2009 Large Directional Drilling Rig Census
When horizontal directional drilling (HDD) professionals discuss the size of an HDD rig, they usually refer to the maximum pullback force the unit can develop.
The most common industry standard for a large directional drilling unit is defined as having a minimum of 100,000 pounds of pullback force. In addition to pullback, the most common specifications used to categorize HDD equipment are rotary torque of drill stem, rotation speed and the size of drill pipe.
Underground Construction’s 2009 census of large horizontal directional drilling contractors is an effective tool when selecting the right size drill rig to fit specific project needs in managing a successful HDD operation.
Years of experience and the best in modern technology enable the contractors listed to effectively perform projects that are within the listed range of their specific units.
