The liquid petroleum internal corrosion direct assessment (LP-ICDA) method and its four steps: (1) pre-assessment, (2) indirect assessment, (3) direct examination, and (4) post assessment.
NACE external corrosion confirmatory direct assessment (ECCDA) process for buried onshore ferrous piping systems. The process is also predictive.
NACE external corrosion confirmatory direct assessment (ECCDA) process for buried onshore ferrous piping systems. ECCDA is meant to improve pipeline safety and locates areas where corrosion is likely to occur.

Control de corrosión en tanques subterráneos mediante protección catodÍca (CP). Tanques de acero dulce y partes metálicas . Criterios, diseño, instalacción, mantenimiento.
Requirements to ensure adequate isolation of cathodically protected pipelines, especially those with high-quality dielectric coatings.
In 1998, pipeline operators began to use a instrumented inspection technology that we now know as guided wave testing (GWT), which detects changes in the cross-sectional area of the pipe wall.
