Laem Chabang port, Thailand’s largest container port, is a cornerstone of the country’s logistics network. Operated by the Port Authority of Thailand (PAT), the facility follows a public-private partnership (PPP) model that combines government oversight with private sector efficiency. With global supply chains increasingly shifting towards Southeast Asia, ongoing upgrades and the Phase 3 expansion are set to strengthen the port’s position as a regional transhipment hub.
Project overview
Laem Chabang port, since its commencement in 1991, has developed into Thailand’s leading maritime hub and one of Southeast Asia most important logistics gateways. The port is located about 130 km south of Bangkok in Chonburi province. The deep-water port has grown alongside Thailand’s export-driven economy and the country’s rapidly expanding manufacturing sector. Over more than three decades, the port has undergone major upgrades and expansion phases that have steadily strengthened its capacity and global relevance.
The port was originally developed to relieve congestion at Bangkok’s older port facilities and to support Thailand’s export-oriented industrial growth. Its location along the eastern seaboard provides direct access to the Gulf of Thailand and major international shipping routes, making it ideal for handling large container vessels.
The port has grown through successive development phases. The first two phases expanded container terminals, logistics facilities and supporting infrastructure, allowing the port to gradually increase cargo throughput and handle growing international trade volumes. Over time, Laem Chabang became the primary maritime gateway for Thailand’s manufacturing exports, particularly automobiles, electronics and industrial goods produced in the surrounding industrial zones.
The port’s proximity to Thailand’s industrial corridors has made it a critical logistics hub. It serves the manufacturing ecosystem of the Eastern Economic Corridor, a major government initiative aimed at transforming the eastern provinces into a high-tech industrial and logistics centre.
Upgrading terminals
In a significant development, in May 2025, Thailand’s PPP Committee approved a THB 12.8 billion investment to upgrade Terminals B1 and B2. The project will consolidate the two terminals and extend the berth to improve operational efficiency and enable the handling of larger container vessels. The upgrade will be implemented under a PPP net cost model. The two terminals currently handle up to 600,000 twenty-foot equivalent units (TEUs) each per year and operate under separate 27-year concession agreements. Consolidating them will streamline operations and create a more efficient cargo handling system.
The project also aligns with Thailand’s 13th National Economic and Social Development Plan, which seeks to position the country as a major regional logistics and trade hub. As part of this broader strategy, the government has expanded its 2020-2027 PPP Investment Plan to include 139 projects worth around THB 921 billion across sectors such as infrastructure, public health and environmental management.
Phase 3 expansion
The most ambitious development under way at Laem Chabang port is its Phase 3 expansion project. This initiative is designed to significantly increase the port’s capacity while modernising its logistics systems. Phase 3 focuses primarily on the development of Terminal F, which will substantially increase the port’s overall container handling capacity. Once completed, the port is expected to handle approximately 18.1 million TEUs annually, positioning it among the largest container ports in Southeast Asia.
GPC International Terminal Limited, a consortium led by Gulf Energy Development Plc, along with PTT Tank Terminal Company Limited and China Harbour Engineering Company Overseas, is the primary developer and concessionaire. The project is being implemented under a 35-year PPP contract signed with the PAT in 2021 and covers the design, construction, operation and maintenance of Terminal F.
The expansion is being executed in multiple contract packages. Contract Package 1, which includes sea and coastal reclamation works valued at THB 21.32 billion, is over 90 per cent complete and is expected to be handed over by July 2026. Contract Package 2, covering road networks, buildings, utilities, service berths and domestic freight connectivity systems, is currently about 11 per cent complete. This package also supports the development of rail connectivity extending to the rear of the berths.
Dredging works form another critical component, with the port basin being deepened to approximately 18.5 metres to accommodate ultra-large container vessels. Land reclamation for the Terminal F1 area is expected to be completed by 2027, with full terminal construction scheduled for completion by 2028 and operations targeted to commence by 2031.
A key objective of the expansion is to enhance multimodal transport connectivity. Rail cargo capacity is expected to increase to about 6 million TEUs annually, with the rail modal share rising from roughly 7 per cent to around 30 per cent through the introduction of a single rail transfer operator system. This shift is aimed at reducing road congestion, improving logistics efficiency and lowering transportation costs. In turn, the expansion is expected to help reduce Thailand’s national logistics costs from around 14 per cent of GDP to approximately 12 per cent.
Focusing on digital transformation and sustainability
Beyond physical expansion, Laem Chabang port is also undergoing a significant technological transformation. As part of the Phase 3 development strategy, the port is integrating advanced digital systems to improve efficiency, safety and sustainability. Automation technologies are being deployed for container handling operations, enabling faster and more precise cargo movements. At the same time, 5G connectivity, AI and internet of things (IoT) technologies are being integrated into vessel tracking, port traffic management and logistics monitoring systems. These digital upgrades are designed to transform Laem Chabang into a smart port.
Environmental sustainability is another major focus. The port is implementing environmental monitoring systems that track air and water quality in real time. Plans are also under way to transition port equipment to electric power, reducing emissions from cargo handling operations. In addition, shore-to-ship power systems are expected to be introduced. This measure can significantly reduce emissions and noise pollution around port facilities.
Future outlook
Looking ahead, the continued development of Laem Chabang port is expected to play a decisive role in Thailand’s economic transformation. Once the Phase 3 expansion is completed, the port could become one of Southeast Asia’s largest transhipment hubs, capable of handling significantly larger cargo volumes while meeting global operational standards. The expansion is also expected to generate substantial economic benefits. Besides, improved logistics efficiency will help Thai exporters remain competitive in increasingly complex global markets.
With increasing automation, stronger multimodal connectivity and expanded capacity, Laem Chabang is positioning itself to handle the evolving demands of global shipping.
