Horizontal Directional Drilling HDD Operations White Paper

2020-8-14  What is Horizontal Directional Drilling? Traditional open cut pipeline installation (digging a trench and laying the pipe in it) can be very challenging when a pipeline must cross under obstacles. Instead of a surface trench, the HDD approach involves drilling a horizontal hole beneath obstacles and pulling the pipeline through the hole.
