#Horizontal directional drilling contractors install#
Michels was contracted to install two new sections of a 10-inch pipeline beneath the Anchor River as critical links to complete an expansion project. Michels redesigned and used horizontal directional drilling to complete a 2,384-foot crossing of 12-inch STW pipe under the Missouri River. Michels crews worked 24 hours/day to complete six tie-in welds and the HDD pipe installation once the ramps were closed and had the ramps reopened within 10 days. Michels installed a 4,000-foot land-to-land and a 1,600-foot water-to-land installation of 16-inch pipe. To minimize disturbances to the area, the bore path extended 268 feet below the bottom of the Lake Sakakawea Reservoir in the Missouri River.

In addition to our land-borne HDD experience, we have also completed many marine crossings - both land-to-water and water-to-water. Since the early 2000s, we've been at the forefront of pilot hole intersects, an HDD method that allows us to essentially double the length of a borehole by drilling from each side of a project and meeting at a pre-designated point near the middle.Īs an HDD contractor, Michels has successfully completed crossings in all 50 states, Canada, along the U.S.-Canada and U.S.-Mexico borders, and internationally. In the hands of our skilled operators, these machines are capable of placing pipe up to 60 inches in diameter to distances of more than 15,000 feet. Our fleet includes many sizes of rigs, including our largest with drilling thrust/pulling power up to 1.8 million pounds. We've become a world leader in directional drilling companies by design, building and mastering the use of powerful rigs to place utility lines substantially deeper than conventional trench construction, providing significant cover for crossings under waterways, existing utilities, and underground structures.
Horizontal directional drilling, or HDD, is a versatile trenchless pipe installation technique we have been mastering since we first performed it in 1988. We can bore from 3/4 inch to 12 inches in diameter.Maximum distance and precision, minimal disruptions Finally, the pipe or conduit is placed in the enlarged hole.
The second stage enlarges the hole by passing a larger cutting tool knows as the reamer. In the first stage, a pilot hole is drilled on the pre-determined path. This method comprises a three-stage process. Directional boring is safe, fast, environmentally friendly, and suitable for many soil conditions. Also, the HDD technique is used when conventional excavation is not practical or when minimal surface disturbance is required. It reduces surface disturbance and minimizes impact on traffic and residents. This technology allows us to install pipe or conduit under roads, rivers, and existing structures without disrupting the surface.ĭirectional boring is useful because it makes boring underground holes possible without disturbing the surface. Horizontal Directional Drilling (HDD) is a minimal impact trenchless technology for installing pipes, conduits, and cables in underground bore-path construction.
