Horizontal Directional Drilling (HDD) Method Pipe Update


The case history will discuss HDD methodology and challenges. With all the benefits of HDD comes the disadvantages especially from pipeline maintenance, corrosion control and integrity management. HDD can impose additional strain on the pipeline during the pull through process and can increase both installation stress and operational stress. HDD installed pipeline crossings are deep and could easily become low points for liquid hold up causing flow issues.

Pipeline installation by Horizontal Directional Drilling (HDD) i.e., trenchless technology, has gained popularity over the last four (4) decades. Sound engineering practices, site conditions, and safety considerations dictate the use of HDD methodology for installing a pipeline segment. HDD is often recommended by regulatory agencies and governmental agencies to avoid contamination, disturbance, and flow interruption of water bodies and especially in environmentally sensitive areas (ESAs). This pipe replacement is an update of the field work, design, pull through installation, type of coatings, inspection, repair, and cathodic protection (CP) testing.
