Results of a 4-year field program on the use of coupons to monitor the adequacy of the Trans Alaska Pipeline System's (TAPS) cathodic protection (CP) systems are discussed. The objective was to evaluate the use of coupons to correct for IR-drop, anode/pipe mixed potentials, and Telluric currents. Field and supporting laboratory programs were used. It was found that coupons adequately monitor the TAPS CP systems.
