Since the HDD market has improved considerably over the last two years, new rigs and remanufactured equipment are headed back into the field.

The recent attack on Pearl Harbor was not by an enemy, but by hundreds of friendly construction workers contracted to make it a better place to live and work.
Quite simply, it’s all in the name. Nothing fancy. A descriptor, a colon and the…
The mid-range drill rigs may not be as glamorous as the mini rigs or as spectacular as the maxi rigs, but these machines are considered the workhorses of the horizontal directional drilling (HDD) market.
During the industry boom a few years back, a large number of conduits were installed using horizontal directional drilling (HDD).
It’s like a word problem. You know the one: Two trains on the same track leave at different times, one from the north and one from the south, where will they intersect?
With the recent increase in drill pipe replacement for horizontal directional drilling (HDD) units, now is a good time to review the techniques for proper use and maintenance of the entire drill string.
Cured-in-place pipeline (CIPP) rehabilitation doesn’t spring to mind when talking about NASA. While trips to the moon, life on Mars and rocket science are all in a day’s work, NASA engineers left the CIPP pipe rehabilitation up to crews at U.S. Sewer and Drain Inc. to line the 800-ft, 6-in. diameter clay pipe, which rested partially underneath the NASA Goddard Flight Center.
An HDD machine is a complex combination of mechanical and electronic systems and every directional drilling installation depends on all systems functioning smoothly.
Many contractors are often a victim of what they call the “I’ve done a shot like this before” syndrome. So corners end up getting cut and risk on the job starts from that moment on.
The year 2005 has been a big one for both celebrating the old and welcoming the new at Missouri State University. The university, located in Springfield, Mo., is in the midst of centennial celebrations and in August, dropped the longstanding “Southwest” from its name.
Mud recycling systems in general are fairly simple units to operate but there are some items that need to be watched and maintained in order to to keep your system running smoothly. The following are some suggestions and tips in order to get the most out of you mud recycling system:
In January, a 720-ft, 24-in., DIPS HDPE sanitary sewer line was installed using horizontal directional drilling in Corunna, Ontario, Canada. The entire project took about five days to complete.
Damage prevention is still not an exact science, but locating strategies, tools and processes are helping to reduce the possibility of damage during utility installations.
After several status quo years of work, the maxi rig market appears to have stumbled a bit in 2005 — at least in regard to rig sales — with those in the industry attributing the drop off in large diameter work to a sluggish gas and oil pipeline market.
There are several reasons to be testing the properties of drilling fluid: verification, maintenance and troubleshooting.
Alocating system is an integral part of the HDD process and it represents a substantial investment, ranging from about $10,000 to $20,000.
I am often asked if the viscosity of the drilling fluid affects the efficiency of a positive displacement, single-acting, reciprocating pump.
As most contractors know, the cost and time required to maintain and manage equipment is one of major activities that do not directly generate revenue for the business.
Depth, direction, pitch and roll are the most basic information displayed by all directional drilling receivers. The transmitter inside the drillhead generates a magnetic field, which the receiver interprets as depth and direction.
