Chennai Port is set to undergo a major expansion with the revival of its ambitious Outer Harbour Project, planned at an estimated cost of ₹8,000 crore. The first phase of the project is expected to be completed by 2031, significantly boosting the port’s capacity and enabling it to handle some of the world’s largest vessels.
Officials from the Chennai Port Authority said the proposed Outer Harbour will be developed seaward, beyond the existing harbour line, to create additional capacity and reduce logistics time and costs. With a planned draft of over 20 metres, the new facility will be capable of accommodating ultra-large container ships carrying more than 20,000 TEUs.
The project will be implemented on a Design-Build-Finance-Operate-Transfer (DBFOT) model. A transaction advisor will soon be appointed to carry out a feasibility study, and the concessionaire is expected to be finalised by the end of 2026. The successful bidder will be granted a 45-year concession period.
Construction will take place in phases, with the first stage designed to handle vessels with an 18-metre draft. Future phases will upgrade the port’s capacity to handle ships with drafts of up to 21 metres, keeping pace with evolving maritime technologies.
According to the Request for Proposal (RFP), the project will involve building a breakwater, reclaiming land for yard development, constructing berths, developing container yards, roads, internal rail connectivity, dredging of the basin and channel, and installing handling equipment, navigational aids, tugs, and other floating crafts.
This is the third attempt to launch the Outer Harbour Project, after earlier efforts in 2007 and 2013 failed to attract sufficient private participation. The initial plan, conceived in 2007, envisaged a mega container terminal north of Bharathi Dock with a 2-km quay length and 4 million TEU capacity. Despite a feasibility study by IIT-Madras, the project saw limited response from potential bidders at the time.
Now, with Tamil Nadu witnessing rapid industrial growth and increased demand for transshipment facilities, the Chennai Port Authority has revived the project to meet the region’s evolving maritime and trade requirements.
The initiative coincides with the development of the Chennai Port–Maduravoyal Elevated Corridor, which aims to streamline port connectivity. The corridor’s dedicated lanes and multiple ramps will help segregate port traffic from city vehicles, easing congestion and improving cargo movement efficiency as Chennai positions itself as a key maritime hub in South India.
