Goa Shipyard Limited (GSL) is a public sector undertaking for defence ship building located on the West Coast of India at Vasco da Gama, Goa. It was established in 1957, originally by the colonial government of the Portuguese in India as the "Estaleiros Navais de Goa",[2] to build barges to be used in Goa's growing mining industry, which took off after the establishment of India's blockade of Goa in 1955. In the wake of Portugal's defeat and unconditional surrender to India following the 1961 Indian annexation of Goa, it was requisitioned to manufacture warships for the Indian Navy and the Indian Coast Guard.
GSL is undergoing a modernisation of its yard to adapt to the latest technology in shipbuilding. To this purpose it is negotiating with well-known shipbuilders for an arrangement to collaborate. To date it has built 167 vessels, including barges, tugs, landing craft, offshore patrol vessels and other vessels for the Indian Navy and Coast Guard and for export to countries like Yemen.[3] Goa Shipyard unlike Cochin Shipyard and Hindustan Shipyard cannot manufacture big vessels of capacity above 15,000 DWT, the average Deadweight Tonnage (DWT) capacity of a ship worldwide is around 60,000 to 80,000 DWT.
A new slipway has been commissioned to take up major repair jobs of ships in the dry dock area.
