Bulk Fuel Storage Tank; RAAF Darwin, Australia
This extensive fuel project, performed as a Joint Venture with Nova’s Australian sister company, Nacap, constructed two 50,000-barrel cut-and-cover bulk fuel storage tanks, two pump houses, a 3,610-square foot fuel filter building, a 2,789-square-foot petroleum operations building, two 50,000-gallon drop tanks, one 4,000-gallon product recovery tank, and a 4,000 gallon waste tank, as well as fuel filling and unloading stands to support United States Air Force (USAF) missions at Royal Australian Air Force Base (RAAF) Darwin. The significant fuel equipment included vertical turbine fuel pumps, control and isolation valves, truck loading and off-loading, as well as aboveground stainless-steel piping, along with 900 linear feet of 12-inch stainless steel transfer pipeline with 3 low point drain pits. This effort included extensive testing and commissioning of the new fuel and power systems. The project also involved relocation of an RAAF-owned Liquid Dry Breathing Oxygen facility. The vertical facility construction consisted of reinforced concrete slab on grade and steel rigid frames with metal purlins and girts to frame the exterior roof and walls. Nova Nacap poured 6,000 cubic yards of concrete at various tank and building slabs, plus tank encasement and tank access tunnels. Other work included medium/low voltage Class 1 Division 1 and Division 2 environments for power, lighting, instrumentation, and cathodic protection. Additionally, the work included modification of the existing fire protection water system to support operation of USAF fuel facilities and all utilities, site improvements, pavements, communications infrastructure, backup generator, and other work necessary to provide complete and usable facilities.
