Pipeline Construction

Today marks another milestone for the Wilmot Pipeline construction as the equipment is readied for the pulling of pipeline into the directional drilling bore hole.



A device called a "pull head" is moved into position for welding onto the first section of the pipeline. The pull head will be attached to drill pipe, that is already in the bore hole, and then pulled back through the bore hole.

Back at the bore hole, a reamer and swivel are attached to the drill pipe that runs through the bore hole.

The first section of the pipeline is lifted and moved toward the bore hole.



An "Army" of excavators is required to lift and move the section of pipeline.

With the first section pipeline in position for the "pull back", the second section of pipeline is moved into position for welding to the first section of pipeline.
