Grangemouth Dockyard Co was established in 1885 by William Miller and Samuel Pophouse Jackson. The company started with a shipbuilding yard in Grangemouth and in 1888 acquired two yards in Alloa and Ardrossan. In 1900 a yard was acquired in Greenock and the company re-named the Grangemouth and Greenock Dockyard Co. In 1918 the Greenock yard was sold to Cayzer, Irvine & Co Ltd and the company reverted to the name Grangemouth Dockyard Co Ltd.

In 1967 it became part of the Swan Hunter Group and then became a British Shipbuilders subsidiary after
nationalisation in 1977. In November 1983 British Shipbuilders announced the closure of Grangemouth Dockyard after completion of the last contract, which was the Forth Ports Authority tug, Oxcar [source: Scotsman 5 Nov 1983]. However, it reverted to being a private company in 1984 and in 1987 it went into liquidation. From 1885-1972 the company built ships. In 1972 it stopped building ships and concentrated entirely on repairs.
