A piece Maritime and David Brown's Gearbox Company history.
HMS Ark Royal. 1981 - 2013.
Royal Navy Aircraft Carrier, Commissioned by The Queen Mother 1st November 1981.Being the largest aircraft carrier within the British fleet at the time.
The Ministry of Defence - December 2010, made a decision to decommission her, options were to moor her as a hotel, museum ship/ visitor attraction or even a casino !
The Ark was towed out of Portsmouth Dockyard on 20 May 2013, destine for The Leyal ship recycling site in Turkey for scrap. At a price of around £2.9m.
The Gearbox was extremely large, In fact, it was designed and planned never to take the gearbox out of the ship, Far too large to remove in one piece. in fact large enough that for servicing and repairs, as a safety precaution several steel rods were place through the outer casing from side to side and then padlocked in position, these locked the gearing.
One of the mechanics would then have to climb into the gearbox to carry out servicing/maintenance or repairs.
Plate is 25 x 10 inches.
If you look at the edges of the plate you can see the many layers of "Battle Ship Grey" paint.
