| Description |
Pipelines cost an average of US$9,000 per kilometre to maintain, and management is worried about low oil prices. Have you made it clear enough to the decision-makers that pipeline corrosion assessments are an urgent priority? Do you have the cost-effective solutions you need?
External Corrosion Direct Assessment (ECDA) is a structured process you can use to evaluate pipeline integrity, as also used by some of the world’s top pipeline operators. The ECDA goal is to enhance safety by managing the risk of pipeline corrosion failures, while minimising the cost required for excavations and repairs. It does this by helping you identify and address corrosion activity, proactively preventing external corrosion defects from growing to a size that is large enough to impact structural integrity.
ECDA is a continuous improvement process. Through successive applications of ECDA, you can identify and address where corrosion activity has occurred, is occurring, or may occur. You can then use these results to prioritise future actions.
This technique may also be used where more established methods such as inline inspection (ILI) and pressure testing are not possible or not practical.
Trained and experienced staff and specialised field equipment are necessary to obtain reliable and meaningful results. Without training, the ECDA data collected, recorded and analysed will produce unreliable or meaningless conclusions. Attend this workshop to learn the proper methods for collection, recording, and analysis of data for ECDA.
This workshop will focus on critical areas of the pipeline integrity management (PIM) plan, identifying high consequence areas and maximising the benefit of your training. The trainer will also demonstrate the latest software you can use to undertake the entire ECDA process in one programme, in line with the NACE SP0502 ECDA Standard.
