NASA John C. Stennis Space Center Sitewide Cathodic Protection Refurbishment
Date: November 2016 – October 2017
Location: NASA John C. Stennis Space Center
Client: NASA
Thousands of linear feet of piping run underneath the surface and provide key service media for the rocket testing operations conducted at the NASA Stennis Space Center. While NASA continues to follow suit with the current industry practice of opting for above-ground piping in lieu of underground installations, it maintains a great deal of legacy piping underneath the soil.
Rather than abandoning all such piping in place, NASA sought to extend the life of the underground pipes as much as possible by revamping and/or replacing the cathodic protection (CP) system. An outside specialist was contracted to design and install this new CP system . During the installation phase, our inspection team served as third party Quality Assurance oversight on behalf of NASA to ensure the contractor was meeting specifications and industry standards related to the installation of CP.
