Never Settle - Importance of Settlement Analysis and Monitoring in Trenchless Design & Construction4
A major concern among third party owners when trenchless
projects are constructed near their infrastructure is settlement.
Settlement of the surface can have detrimental effects on
roads, railways, buildings, pipelines or other facilities. In the past
trenchless installation methods have been the preferred method
of these third party owners to cross beneath their infrastructure
because of the less intrusive nature of the construction.

Installing a pipeline crossing beneath a sensitive resource
over a length exceeding 15,000 feet may seem like a
dismaying endeavor for the majority of companies. Even in
ideal conditions, drilling over 15,000 feet of any diameter hole
would be a formidable challenge for even the most experienced
HDD driller.

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.
