Pond was contracted by ExxonMobil to conduct an external corrosion direct assessment (ECDA) on the Beaumont to DuPont Hydrogen Line MR-27, which spans 3.11 miles (16,431 feet) of 10-inch hydrogen gas transmission pipeline in Beaumont, Texas. The ECDA process is a four-step approach aimed at assessing the integrity of a pipeline where external corrosion is identified as a primary threat. The four-step ECDA process includes pre-assessment, indirect inspection, direct examination, and post-assessment. This indicates a thorough assessment and maintenance process aimed at ensuring the continued safe operation of the hydrogen gas transmission pipeline.
