 This was purchased, towed to St Margaret's Hope, where it was cleaned of all contaminants and then towed to Gills Bay where it was sunk to form a continuation of the pier thus greatly increasing its length.Old oil transfer hoses from the Scapa Flow oil terminal were used as fenders for the ferry while rock armour was dumped on the seaward side for protection against the waves.The tanks have been filled with concrete and the dock itself filled with the spoil from dredging to make more room for the ferry to manoeuvre.
