Protecting DTA's Wharf From Corrosion

Dominion Terminal Associates (DTA) is a coal shipping and ground storage facility located on the East Coast of the USA in Newport News, Virginia. The reinforced concrete structures at DTA include a ~1500 ft concrete wharf, used by large cargo ships for loading/unloading coal to/from the terminal. 

 As a marine structure, DTA’s concrete wharf is exposed to a harsh environment with ideal conditions to facilitate corrosion of the reinforcing. Having performed rounds of concrete restoration in the past, DTA was frustrated at the speed with which the repairs failed due to ongoing corrosion. Looking for a solution that could mitigate the corrosion of the reinforcing steel and extend the service life of the structure, DTA looked to cathodic protection as a possible answer. 

 Upon consultation with their engineering team, DTA opted to invest in a CASETTE^TM Impressed Current Cathodic Protection (ICCP) system to be installed on the concrete wharf elements located in the splash zone. Installation commenced in 2022 and is ongoing.
