Abstract

FPSO (Floating Production Storage and Offloading) is an oil and gas transportation vessel, currently considered effective in the oil sector. However, the vessel possesses several limitations, including corrosion on the material steel. ICAF (Impressed Current Anti-Fouling) is a suitable preventive method for biological corrosion. The study of biofouling-causing macroalgae was performedona laboratory scale with a simple ICAF system, using the variables of operating time, as well as 10, 20 and 30 cm anode-cathode distances. Furthermore, physical observation was conducted to ascertain Barnacle removal, while the Cu ion concentration was determined using AAS (Atomic Absorption Spectrophotometry). This study aimed to determine the removal of Barnacle macroalgae, using a simple Impressed Current Anti-Fouling system. According to the results, the highest removal of 100% was obtained at all anode-cathode distances used. However, the fastest removal was attained using a 10 cm anode-cathode distance and 9 A of electrical current. Meanwhile, the highest Cu ion concentration produced while operating the simple ICAF system was about 81.85 ±3.04 mg/l. Therefore, the Cu ions generated during the system’s operation were able to remove Barnacles from adhering media.
