Weston self-performed routine out of service inspections for Tanks 43-5 and Tank 2076 at the bulk storage facility serving Defense Fuel Support Point (DFSP) Jacksonville, FL. Tank bottom inspections found severe underside corrosion impeding the tanks from returning to service and the Cathodic Protection loop had failed. Weston was awarded the design and installation of a new second bottom with new cathodic protection, sand, and tank appurtenances. The tank shell was 100% radiographed and a hydrostatic pressure test was performed by filling the tank 24 hours a day, and the discharged water was tested to ensure release to the environment was safe. Weston made the mandatory and recommended repairs to ensure suitable long-term service, reduce the risk of corrosion, and validate to the state of Florida, DoD, and the Department of the Navy that these API 653 tanks can be returned to service without threat of leaking. Our design-build construction team returned the tanks to service on schedule and performed 25,000 reported manhours with zero safety or quality incidents, reducing the client’s associated risk at NAVFAC facilities.
