A CATHODIC PROTECTION SYSTEM (14) FOR PROTECTING AN UNDERWATER STRUCTURE (20) INCLUDES A PLURALITY OF BLOCKS (16) WHICH ARE CAPABLE OF CONFORMING TO VARIOUS STRUCTURES. EACH OF THE BLOCKS (16) INCLUDE: A FLEXIBLE WIRE ROPE (22), THE ROPE (22) CONSTRUCTED AND ARRANGED TO PASS THROUGH THE CENTER OF EACH BLOCK (16) IN TWO DIRECTIONS, AND EMBEDDED THEREIN .TO FASTEN THE BLOCKS (16) TO EACH OTHER BY ROWS AND COLUMNS; A SACRIFICIAL ANODE (48) EMBEDDED IN AT LEAST ONE OF THE BLOCKS (16), AND ELECTRICALLY ATTACHED INSIDE THE BLOCK (16) TO THE FLEXIBLE WIRE ROPE (22); AND A CONNECTING SYSTEM (18) ELECTRICALLY ATTACHED TO THE WIRE ROPE (22) AND TO THE UNDERWATER STRUCTURE (20). EACH BLOCK (16) HAS A NON-ABRASIVE PAD ATTACHED TO IT. THE PAD PROVIDES SPACING BETWEEN THE BLOCK (16) AND THE UNDERWATER STRUCTURE (20). THE SYSTEM (14) INCLUDES MEANS FOR COLLECTING PERFORMANCE DATA FROM THE SYSTEM (14). THE SACRIFICIAL ANODE (48) IS MADE OF A COMPOSITION TAKEN FROM THE GROUP COMPRISING ALLOYS OF: ZINC, ALUMINUM, OR MAGNESIUM. |
