How to discharge petrol from truck tanker in filling station

I had the experience of issues arising in the fillling station concerning incomplete supply of fuel, stolen product by truck drivers and that has raise so many problems in that business. Ddomiscum.com will discuss How to discharge petrol from truck tanker in filling station in detail and I hope this will be of help.

Positioning of the truck

 Assuming the truck has just arrived from the depot, as a station manager or a supervisor, you need to direct the truck to an appropriate position suitable for the proper draining of trucks in your filling station. The position is differ for different filling station, but in all cases it is as to enhance recovery of fuel.

Recording of truck Details

 Immediate after the truck is set at the proper position, the personnel in charge of the discharging process has to record some data of the truck. The information include, but not limited to;

  1. Date and time of arrival
  2. Driver’s name
  3. Truck plate number
  4. Truck tank size
  5. Type of fuel (PMS or AGO or DPK)
  6. Waybill details
  7. Depot ullage details
  8. Truck tank ullage chart

After getting the required information from the truck driver, this information is communicated to the senior authority of the company/filling station to confirm if that is the expected truck and if it carries the desire fuel.

Station Test and Measure

After obtain the information that comes with the truck, there is a great need and in fact it is a must to run your own test and measurement to see if it correspond with the one that came with the driver. Prior to this, there is one term in filling station business in Nigeria called “Asorock”, this is pronounce just like the state house is Nigeria, but it has a different meaning in this line of business. Asorock is an hidden compartment in the truck were drivers store fuel and is invisible to the person discharging the truck. They hide the fuel there and remove it and sell to people on the road side after leaving your station. I believe that you cannot detect Asorock truck, but from my experience, I can teach you how to do that, just contact me.
