Course overview
What are the limitations for HDD?
What are Alignment and Borehole Geometry Considerations? What are constructability and geotechnical Considerations for an HDD pro

The Advanced Horizontal Directional Drilling course is offered as a one-day course that expands on some of the topics covered in our popular HDD course. The advanced course provides advanced coverage of topics such as HDD design, HDD alignment and borehole geometry, HDD constructability, HDD pipeline stress and D/t ratio analysis, HDD cost estimating, subsurface conditions borehole stability, HDD drilling fluids, drilling fluid design and testing, drilling fluid quantity estimating, and drilling fluid monitoring.

This learning opportunity will provide engineers and others working in the HDD industry with advanced coverage of technical information related to HDD design, construction, subsurface conditions and drilling fluids.

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.  

START TIME: 8:00 a.m. (CDT)
END TIME: 4:00 p.m. (CDT)

HDD and Cathodic Protection Design SME, Former Director RK&K, 
David Willoughby has 40 years of experience in engineering, pipeline design, corrosion control, and management in the petroleum and utilities pipeline industry. His experience includes gas transmission and distribution systems, petroleum facilities, and water/sewer pipelines from conception through design, construction and testing, economic evaluation, and project field supervision. Mr. Willoughby has been responsible for the design, permitting, inspection, and construction administration of numerous horizontal directional drills (HDD) on pipeline projects. He is the author of several articles and two books published by McGraw-Hill, The Plastic Piping Handbook (2002) and Horizontal Directional Drilling (2005).

Mr. Willoughby provides HDD training to the pipeline and utility industries. He has presented at the engineering workshop at N.C. Utilities Commission Office of the Pipeline Safety Conference and the Southern Gas Association Annual Conference. Mr. Willoughby’s HDD training is used to provide Professional Development Hours (PDU) for professional engineers in many states, including Texas.
