(Video Only. No PDH available)

This course delves into the crucial aspect of HDD design: assessing the technical feasibility of crossing obstacles through HDD methods.

The focus lies in determining whether the proposed crossing can be successfully implemented using current tools and techniques. This feasibility is established by comparing it to past installations. Numerous factors are involved in evaluating an HDD project's feasibility, with the initial site survey being fundamental. This survey encompasses both surface and limited subsurface investigations.

The webinar will cover essential tasks within a site survey, including surface and subsurface concerns. This includes understanding how natural and man-made features affect the crossing's configuration, as well as how subsurface conditions impact construction phases. Critical characteristics like soil types, stratification, groundwater conditions, topography, and human activities will be addressed.

Moreover, the course will discuss the evaluation of drilling fluid flow risk due to hydro fracture, considering the environmental impact. Real-world project feasibility studies and reports will also be explored to provide practical insights.

Content SME for Horizontal Directional Drilling
Mr. 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.
