Course overview

What is the HDD method for pipeline? How big of a pipe can you directional bore?

In the realm of Horizontal Directional Drilling (HDD), a pivotal aspect of design lies in crafting the optimal approach and bore path profile for the crossing. This webinar offers comprehensive training on the selection of the right HDD design approach and the meticulous design of the bore path. Key considerations encompass precision, surface and subsurface conditions, and their implications on HDD design.

Furthermore, the webinar delves into the technical intricacies of product pipe stress analysis, offering insights and practical knowledge. Through engaging design calculations and illustrative examples, participants will gain a profound understanding of this critical aspect.

To provide a holistic perspective, the course culminates in an in-depth exploration of HDD design through a class project, utilizing relevant HDDPT modules. Gain hands-on experience and apply the acquired knowledge to real-world scenarios.

Our live-virtual trainings are conducted in a real-time question and answer classroom format. You may ask questions or comment throughout either verbally or in writing.
