DIRECT ASSESSMENT PROJECT REVIEWS

With the increased focus on traceable, verifiable, and complete
documentation, EN Consulting performs documentation and survey data reviews
of historical ECDA and ICDA projects to assess the completeness, and ensure
the assessment has been performed per the intent of applicable pipeline
regulations and operator-written plans and procedures. During a typical
review, EN Consulting evaluates items including:

Direct examination:

  • Appropriate number of direct examinations performed
  • Locations selected for direct examination warranted based on indication
    classification and prioritization (elevation profile for ICDA)
  • Additional direct examinations performed as required based on initial
    direct examination results
  • Confirm that direct examination locations identified on dig lists were the
    locations where direct examinations were actually performed
  • Completeness of dig forms

Post-assessment:

  • Remaining life and reassessment interval calculations
  • Assessment of ECDA effectiveness

DIRECT ASSESSMENT PLAN REVIEWS

With recognized code compliance experts on staff, EN Consulting performs
reviews of operator-written ECDA and ICDA procedures to assess alignment
with all applicable code requirements, jurisdictional inspection protocols
and industry guidance documents
