1 and F2, each planned for approximately 2 million TEU per year. The broader development also includes new double-track railway infrastructure, expanded internal and external transport connections and improvements intended to address congestion within and around the port.

EECO states a target to increase rail freight to 6 million containers a year, raising rail's share from 7% to 30% (EECO, n.d.). Containers and TEU are different units: 30% of 18 million TEU would be 5.4 million TEU, so the two figures should not be read as equivalent. The design therefore treats rail access as an integral part of terminal capacity rather than as a peripheral hinterland facility. A Single Rail Transfer Operator facility and associated track infrastructure are intended to consolidate rail-container handling and improve transfers between the quayside, storage yards and national rail network.

The project also incorporates automated container management and cargo handling systems. The Phase 3 Part 4 package includes 2 port cranes, 6 semi-automatic electric rubber-tired gantry cranes and 2 rail-mounted gantry cranes, with IT systems (Government of Thailand, 2023). This is one package, not the complete terminal fleet. This allows the physical terminal layout to be coordinated with equipment deployment and digital control rather than optimizing each element separately.

The optimized configuration is intended to accommodate substantially higher cargo volumes while reducing road dependency and congestion. Increasing rail modal share can reduce truck movements associated with hinterland container transport, while electric and automated equipment can reduce terminal energy consumption and local emissions. The Eastern Economic Corridor Office explicitly links the project to development of Laem Chabang as a Green Port, alongside automation and lower national logistics costs.

From a Green Port engineering perspective, Laem Chabang Phase 3 illustrates how terminal layout optimization extends beyond arranging yard blocks. The project integrates berth capacity, yard operations, rail-transfer facilities, road networks, automated equipment and hinterland connectivity into one cargo-flow concept. This is intended to allow additional throughput to be accommodated with fewer transport conflicts and a greater share of freight moved by lower-carbon modes.
