Horizontal directional drilling (HDD); Dealing with the challenges

Horizontal directional drilling (HDD) is one of the fastest growing techniques for trenchless installation of pipelines. On one hand they provide a logical alternative when cables and/or pipes need to cross dikes, wetlands, rivers and other structures that need to remain intact during construction. On the other hand HDD techniques minimize the impact of construction activities in densely populated and economical sensitive areas.

In the Netherlands HDD has been used on a large scale since the eighties. Considering the soft soil conditions in the Netherlands, a lot of experience has been gained in minimizing risks and as a result construction delays. Being able to identify risks on forehand giving different circumstances, allows the application of ideal equipment and methods.

During this two-day course participants will learn to master the design of HDD crossings while considering the risks involved. This will help participants to choose the appropriate equipment and materials from the large variety that is available today. During this course the state-of-the-art developments in HDD technology are considered.
