THE IMPORTANCE OF INTERNAL CORROSION MONITORING IN SEAWATER TREATMENT AND INJECTION PLANTS FOR INTEGRITY MANAGEMENT Internal corrosion monitoring in operating facilities can be conducted with online monitoring equipment that include Corrosion Coupons Corrosion Probes Bio probes etc. installed at key locations within the facility. In conjunction with corrosion monitoring fluid analyses activities can also be carried out for different processes to determine various key parameters such as pH conductivity TDS Total Hardness Dissolved Oxygen content scaling elements concentrations Corrosion and Scale Inhibitor residuals Fe content (total and dissolved) bacterial activity etc. Corrosion data and fluid characteristics can then be analyzed for trends and appropriate recommendations issued to asset owners for corrective and/or preventive measures to mitigate corrosion and also to advise Inspection requirements.This paper highlights two facilities at the Kuwait Oil Company (KOC) the Sea Water Treatment Plant (SWTP) and Central Injection Pump Facility (CIPF) where internal corrosion monitoring and fluid analyses are carried out on a routine basis. Results from these activities have been utilized to compare with actual findings during facility shutdown to evaluate the monitoring/mitigation efforts which have contributed to the integrity of the plants
