The objective of the Differential Impedance Obstacle Device project is to develop a tool that can be coupled with a pipeline drill rig to detect pipeline obstacles in the drill path. The final deliverable is a device that can be commercialized. GTI will conduct a series of in-ground tests to prove that the DIOD can detect obstacles of at least three different materials (plastic, ceramic and metal) in at least three different soil materials (loam, sandy soil, and third type of soil) and demonstrate that the sensor is robust enough to withstand HDD conditions.
The objective of the Differential Impedance Obstacle Detection project is to develop a sensor that can be integrated into the head of a horizontal directional drill (HDD) to detect obstacles in the drill path. The final deliverable is a prototype device that can be commercialized. The form factor of the prototype must be such as to minimally impact the design of commercial drill heads. GTI will conduct a series of in-ground tests to prove that the DIOD can detect obstacles of at least three different materials (plastic, ceramic and metal) in at least three different soil materials (loam, sandy soil, and clayey-silt) and demonstrate that the sensor is robust enough to withstand HDD operating conditions.
