Calumet River Direct Pipe

Scope

Michels successfully installed 1,530 feet of 36-inch diameter steel pipeline underneath of the Calumet River just south of Chicago, IL.

In 1959, the Calumet #3 transmission line was constructed to provide a natural gas supply to the industrial and residential customers populating the growing city at the time. By 2013, the pipeline needed to be updated and retrofitted through a number of identified project locations. Even though horizontal directional drilling (HDD) is often the trenchless technology of choice, based on soil boring data acquired during the project planning phase, the Direct Pipe installation method was determined to be the best approach for our customer’s project.

Direct Pipe combines a pipe thruster and tunneling machine, allowing a borehole to be created and pre-fabricated pipeline inserted in one continuous step. Originally introduced in Germany, Michels is one of the only Direct Pipe contractors that has employed Direct Pipe on both US and Canada projects.

Michels is one of the largest horizontal directional drilling contractors in North America yet for this natural gas pipeline replacement project, we used Direct Pipe technology to execute the challenging trenchless installation. The project included a 9.32-degree horizontal curve implemented at a 3,000-foot radius and 7-degree entry and exit angles.
