* API 650 / 653 Standards
Local and International Environmental Protection Standards ?Corrosion control requires periodic monitoring, historically performed on site by direct NDT, on line measurements
?The need to maintain an integral asset to prevent loss of production and subsequent opportunity costs ?Provide cost effective inspection program to maintain asset integrity
?Implement Corrosion Monitoring & Preventive Maintenance Inspections Program
?Risk Assessments
