Just What is Rig Mobility for Drillbotics?

 

In the guidelines, rig mobility is one of the criteria being scored by the judges.  What exactly is rig mobility? Well, that is somewhat arbitrary, based on each judges view of what is needed.  Having a rig that is small enough to fit through a doorway is obvious.  If the winning team has a rig that cannot be transported into the exhibit hall at the Drilling Conference it certainly is not very mobile.  But having wheels and perhaps folding components is not enough.

Next year, we will include in the Guidelines more detail.  For example, what are the overall dimensions when rigged up?  Most conference venues limit the height to 2.5 or perhaps 3.0 meters.  SPE gives us a booth that will be approximately 10 x 10 ft square.  But if you want to operate the rig, think about what power supplies will be available.  If you are air drilling, where will you find an air supply. Compressors are too noisy for the exhibit floor.  If you use more than one voltage, transformers must be provided or rented.  An open loop mud system will present problems.  So we assume that you may not be able to actually drill, but can you at least make things turn so that you can show your audience how fantastic your rig is?  In the future, we will ask you to briefly describe how you plan to exhibit your rig.

Thinking about  transportation to the conference, we will also ask you to consider estimating the air or road freight costs.  Freight providers compute their fee using the chargeable weight of the object being shipped.  This is based on two factors: weight and volume.

The Chargeable Weight of Air Freight shipments are calculated as the Actual Weight (Gross Weight) or the Volumetric (also called Volume or Dimensional) Weight of the shipment, whichever is the greater. This uses an estimated weight that is calculated based on the dimensions (length, width and height) of a package (shipments are always shown in the order of L x W x H). Typically, large items with a light overall weight take up more space on an aircraft than a small, heavy item. That’s why the airlines charge according to Chargeable Weight.

For airlines, multiply the length by the width by the height (L x W x H) in inches to obtain the cubic inches, then:

  • To obtain the dimensional weight in pounds using inches, divide the cubic inch result by 166
  • To obtain the dimensional weight in kilograms using inches, divide the cubic inch result by 366
  • Using Dimensions in Centimeters: To obtain the dimensional weight in kilograms using centimeters, multiply the length by the width by the height (L x W x H) in centimeters and divide the result by 6000
