A laboratory flow loop is used to evaluate the ability of an on-line, electrochemical, biofilm-activity probe to monitor biofilm activity in synthetic oilfield brine and correlate its activity to localized pitting corrosion. In addition, bio-traps containing porous polymer beads for trapping biomass are evaluated as a rapid means to evaluate biofilm community structure.
How calcareous deposits formation in seawater influences the performance of a galvanic cathodic protection (CP) system in seawater. Coupling current measured. A resistance set between the cathode and the anode simulated circuit resistance of CP. Steel cathode potential over immersion time. Calcareous deposits analyzed by X-Ray Diffraction.
Challenges associated with coordinating the modelling, design, and installation of an alternating current interference and mitigation systems. The project consisted of a 65 kilometer long double circuit 500 kilovolt (kV) overhead transmission in a heavily congested right-of-way corridor with more than 80 pipelines.
