[en] Pipeline installation using horizontal directional drilling method (HDD)

Pipelines crossing rivers, highways, and railways require special consideration that includes details in both design planning and the field installation. One of the methods used for pipelines crossing is the horizontal directional drilling method (HDD). Risks are associated with the HDD installation such as the failure of the pilot boring and reaming, the ground collapsing, and the failure of the pullback process. Construction method based on these risks will be analysed in this paper. Based on the construction method proposed, the quantity of materials, heavy equipment, and workers, and the cost and time are analysed.
