When Australian-based horizontal directional drilling (HDD) specialist Pace Drilling was faced with an increasing demand for larger pipeline installations over longer distances, it needed rigs that could stand up to the tasks. Founded in 2000, the business has gained a reputation for providing cost-effective and quality solutions for its extensive customer base, working tirelessly to meet the challenges each construction job requires.
With the expertise to install underground pipelines for a wide range of utility providers, Pace Drilling can drill bores from as short as 98 feet to as long as 2,297 feet, with pipeline diameters up to 24.8 inches.
Pace Drilling’s director Simon Pace said the company had the expertise and equipment to get jobs done quickly and efficiently not just in New South Wales (NSW), but also interstate if needed.
“Pace Drilling started operations when we saw the demand for trenchless technology for installing underground assets,” he said.
“So I bought my first directional drill rig and began installing underground pipelines all over NSW.
“Our first drill rig purchase was a non-rock capable rig, but in 2008 we purchased our first Ditch Witch all-terrain rig, which gave Pace Drilling the leading edge in rock drilling.”
The business currently owns three Ditch Witch directional drills: the AT32, the AT60 and, most recently, the all-new AT120.
They complement an overall fleet that includes an eight-wheel vacuum truck, a semi vacuum unit, and a range of excavators from 12,000 to 51,800 pounds.
Simon said he loved the Ditch Witch drills for their all-terrain capabilities.
“They give Pace Drilling the advantage over our competitors, being capable of drilling all rock strengths,” he said.
“Plus a key feature is that they have compact small footprints while retaining maximum operating forces.”
The purchase of the AT120 came about as the company expanded along with client requirements for larger diameter pipeline installs. Offering a remarkable 120,000 pounds of pullback force, the AT120 provides confidence and reliability in undertaking even the most challenging projects. Its introduction has significantly enhanced productivity and versatility at Pace Drilling.
The increased inner rod rotational torque has made drilling through rock strata more efficient, especially during pilot shots. Additionally, the machine’s power has streamlined the process of opening larger diameter holes, contributing to a more effective operation overall.
Simon said that Pace Drilling recently faced a demanding project involving a pipeline installation during a night-time shutdown of a heavily trafficked road. Given the limited timeframe and the need for minimal disruption, the AT120 was indispensable. Its robust capabilities ensured the installation was completed smoothly, minimizing impact on the public and the environment.
“The AT120’s rapid carriage speed and dual rod box design have been transformative, setting a new standard in operational efficiency,” he said.
“Additionally, the enhanced inner and outer rod rotational torque has played a critical role in boosting productivity, particularly in challenging drilling conditions.”
Marking a substantial advancement from the AT60, the AT120’s state-of-the-art operator cabin offers an improved, user-friendly experience, significantly enhancing comfort and overall workflow.
Despite its compact size, the AT120 delivers a formidable 120,000 pounds of thrust, meeting the demands of complex projects while minimizing environmental and public impacts. This versatility has expanded Pace Drilling’s project portfolio, allowing the company to undertake larger-scale operations that were previously beyond reach.
Simon said the AT120 also complies with environmental standards, particularly crucial when working with Tier 1 clients.
“The AT120’s Stage V Cummins engine meets these stringent requirements, offering exceptional fuel efficiency and quiet operation — vital attributes in maintaining the company’s commitment to sustainability,” he said.
Pace Drilling operators have praised the AT120 for its quiet and spacious operating station, which offers maximum visibility. These design elements not only improve the user experience but also contribute to safer and more efficient operations.
The VAM (Virtually Assisted Makeup/Breakout) technology has been a game-changer in maximising rod life and expediting rod makeup.
Simon said the most notable benefit has been the increased production rate.
“Completing projects ahead of schedule has enabled us to move on to new assignments more swiftly, translating into tangible cost savings and heightened operational efficiency,” he said.
Simon also applauded service from their dealer, Ditch Witch CEA.
“They’ve always supported their equipment. Pace Drilling has a great relationship with them; we’re now up to our seventh brand-new Ditch Witch in 20 years of operation,” he said.
“We are sure to get more as we are always looking to update and expand to suit our clients’ requirements.”
