. Cathodic protection system for fleet moorings. Ocean engineering; Buoys; Moorings. Figure 12. Cable silver-soldered to chain link. Specialized Zinc Anodes With Steel Cables Repairs and Fabrication. The modification of the cathodically protected mooring was accomplished when both it and the unprotected control mooring were scheduled for their periodic removal and rehabilitation ashore. The total cost for rehabilitation of the control mooring amounted to $4,617 of which $2,000 was for pickup and installation and $2,617 was for repairs. The unprotected ground ring assembly was loose, and all rivets needed replacing. The pear links were badly pitted, and the thickness was reduced in places to 1-1/2 inches (a loss of 40%), necessitating their replace- ment (Figure 13). The chain thickness for the first five links on all legs had been reduced to about 1-7/8 inches. The cathodically protected mooring required no repair work, but the ground tackle was recoated by dipping the sandblasted chain into a tank of cold-applied coal tar coating. Ml L-C-18480A. The anodes on the ground legs had lost very little zinc while providing the current necessary for cathodic protection. Those nearest the ground ring had generally lost slightly more zinc, because higher potentials had been provided in these areas. The two smaller anodes located in the sea chests built into the buoy cone also had lost relatively little zinc. 22.
