Description: This design/build helicopter refueling system began as a design contract with an architectural firm in Washington, D.C. Once
the design was completed, ASI was asked to submit a proposal to the general contractor and was eventually awarded the contract on the basis of technical merit and past experience.

The scope consists of installation of a 12,000-gallon double wall fiberglass Jet Fuel UST with deadman system, a Pump/Filtration Skid (PFT), a Remote Dispenser Skid (RDS), and a Veeder Root TLS-300C leak detection system. The PFT will off load fuel transports at 200 USGPM; the RDS will dispense into helicopters up to 60 USGPM. The underground piping consists of double wall fiberglass from PFT to UST, double wall EnviroFlex piping from PFT to the piping transition sump, and double wall welded 304 stainless steel from the sump to the RDS mounted on the rooftop next to the helicopter landing pad.

Ensat’s scope was expanded to include an 8,000-gallon ACT-100 steel underground oil water separator with deadman system, installed adjacent to the Jet Fuel UST.

Extensive coordination between several firms on the Design Team, general contractor, mechanical contractor, electrical contractor, and the Owner has been required from Day One of this project. Anticipated completion is October 2003.
