When to Consider HDD / Trench-less Technology?

Horizontal Directional Drilling or HDD, is a steerable trench-less method of installing underground pipe, conduit, or cable in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area.

Unlike traditional underground installation, HDD does not require open trenches to complete.

What projects are HDD machine suitable for?

- Utility Installation: HDD is frequently used to install various types of underground utilities, including:

Water and Sewer Lines: HDD is used to install water and sewer pipes beneath roads, rivers, and other obstacles, reducing surface disruption and traffic congestion.

Natural Gas Pipelines: Gas pipelines can be installed using HDD to minimize environmental impact and avoid disrupting populated areas.

Telecommunications Cables: HDD is employed to lay fiber optic and other communication cables, ensuring high-speed internet access in urban and rural areas.

Electrical Conduits: Electric power and utility companies use HDD for installing electrical conduits and power lines.

- Oil and Gas Industry: HDD is used in the oil and gas sector for various purposes, including:

Pipeline Crossings: HDD machines are employed to create underground crossings beneath rivers, highways, and other obstacles for oil and gas pipelines.

Installation of Wellbores: HDD can be used for drilling wellbores and conducting underground horizontal drilling for exploration and extraction purposes.

- Environmental Remediation: HDD is used in environmental projects to install remediation systems, such as groundwater monitoring wells, vapor extraction systems, and soil vapor extraction systems, which help mitigate contamination.

- Geothermal Energy: HDD machines are used to drill geothermal boreholes for the extraction of heat from the Earth's crust for renewable energy production.

- Cable and Fiber Optic Installations: In urban and suburban areas, HDD is commonly employed to install underground cables for electrical power, telecommunications, and cable television.

- Municipal Infrastructure: HDD is used for various municipal infrastructure projects, including the installation of stormwater drainage systems, sanitary sewers, and underground conduits for traffic signal and lighting systems.

- Horizontal Well Drilling: HDD can be used in the drilling of horizontal wells for water supply, geothermal heating, or natural gas extraction.

- Renewable Energy: In addition to geothermal energy, HDD can be used in renewable energy projects such as the installation of underground electrical transmission lines for wind farms and solar power plants.

- Subsea Cable Landings: HDD is utilized for bringing subsea communication cables from the ocean floor onto land, connecting them to terrestrial networks.

- Crossings for Railways and Airports: HDD machines are used to create underground crossings for railways and runways, allowing for the installation of utilities without disrupting transportation routes.

- Urban Development: In densely populated urban areas, HDD helps reduce disruptions during construction, making it a preferred choice for utility installations.

Benefits of HDD

HDD is a minimum impact method and especially useful in environmentally sensitive areas such as wetlands, estuaries, rivers, and lakes.

It is a quick and accurate method that enables the operators to accomplish creditable accuracy even when crossings are complicated.

Continuous monitoring and control during the operation allow operators to navigate in constrained spaces between existing utility lines.

Drilling can be carried out at greater depths to bypass existing utilities altogether and requires only one launching shaft at the entry point and one reception shaft at the exit point.
