Yokota Air Base, Japan



Construct Jet Fuel Bulk Storage Tanks, Phase 1, Yokota AB, Japan

This project is a Joint Venture with Japanese construction firm, Obayashi Corporation. The scope of work for this project at Yokota Air Base in Japan is to construct a 100,000-barrel cut-and-cover JP-8 fuel storage tank, filter building, and two-bay truck fill-stand. The new bulk tank contains a pump house with 600-gallons-per-minute (gpm) issue vertical turbine pumps and a 50-gpm water draw off vertical turbine pump. The new Fuel Storage includes a pump vault and filter separator building. Medium/low voltage Class 1 Division 1 & Division 2 environments for power, lighting, instrumentation, fire protection, and cathodic protection are included, as well as a standby generator. The work includes extensive testing and commissioning of the new fuel and power systems. The tank includes a high-level valve, independent level alarms, and hardware necessary for the installation of automatic tank gauging (ATG) systems. The tank includes piping, valves, vaults, and appurtenances from tanks to the filter separator building. The Filter Building control room will contain a new pump control Programmable Logic Controller (PLC) and Human Machine Interface (HMI), an automatic tank gauge (ATG) reporting module capable of reporting inputs from all Eastside Fuel Facility tanks. Nova-Obayashi will also provide a product saver tank for each bulk tank. The filter building contains 600-gpm issue filter separators, 2,400-gpm micronic filters, and 1,200-gpm receipt filter separators and backups as needed. Crossover piping between the new and existing filter buildings will provide issue capability from any tank to any truck fill stand location. The new filter building and pump house include fire alarms and transmitters compatible with the base’s systems, control panel, automatic detection system, and manual pull stations. The filter building includes a plumbing system and control facilities.
