Laem Chabang Port plans Phase 4 expansion as cargo volumes exceed capacity, driven by AI investment and advanced manufacturing growth.
Driven by the global surge in artificial intelligence investment and a sharp rise in advanced manufacturing activity, Laem Chabang Port - Thailand's principal deep-water gateway - is approaching the limits of its operational capacity, prompting authorities to advance plans for a further expansion phase.
Thailand Port Authority Chairman Decha, speaking recently to Bloomberg, confirmed that cargo volumes at Laem Chabang now exceed the port's designed throughput ceiling, with the authority receiving complaints regarding port congestion and shipment delays. In anticipation of projected cargo growth over the coming years, the Port Authority has determined that additional infrastructure planning is necessary. Located approximately 120 kilometres southeast of Bangkok in Chonburi Province, Laem Chabang Port serves as the central logistics hub of Thailand's Eastern Economic Corridor and handles the overwhelming majority of the country's seaborne import and export trade.
Decha disclosed that the Port Authority is currently evaluating the launch of a Phase Four expansion programme, designed to build upon the capacity gains delivered by the ongoing Phase Three works. Authorities are assessing the port's potential future scale, the total investment required, and a concrete implementation timeline. The fact that Phase Four planning has commenced before Phase Three construction is complete reflects the urgency with which port capacity must be developed to keep pace with accelerating cargo demand.
Laem Chabang operates under a phased development model, with select terminal facilities managed by private operators. The concession agreements covering Phase One and Phase Two expired several years ago, and incumbent operators - including Hutchison Ports - have been permitted to continue managing the relevant facilities on an interim basis. The Port Authority intends to relaunch a competitive tender process to identify new operators for these terminals. Any transition in operational management carries implications for subsequent terminal handling arrangements, service standards, and shipper relationships.
Phase Three of the Laem Chabang expansion is being advanced by a joint venture between Thai energy major Gulf Development and PTT, the state-owned national oil company. The project represents an investment of 31 billion Thai baht (approximately USD 870 million), with a designed annual throughput capacity of 7 million TEUs. As Thailand's manufacturing base expands - generating parallel growth in both machinery equipment imports and finished goods exports - Phase Four will serve a critical function, positioning the port to absorb rising long-term cargo volumes and accommodate the sustained investment inflows projected for Thailand's eastern provinces.
Trade data underscores the momentum behind these expansion decisions. Buoyed by robust global demand for data centre infrastructure and AI-related electronic components and machinery, Thailand's import and export figures for September this year exceeded market expectations. According to Port Authority data, Laem Chabang recorded an all-time throughput high of 10.2 million TEUs in the previous fiscal year; that trajectory has continued into the current fiscal year, with 7.2 million TEUs handled across the first eight months. For freight forwarders and export-oriented enterprises, the period of port expansion and concession transition warrants close monitoring of terminal operational changes, handling efficiency, and vessel schedule coordination.
