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, a 4,500-square-foot, 2,400-gallons-per-minute filter building, a two-bay truck fill-stand, and an Additive Injection System at rail receipt yard Building 4091. The new bulk tank contains a pumphouse with multiple issue vertical turbine pumps and a water draw-off vertical turbine pump. Aboveground and underground pipe between the new structures and a transfer line to the rail offload area total 13,000 linear feet of carbon and stainless-steel pipe, fittings, and valves incorporating two isolation valve pits and 24 Hi/Lo pits. Electrical systems on the project involve medium/low voltage for Class 1 Division 1 and Division 2 environments ranging from 6.6kV to 600-volt power, lighting, instrumentation, fire protection, and cathodic protection, as well as an 880kW standby generator. The Filter Building control room will contain a new pump control Programmable Logic Controller (PLC) and Human Machine Interface (HMI), and an automatic tank gauge (ATG) reporting module capable of reporting inputs from all Eastside Fuel Facility tanks. Close-out work includes extensive testing and commissioning of the new fuel and power systems.
