A recent study of operations and maintenance of Alyeska’s cathodic protection system found that the program was “very good;” however improvements are still needed.
National Pipeline Services, a consulting company that specializes in cathodic protections, conducted the study for the Council. They looked specifically at the systems that prevent corrosion in the metal piping that carries crude oil through the terminal to the large oil storage tanks.
The researchers based their report on a review of documents, procedures, testing, and results from previous inspections of those systems.
The final report summarized the systems currently in use at the terminal, as well as Alyeska’s methods for monitoring and testing the systems.
