Shipbuilding

Tamil Nadu is emerging as India’s leading shipbuilding and maritime manufacturing hub, strategically positioned with access to both the eastern and western coastlines. The state’s shipbuilding ecosystem encompasses design, construction, repair, and component manufacturing, supported by modern ports, skilled engineering talent, and robust industrial linkages with the steel, machinery, and electrical sectors. Key hubs, such as Chennai, Thoothukudi, and Cuddalore, are fostering shipyard clusters, dry docks, and marine fabrication facilities, anchored by major players and MSMEs. With global partnerships and growing demand for coastal and offshore vessels, Tamil Nadu is rapidly expanding its presence in commercial and offshore structure capabilities. The state is also promoting specialized maritime industrial clusters, workforce training, and sustainable ship technologies to position itself as a vital node in India’s blue economy and global maritime value chain.

The greenfield clusters are planned as fully integrated industrial zones, equipped with comprehensive common infrastructure across both seaside and landside components.

Robust Port Network Fueling Growth

The state is supported by an extensive maritime network of 3 major ports and 14 non-major ports, forming a well-distributed port ecosystem along the coastline.

Thoothukudi Leading India’s Hydrogen Future

Thoothukudi is one of the three nationally recognised green hydrogen hubs in India, with a planned capacity of around 5 million metric tonnes per annum (MMTPA). Its strategic coastal location, port infrastructure, and access to renewable energy make it well suited for large-scale green hydrogen and green ammonia production.
