This quote from an AP article is consistent with the view expressed here after our review of the inspection reports for the Beta Unit (Platform Elly to shore) pipeline. Further per the AP article:
Safety inspections in 2015, 2017 and 2019 found anomalies in Amplify’s pipeline, including instances of metal loss and three dents that were previously repaired. But several experts who reviewed the reports said the metal loss — which can be a sign of a pipe wall thinning as it corrodes with age — was relatively minor. The dents were not in the same area as the spill.
The 16” oil pipeline was found to be in good condition with no visible damage or anomalies. One (1) CP test point that was installed in 2014 was found to be displaced from its location on the pipeline (this was also noted in the 2018 survey), and no damage was noted at the location (Fix #101).
Aqueos inspection report, May 2020
Pipe‐to‐electrolyte potential values recorded were: ‐ 921 millivolts (mV) on the 6” gas pipeline ‐ 910 millivolts (mV) on the 10” water pipeline ‐ 963 millivolts (mV) on the 10” gross fluids pipeline ‐ 906 millivolts (mV) on the 16” oil pipeline
As the NACE Standard SP0169‐2013 “Control of External Corrosion on Underground or Submerged Metallic Pipelines” criterion is ‐800 mV, all readings indicate that Cathodic Potential is within specifications.

Metal loss data from Baker Hughes internal inspection (12/2019):
The metal loss findings are consistent with those reported in a previous internal inspection (Baker Hughes, 11/2017).
BSEE has general authority to require pipeline inspections under 30 CFR 250.1005. BSEE, the State Lands Commission, and the operator appear to have implemented an effective inspection program for the Beta Unit.
