On St. Paul Island, TDX Fuels manages two 500,000-gallon bulk storage tanks, totaling one million gallons of storage. These tanks receive fuel from a marine header and supply fuel to various local facilities, including a truck loading rack, a seafood processing plant, and a marine fueling system for fishing vessels. The project's scope involves designing a tank gauging system using a TMS 4000 and implementing an entirely new system due to corrosion-related issues, including the loss of the truck loading rack and heavily corroded piping. Our design includes a new truck loading rack with canopy, a stainless-steel cabinet for the marine header, and roughly 1,000 feet of underground piping with passive cathodic protection. Despite facing challenges such as the corrosive environment, restrictive lot lines, and numerous undocumented buried utilities, compounded by the island's remote location southwest of the mainland, KRC devised strategies to overcome these obstacles ensuring the successful completion of this project.
