Regional Energy Access Expansion Project

Michels Trenchless, Inc. performed a Direct Pipe® installation of approximately 1,348 linear feet of 42-inch API 5L-X70 steel sacrificial casing, followed by the installation of a 30-inch API 5L-X70 steel pipeline. This work was conducted as part of a broader mainline pipeline construction project. The crossing was executed using trenchless technology to minimize surface disruption, with the Direct Pipe® technology being employed for the installation of the sacrificial casing. Due to stringent permit requirements, minimal lubrication was used during the casing installation, which presented challenges during the removal of the sacrificial pipe and the installation of the product pipe. HDD technology was then utilized to assist with casing removal and facilitate the installation of the 30-inch pipeline, with the DP thruster unit pushing from the entry side and the HDD rig providing pull support from the exit side. The entire process was carried out at a complex eight-degree slope for the entry, transitioning to a 12-degree exit angle as the pipeline passed under the Susquehanna River. 

The successful installation of the 30-inch product pipeline contributes to the regional energy infrastructure, ensuring more reliable transportation of energy resources to meet growing demand. Furthermore, this project demonstrates Michels’ commitment to innovation and sustainability, ensuring that development can proceed while minimizing environmental impact.
