![]() ![]() K3 Directional Drilling upgraded to the latest D100x140 S3 model and added an R250C to complete the work. Spaced about 10 feet (3 m) apart, each bore is roughly 1,100 feet (335.3 m) long and 60 feet to 80 feet (18.3 m – 24.4 m) deep through some rock formations. The job called for two 18-inch (45.7-cm) water mains to be installed to run water to the bridge and a 16-inch (40.6-cm) reclaiming line to help circulate the water. crew used their D100x140 S3 and R250C to install new water lines to the water bridge at Walt Disney World Resort, where ferry boats float over buses. The footage Eastern Utilities could do in a day speaks volumes to the efficiency of the Vermeer D100x140 S3. The R250C, though, kept pace with the drill crews’ needs the whole time.įrom start to finish, Eastern Utilities completed 22 drill shots, most in excess of 800 feet (243.8 m), in less than two months, with a total of 35 drilling days. It would have taken more than 10 large vacuum excavator trucks on a project of this size and scope, pumping and dumping, to keep pace with the drill. There aren’t many fluid disposal sites in the Long Island area, and those that exist can be costly. The R250C supplied enough cleaned drilling fluid to maximize production. Well over one million gallons (3.8 million L) of fluid were used on the 18,400-foot (5,608.3-m) project with a 125-gallon per minute (473.2-L/min) pumping average. Each drill path was bored to 18 inches or 20 inches (45.7 or 50.8 cm), depending on whether a double or triple 6-inch (15.2-cm) conduit bundle was being installed. The Eastern Utilities drill crew achieved an average bore speed of 25 feet per minute (7.6 m/min) on the 8-inch (20.3-cm) pilot bore, 10 feet per minute (3 m/min) on the pre-ream pass and 30 feet per minute (9.1 m/min) on the ream and pipe pullback. Using a D100x140 S3, each day, the drill crew walked the machine into position, aligned the rod loading boom truck and tanker trailers, drilled out 800 feet (243.8 m), made multiple reamer passes and then pulled the conduit in on the fourth pass.Įach day, they were drilling 3,200 feet (975.4 m) of rod in only eight hours, which included swapping out rod baskets several times every pass. That meant each bore diameter needed to be between 18 inches and 20 inches (45.7 cm and 50.8 cm) to accommodate dual or triple 6-inch (15.2-cm) conduit bundles. Maintenance holes were spaced out to 800 feet (243.8 m) on this project, the owner’s preference to do them in one pass to minimize disruptions. Eastern UtilitiesĬontinuous bore shots of 800 feet (243.8 m) in the sandy soils of Long Island, New York, and all the machinery needed to be taken off the road at the end of each day - these were just a few of the challenges Eastern Utilities Services LLC faced on an 18,400-foot (5,608.3-m) electrical transmission conduit project on Long Island. ![]() Here are just a handful of examples of how crews use this combo to make quick work of challenging HDD projects. In fact, many contractors are calling the D100x140 S3 and the R250C some of the hardest working machines in their fleet. ![]() It also offers plenty of cleaning performance with its scaled double-deck with 56 square feet (2.9 m 2) of total screen surface area. The R250C self-contained mud-recycling system helps minimize the time and cost of transporting water to the jobsite with a tank capacity of 3,690 gallons (13,968.2 L). The D100x140 S3 delivers 275 horsepower (205 kW), 14,000 foot-pounds (18,981.5 Nm) of torque, rotational speeds up to 203 rpm and a thrust/pullback of 100,000 pounds (444.8 kN). Why? The two machines working together provide a solution for HDD installations engineered for drills in the 100,000-pound class. Whether installing smaller-diameter utilities at long distances or in challenging ground conditions, or you need a go-to drill for larger-diameter electric, water, oil and gas pipeline work, you should consider using the mid-size Vermeer D100x140 S3 and R250C. ![]()
