Kvaerner Govan Ltd (KGL), located at Govan in Glasgow on the River Clyde, was a shipyard subsidiary formed in 1988 when the Norwegian group Kvaerner Industrier purchased the Govan Shipbuilders division of the nationalised British Shipbuilders corporation. Prior to the Govan Shipyard's nationalisation in 1977, as a result of the Aircraft and Shipbuilding Industries Act, it had been operated by Govan Shipbuilders Ltd, which emerged from the collapse of the previous Upper Clyde Shipbuilders (UCS) joint venture in 1972. Prior to the formation of UCS in 1968, the Shipyard was operated by the Fairfield Shipbuilding and Engineering Company, which had a history extending back to 1834.
