Abstract: Operators who choose to assess their pipelines in High Consequence Areas (HCAs) by using the External Corrosion Direct Assessment (ECDA) methodology need to clearly define the integrity threat(s) associated with cased pipelines in order to select the correct methods for assessing cased pipelines.

 Operators who choose to assess their pipelines in High Consequence Areas (HCA’s) by using the External Corrosion Direct Assessment (ECDA) methodology need to clearly define the integrity threat(s) associated with cased pipelines in order to select the correct methods for assessing cased pipelines.  The guidelines offered in the National Association of Corrosion Engineers’ (NACE) ECDA procedure 0502-2002 are somewhat unclear in their guidance.  This study will examine the likely threats associated with cased pipeline crossings and develop a list of existing tools and processes available to assess for threats.
