Keeping a Fracking Sand Depot Facility Lighting System within Budget
A depot for the transportation of fracking sand asked a commercial lighting company to design and install a turnkey solution that was within the scope of its budget.
The facility itself is located at the end of a mile and a half of roadway. It consists of 110,000 square feet of paved work area.
Within the work area, stand several 80-100 foot silos that hold sand used in fracking, a process that extracts natural gas. Several buildings and a paved parking lot are also located at the site, and a small crew runs the operation.
The sand is brought in on rail cars that load it into the silos. The roadway that runs through the depot loops back on itself, allowing trucks to line up single file, enter the facility, load the sand into trailers, and then exit in the direction they entered.
A fracking sand depot facility lighting system had already been developed. However, the system was designed with equipment that was way over budget.
Costly LED lights had been planned for the roadway lighting system, and there were twice as many industrial area lighting poles as were needed. Also, the foot candle average in the work area was determined to be twice as high as necessary.
The general contractor for construction requested that the commercial lighting design firm design a more cost effective fracking sand depot facility lighting system within the following parameters:
1. Foot candle average along the roadway should be one tenth lumens per foot.
2. Foot candle average in the work area should be 5 lumens per foot.
3. Reduce the number of industrial area lighting poles by incorporating a more efficient light distribution pattern into the design.
The commercial lighting design company would also need to relocate three industrial area lighting poles that had been specified in the original proposal. These proposed locations were far too close to the railroad tracks. They would have to be moved to the interior without compromising the level of light.
The fracking sand depot facility lighting system consisted of pulse start metal halide fixtures for roadway lighting and industrial area lighting. Full cutoff fixtures were mounted on thirty-eight poles measuring 35 feet in height were mounted on concrete bases that stand 3 feet off the ground. 400W fixtures were chosen for the roadway, and 1000W fixtures were used to light the parking lot and the paved work area.
These fixtures use vertical lamps that are made in the USA . They are from wind, sand, and high heat by a powder coated finish.
The pulse start metal halide lamps in our fracking sand depot facility lighting system are energy efficient. This gives them a longer lamp life than standard metal halide and high pressure sodium lights and minimizes repair and replacement costs.
1. Foot candle average along the roadway was redesigned to the industry standard 1/10 lumen per foot. The 400W fixtures used were sufficiently energy efficient for this task, and they were far more cost effective than the originally proposed, LED lights.
2. As previously noted, the originally proposed fracking sand depot facility lighting system had called for an excessive10 lumens per foot.
By reducing this to 5 lumens per foot, the commercial lighting design company was able to produce a high level of light with clear visibility using only half as many 1000W fixtures.
Fixture reflector type was highly instrumental to keeping the fracking sand depot facility lighting system within budget. Poles were placed in accordance with the pattern of light output emitted by each fixture.
1. Poles along the roadway were fitted with type 3 reflectors that yield an excellent throw on both sides of fixtures. This produces an elongated lighting pattern conducive to roadway lighting.
2. Poles used around the perimeter of the work area were fitted with type 4 reflectors that yield a forward throw that avoids wasting light behind the pole
3. The three industrial area lights that were moved to the interior were fitted with type 5 reflectors. These reflectors emit light in a circular pattern in all directions.
The cost of the industrial area lighting system fell within acceptable parameters of the budget. The commercial lighting design company has since implemented a turnkey solution that involves the digging of 6,000 feet of underground trenching, along with the design and installation of the electrical system. Construction of pole bases, installation of lighting poles, and installation and testing of light fixtures was also part of the project.
