The HDD method: Minimizing the impact
Dave, an Engineering and Construction Manager on Enbridge’s Line 3 replacement, explains the HDD (Horizontal Directional Drilling) method. HDD operations in the pipeline industry are used for large rivers or other sensitive crossings by drilling well under the waterway or designated area—usually 1,000 feet or more in length—to minimize impacts to the environment and the community. “You see (HDDs) in a lot of different industries. This is the super-sized version of that,” says Dave.
