State-owned Cochin Shipyard Ltd (CSL) is planning investments of around ₹6,000 crore across two projects in Kerala and Tamil Nadu, as it seeks to expand capacity for building and repairing vessels. The proposed investments comprise a steel-block fabrication facility at Vallarpadam in Kochi and a shipbuilding and repair unit at VO Chidambaranar (VOC) Port in Thoothukudi. The projects are at different stages of preparation, and the final costs and timelines have not been established for both.
The larger component is the Vallarpadam facility, for which CSL expects to invest approximately ₹3,000 crore to ₹4,000 crore. Chairman and managing director Jose VJ said the company plans to lease about 78 acres: around 60 acres from Cochin Port and 18 acres from the Kerala government. The facility would produce steel blocks, the prefabricated sections assembled to form a ship’s structure.
The plan is linked to CSL’s expanded dry-dock infrastructure. Jose said existing steel throughput is insufficient to serve the company’s new, larger dry dock and its plans to build bigger vessels. Increasing block-fabrication capacity could help address that constraint and support the construction process before ship sections are moved for assembly. The investment’s eventual scale and schedule will depend on project planning and the arrangements for securing the land.
CSL’s newer Kochi infrastructure includes a 310-metre dry dock inaugurated in January 2024. The government says it can handle large and technologically specialised vessels, including aircraft carriers, tankers and merchant ships. The shipyard also developed an International Ship Repair Facility on Willingdon Island, equipped with a ship lift, six workstations and associated facilities. Ship-repair operations at that facility began in August 2024, according to CSL.
The second proposal is for a unit at VOC Port in Thoothukudi, focused on ship repair and the construction of small and medium-sized vessels, including tugs. CSL’s preliminary estimate is between ₹1,500 crore and ₹2,000 crore. Jose said the final investment would become clearer after a detailed project report is prepared, signalling that this figure remains an early assessment rather than a settled project budget.
There is also a more concrete step at Thoothukudi. A September project update said CSL had paid ₹280 crore for land for a proposed hybrid shipyard and received an allotment letter from the port authority. The site is planned across 110.14 acres of land and 17.29 acres of waterfront, with phased handovers extending through December 2027. The planned facility is intended for shipbuilding, ship repair and offshore fabrication.
The Thoothukudi proposal sits within a broader push to establish the port region as a shipbuilding centre. Tamil Nadu announced shipyard plans in 2025, including a proposed CSL commercial shipyard, while the state and VOC Port have been developing a wider shipbuilding cluster. These initiatives point to a mix of company-level investment and shared infrastructure development; they should not be confused with CSL’s preliminary ₹1,500–2,000 crore estimate for its own unit.
The expansion comes as CSL reports a substantial order pipeline. The company said its order book stood at around ₹22,300 crore, comprising ₹21,100 crore in shipbuilding and ₹1,200 crore in ship repair. Jose also said CSL had emerged as the lowest bidder for five Next Generation Survey Vessels for the Indian Navy, with an order value of around ₹5,000 crore. The contract had not been signed and was therefore not yet included in the order book.
National policy is also seeking to strengthen domestic shipbuilding, through measures including shipbuilding clusters and a proposed Maritime Development Fund. Together, the projects would extend CSL’s presence beyond its Kochi base and add fabrication, construction and repair capacity. Whether the investment plan delivers that expansion will depend on detailed project planning, land arrangements and execution.
