Driving the Vehicle
When driving the vehicle, the operator should always be conscious of things that could cause the vehicle
to disengage from the driving surface, either by drastically increasing magnet gap or overcoming the
magnetic force entirely. These include the following:
•
Welds or obstacles that are too large for the vehicle
•
Inward bulges or curves that increase magnet distance
•
Sheathing or coatings that increase magnet distance
•
Tensioning the tether at a large angle from the driving surface (approaching perpendicularity)
Always try to minimize the above risks to avoid system damage.
Inspection Guidelines
The objective of an inspection is to obtain a recording of video and other data for review by the customer
or pipe owner. If a recording is lost, fails to record, or is of poor quality the inspection will likely have to be
re-
done at the operator’s expense. Therefore, it is in the operator’s best interest to verify vehicle
operation, video quality and recorder function before beginning each inspection.
A set of video overlay comments and data are usually required depending on the contract or client. Initial
comments will usually include the location, pipe number and date. During the inspection the contractor
may require certain pipe features or faults to be pointed out along with the distance from the pipe entry.
Conduct a complete inspection of pipe features and faults. For any feature or situation of interest, stop
the vehicle and make a complete video survey using the continuous pan feature of the camera.
Ultimately, the inspection is conducted for the benefit of the client who is reviewing the footage later on.
