Development of a Framework for Risk Assessment for Horizontal Directional Drilling Applications

Horizontal directional drilling (HDD) is a steerable trenchless construction method adapted in the
1970’s from the horizontal oil well drilling technology. HDD has become a very successful worldwide
technology for trenchless utility and pipeline installations becoming an annual multi-billion dollar
industry across five continents. The HDD process involves considerable risks based on many hazards
and uncertainties including risk resulting from unknown ground conditions, construction risks, and
environmental concerns. In response to the critical demand from industry to address these HDD
issues, the University of Alberta and The Crossing Company (TCC) established a collaborative
research partnership. The proposed research will focus on developing a risk assessment framework
addressing the geotechnical and construction risks involved with HDD to develop risk mitigation
strategy guidelines and predictive model development to enable trenchless technology stakeholders to
appropriately and successfully plan and construct HDD installations.
