Cockatoo Docks & Engineering Company
The Cockatoo Docks & Engineering Company was a ship building and maintenance company which operated the Cockatoo Island Dockyard on Cockatoo Island in Sydney, Australia between 1933 and 1992. History

The Cockatoo Docks & Engineering Company commenced trading on 1 March 1933 taking a 21-year lease over the dockyard on Cockatoo Island from the Federal Government. Having held a minority shareholding since 1937, in 1947 Vickers-Armstrongs became the majority shareholder. In February 1954, the lease was renewed for a further 20 years and 8 months, and again from 1 January 1972 for 21 years. In February 1984, Vickers merged its Australian interests were with the Commonwealth Steel Company to form Comsteel Vickers, Vickers and BHP each owning 38%, with the remaining 24% held by smaller investors. On 4 June 1986, the company was purchased by Australian National Industries (ANI). As part of a review of Australia's ship building capabilities, the Federal Government decided in 1987 the lease would not be renewed. Although consideration was given to terminating the lease early, in the end it ran its course until 31 December 1992, although the only work performed in the last 18 months was decommissioning the dockyard. A lengthy legal action over various costs and liabilities between the government and ANI was settled in May 1997. Ships built
