In August 1979 "Warrior" began her journey to her temporary home in the Coal Dock at Hartlepool for restoration as a museum ship. She arrived on 2 September 1979 and began the £9 million restoration project, largely funded by the Manifold Trust. The Maritime Trust decided to restore "Warrior" to her 1862 condition with the aim that no further major work would be necessary for the next 20 years. The first two years of the restoration were generally devoted to safely removing material added after her first commission, like the poop deck and the of concrete decking. Intensive research was done to find detailed descriptions of the ship and her equipment as of 1862 to make the restoration as accurate as economically feasible. Sources included surviving official records, and the papers of those who had served on the ship during her active service. Bolt-holes and ridges in the paint gave clues to the location of some fittings and fixtures, and the sketch plans of Midshipman Henry Murray, found in Captain Cochrane's Letter Book, showed the locations of the armament, moveable fittings and stores.
