Trenchless Pipeline Installation

Building the World’s Energy Lifeline


Trenchless pipeline installation refers to a group of techniques for installing pipelines underground without the need for extensive excavation or trenching. These techniques are often used when traditional excavation and trenching methods are not practical or are too expensive and is beneficial in urban or environmentally sensitive areas where digging trenches may not be feasible or desirable. Trenchless pipeline installation is a method of installing pipelines without the need for extensive excavation, offering a range of benefits over traditional trench-based methods.

Environmental benefits

Here are some of the key benefits of trenchless pipeline installation:

Reduced Disruption

Trenchless pipeline installation can significantly reduce the amount of excavation and disruption required at the installation site, minimizing damage to infrastructure, traffic, and the environment.


Trenchless pipeline installation can be more cost-effective than traditional excavation methods, as it reduces the need for heavy equipment and labor, and can shorten project timelines.

Environmental Benefits

Trenchless pipeline installation can reduce the environmental impact of pipeline construction, as it minimizes soil disturbance, reduces the risk of soil erosion, and avoids damage to trees and other vegetation.

Improved Safety

Trenchless pipeline installation can enhance safety by minimizing the need for excavation and reducing the risk of accidents and injuries associated with heavy equipment and excavation work.

Improved Aesthetics

Trenchless pipeline installation can improve the aesthetics of the installation site, as it reduces the amount of visible excavation and disruption.

Access to Sensitive Areas

Trenchless pipeline installation can provide access to sensitive areas where traditional excavation methods may not be feasible, such as under roads, buildings, and waterways.

Overall, trenchless pipeline installation offers a range of benefits over traditional excavation methods, including reduced disruption, cost-effectiveness, environmental benefits, improved safety, improved aesthetics, and access to sensitive areas, making it a preferred method for pipeline installation in many situations.


Preserve and conserve

However, there are also some challenges associated with trenchless pipeline installation. Here are some of the key challenges faced in trenchless pipeline installation:

Overall, trenchless pipeline installation can be a beneficial method for installing pipelines in certain locations, but it also requires specialized equipment, expertise, and careful planning to overcome the challenges associated with the method.
Equipment and Technology

Trenchless pipeline installation requires specialized equipment and technology, which can be expensive and may not be readily available in all locations. Additionally, the complexity of the equipment and technology may require highly trained operators and technicians to ensure safe and effective installation.

Ground Conditions

The success of trenchless pipeline installation depends on the ground conditions at the installation site. Ground conditions such as soil type, rock density, and groundwater levels can affect the ability to install the pipeline using trenchless methods.

Environmental Concerns

Trenchless pipeline installation must comply with strict environmental regulations to avoid damaging sensitive habitats or water sources. Additionally, the use of trenchless methods can pose a risk of soil contamination if leaks or other issues occur during installation.

Accuracy of Installation

Trenchless pipeline installation requires precise drilling and placement of the pipeline to ensure it is properly installed and aligned. Any errors in the installation process can result in leaks, collapses, or other problems.

Limited Access

Trenchless pipeline installation can be challenging in locations where access is limited, such as densely populated urban areas or areas with limited space for equipment and machinery.

Ace has been able to successfully overcome the above challenges, and currently executes trenchless installations in the following methods:

Horizontal directional drilling (HDD)

HDD is a technique for installing pipelines under roads, rivers, or other obstacles without disturbing the surface. A drill rig is used to bore a tunnel underground, and the pipeline is pulled through the tunnel from a starting point to an exit point.


Microtunneling is similar to HDD, but it is typically used for smaller diameter pipelines. It involves a remote-controlled tunneling machine that is used to bore a tunnel underground, and the pipeline is installed inside the tunnel.
