The Government of India is advancing a major maritime infrastructure investment programme worth approximately ₹18,437 crore at V.O. Chidambaranar (VOC) Port in Thoothukudi, Tamil Nadu. The initiative is aimed at expanding port capacity, improving international shipping connectivity and positioning southern Tamil Nadu as a significant hub for global trade, industrial development and renewable energy logistics. The programme brings together three major developments: the ₹17,167-crore Outer Harbour Development Project, a ₹520-crore container terminal at Berth No. 7 and a proposed ₹750-crore offshore wind terminal.
The investment drive reflects the Union Government’s broader strategy to modernise India’s ports, accommodate larger vessels and strengthen logistics infrastructure supporting manufacturing and exports. During his address in Chennai on 11 October 2026, Prime Minister Narendra Modi highlighted the planned investment of approximately ₹17,000 crore to transform VOC Port into a world-class mega container port and green energy hub. The initiative is expected to enable ultra-large container vessels to call at Thoothukudi while strengthening Tamil Nadu’s position in international transportation and industrial supply chains.
The Outer Harbour Development Project represents the largest component of the investment programme. Approved by the Cabinet Committee on Economic Affairs in September, the project envisages deep-water harbour infrastructure and new container terminals designed to accommodate some of the world’s largest container ships. Once developed, the expanded facilities are expected to improve the port’s ability to handle international container traffic, strengthen maritime connectivity and provide exporters across southern India with improved access to global markets.
Alongside the Outer Harbour project, the ₹520-crore development of Berth No. 7 is intended to increase VOC Port’s existing container-handling capacity. The additional infrastructure is expected to support growing cargo volumes and improve operational capabilities as international trade expands. The proposed ₹750-crore offshore wind terminal will complement these developments by providing specialised facilities for India’s emerging offshore renewable energy industry, helping establish the port as a logistics base for future offshore wind projects.
These infrastructure developments formed a key part of the visit by Vijay Kumar, IAS, Secretary of the Ministry of Ports, Shipping and Waterways, who reviewed major projects and green maritime initiatives at VOC Port on 20 October 2026. During the visit, he inspected the Green Hydrogen Pilot Plant, wind energy facilities and pilot methanol bunkering and refuelling infrastructure. The programme also included the inauguration of shore power facilities, additional mooring infrastructure and other operational improvements designed to support cleaner and more efficient port activities.
As part of the port’s environmental initiatives, the Secretary flagged off 13 electric trucks at the Tuticorin International Container Terminal (TICT). The visit also included the presentation of awards recognising achievements and excellence in port operations and development. These initiatives underline the port’s efforts to incorporate cleaner transportation, alternative fuels and energy-efficient technologies into its operations, complementing the wider investment programme in container infrastructure and renewable energy facilities.
Digital transformation and industrial development also featured prominently during the review. The Secretary examined VOC Port’s Digital Twin and Port GPT initiatives and held discussions with terminal operators, traders and other maritime stakeholders. Port-led industrialisation and the proposed mega greenfield shipbuilding cluster were among the topics discussed, reflecting the potential to connect port expansion with manufacturing, shipbuilding, logistics and other maritime industries. Such integration could help create new commercial opportunities and strengthen the regional maritime ecosystem.
The combined investments are expected to improve the competitiveness of exporters, shipping companies, logistics operators and manufacturers across southern Tamil Nadu and neighbouring regions. Greater access for large container vessels, increased cargo-handling capacity and specialised offshore wind infrastructure could attract additional industrial investment and strengthen international trade links. The programme aligns with the Union Government’s Maritime Amrit Kaal Vision 2047, which seeks to modernise India’s maritime infrastructure, expand shipping capabilities and enhance the country’s role in global maritime trade. The project details and developments were announced in a press release issued by the V.O. Chidambaranar Port Authority.
