A recent project to install more than 6,200 feet of electrical transmission lines in Orange Beach, AL, included multiple challenges, including two intersecting horizontal directional drilling (HDD) pilot holes beneath Wolf Bay inter-coastal waterway channel to complete a single crossing.

On Sunday, April 8, a water main beneath the Boise River near East 52nd Street burst when a dislodged tree floating in the river crashed into it. Immediately, water to supply hundreds of homes in the Plantation neighborhood of Garden City, a suburb of Boise, ID, was disrupted. The city worked quickly to patch the damaged pipe, which was originally installed in the riverbed during the 1970s, but knew a more permanent solution was needed.

Horizontal directional drilling (HDD) as it relates to utility construction usually is dated from the late 1980s when the first compact drill units became commercially available.

Sixty feet below the surface of Sowashee Creek in east Mississippi lies a new section of pipeline – 1,640 feet of 36-inch American ductile iron pipe – installed with little more than a ripple’s impact on the waterway. This section of pipeline marks the longest length of this size ductile iron pipe ever installed using horizontal directional drilling (HDD).

Depending upon where you are located and what niche drives your business, the horizontal directional drilling market for 2012 is a mix of strong, mediocre and stagnant. But where business is good, it is very, very good.

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.

In 2009, integrated systems manufacturer Kem-Tron Technologies barely broke even. Despite a market that’s flat in more ways than one, the company’s president says that as of September 2010 the company’s revenue has already matched the full year totals for 2009, with 30% growth expected by the end of the year. What made the difference?
