The Horizontal Directional Drilling (HDD) construction method is an innovative and effective trenchless technique for installing different types of services.
This approach is becoming increasingly popular as it greatly reduces the amount of disruption at the surface, which is a vital factor for the construction of storage tanks like Liquid Natural Gas (LNG) storage facilities and silos.
The technique involves the drilling of a pilot hole that is steered along the desired trajectory; once completed, the hole is enlarged to enable the service pipeline to be pulled back through it.
