Summary:
The Gas Technology Institute (GTI) and the American Gas Association (AGA) have developed a collaborative research program to help Local Distribution Companies who operate high-pressure natural gas transmission lines understand the methods and procedures to perform integrity assessments and meet government-imposed regulations. This program includes the development of a standard External Corrosion Direct Assessment (ECDA) inspection protocol after taking into consideration other ECDA research efforts and program member input. This document is a "generic" protocol that assists companies in the implementation of NACE Standard Recommended Practice - RP 0502, "Pipeline External Corrosion Direct Assessment Methodology". It is assumed that the user of this protocol has become familiar with NACE RP 0502 and the associated terminology used throughout the recommended practice. The NACE ECDA RP directs users to develop procedures, methods, criteria, etc. to carry out many of the action items required for Direct Assessment. Therefore, this protocol was developed to aid program participants in understanding and developing these methods. In addition, it will standardize the assessments done throughout the program. This will allow all of the data collected to be compared which will help estimate the reliability of various indirect examination tools under specific conditions and identify possible enhancements to the NACE ECDA RP. When there is a conflict between this document and NACE ECDA RP 0502, the NACE RP supersedes the protocol. Where there is a conflict between this document or NACE ECDA RP 0502 and DOT RSPA 49 CFR PART 192, "Pipeline Safety: Pipeline Integrity management in High Consequence Areas (Gas Transmission Pipelines); Final Rule, 49 CFR PART 192 supersedes.
