One of my clients, Spartan Tank & Trailer, is building a trailer to be used on a frat site in the oilfields. I have been helping them with the wiring. It's a very interesting concept -
(Frac site definition - Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well.)
30kwatt, 3-phase, 208/120v generator, lighting system, computer system, x2 pumps, x2 air compressors, mini-split A/C unit. The idea is that this is a standalone fuel pump trailer. It was designed with 24 hose reels, 2 pumps, and a computer system to control everything. Apparently, this trailer will be parked at a frac site and will consistently feed fuel to each machine/piece of equipment on the site. Oh, did I mention, it has a 7000 gallon fuel tank??
We have been working on this trailer off and on for several months now, and here is some of our progress -
All we have left to do is power it up, test pump rotation, and test operation of generator. Then we have to make an instructional video on how to use all the different functions and features and we're done!
