External Corrosion Direct Assessment (ECDA) and Internal Corrosion Direct Assessment (ICDA)


Safe and continuous operation of underground pipelines is a matter of primary importance in the oil, gas and chemical industries. Failures by corrosion are one of the major and most frequent causes of incidents and environmental disasters worldwide.

External Corrosion Direct Assessment (ECDA) and Internal Corrosion Direct Assessment (ICDA) are structured processes that intend to improve safety by assessing and reducing the impact of internal and external corrosion on pipeline integrity. The main goal is to identify and address corrosion activity, to repair corrosion defects and remediate the cause, and to prevent corrosion defects from growing to a size that is large enough to impact structural integrity. NACE already issued the Standard and Recommended Practice for ECDA and Standard for ICDA.

When new Standards or Recommendations are announced, it is always difficult to find the connection between the requirements of the Standards and the meantime developed new technological tools. In most cases we are loosing some years, before the equipment manufacturers are converting their systems for the new demands. Our advice is, to analyse all the available technologies with their limitations, and to combine them in a good way to provide the necessary information. Our company has already developed the practical solutions for the Direct Examination, and we would like to share our findings with our clients during projects. Our main goal is to show a technical package for the ECDA and ICDA processes which is economical, easy to apply and accurate.
