Horizontal Directional Drilling (HDD) projects in North America continuously monitor drilling fluid annular pressure during construction. Downhole tooling automatically records "real-time", or "as-built" pressure data. This article gives an insight into recent findings which show how the measured data compares to the industry standard calculated values.

Most commonly overlooked part of any Horizontal Directional Drill (HDD) design is the product pipe pullback support. Design of this part of the process can be just as important as the downhole design for a successful bore-path installation, or even more so.

Direct Pipe InstallationTM (DPI) is becoming a more prominent construction method in the pipeline crossing industry. DPI involves connecting a micro tunnel boring machine to a section of welded pipeline and utilizing a thruster on surface to push the pipeline through the ground while excavation of the soil by the MTBM commences.

The Capital Regional District (CRD) of Victoria, BC is constructing a new wastewater treatment facility. A pipeline was required to cross the Victoria Harbor between Ogden Point and McLoughlin Point. Due to the large volume of marine traffic, a trenchless methodology was chosen.
