The Plan to Raise & Stabilise Cerberus.

Step 1 (Guns off) A barge with crane would moor alongside Cerberus and lift the four 18 ton guns from the turrets. The guns would be stored on the seafloor which would help leach salt from them. They would be returned to the ship during step 3. Completed March 2005
Step 2 (Beams on & Piles in) A crane is used to lift longitudinal beams into place which are bolted to the 8" armour plating belt on the main deck, breastwork and turrets. A second barge is used to drive piles into the seafloor along both sides of the ship.
Step 3 (Raise and Stabilise) Finally the overhead jacking frame is constructed and jacks fitted. Next the ship is raised higher than required so that the substructure of supporting beams can be installed under the ship. Lastly the ship is lowered onto the supporting frame. The overhead jacking frame is removed and the piles are cut off below the waterline. The guns are then returned to the ship.
