The winches ashore were embedded in concrete to a depth of 14 ft. and on the surface attached to the inside of the piles was a heavy green heart log which was intended to bear the strain of the purchase on the parbuckling wires that were used for the uprighting process. The wires from the shore winches were led over the dock wall and were made fast to' the dredger on the port side on which she lay. While the enormous purchase was in operation from the shore the dock board's powerful new lifting camels of 1,000 tons capacity each with the assist- ance of other salvage craft were made fast with wires ranging from 200 to 230 tons breaking strain.
