Where it is impractical or inefficient to bring the equipment to be fuelled to a fuel island, it is usual for the fuel to be brought to the equipment using a fuel bowser. In the past, this has reduced fuel security or reliance on written fuelling information from the browser driver. However, because the jigsaw system uses the mobile data network, refuelling from a browser is now as secure as on a static fuel site.
Typically, the fuller has to park the fuel bowser adjacent to the equipment to be fuelled, then reel the hose to the fuelling point. Whether the fueller ID’s the vehicle first, pulls out a charged hose, inserts the nozzle, and walks back to the fuel terminal, there is a much-increased possibility that fuel will be spilt.
