Cathodic Protection System Repair

1. The dock structures at the Balzano and Broadway terminal are divided into five cathodic protection sections named Berth 2, Berth 3, Berth 4, Berth 4 Extension, and Berth 5, and consisting of individual pipe piles and sheet piles which are supposed to be electrically continuous by bonded cables. Each berth contains a separate impressed current cathodic protection system 2. Berth 2 is approximately 360’ long; Berth 3 is approximately 500’ long; Berth 4 is approximately 750’ long; and Berth 4 Extension is approximately 300’ long. Berth 5 is a former dry dock and is approximately 900’ long, and now part of deficient operation with suspicion for also requiring repair. 3. Each contains a separate ICCP system and is individually rectified by oil cooled units of varying DC output voltages and amperage ratings. Multiple permanent CSEs were installed throughout the berths along with MMO tubular anodes.
