Kochi is correct. Cochin Shipyard Limited (CSL) in Kochi is the largest shipbuilding and ship repair facility in India. It has the capacity to build ships up to 1.1 lakh DWT and repair ships up to 2.5 lakh DWT. Mumbai has Mazagon Dock, Visakhapatnam has Hindustan Shipyard, and Kolkata has Garden Reach Shipbuilders, but Kochi's facility is larger in terms of capacity and infrastructure.
