Sweet Caroline: HDD Intersect on the Beach
|
|
Recently Dominion Energy needed a project completed in Myrtle Beach, South Carolina. South East Connections was hired as the general contractor to complete Phase 1, which included the installation of a little more than three miles of new 8-in. steel gas line. West Concord, Minnesota-based Ellingson Trenchless was retained to complete the horizontal directional drilling (HDD) work on the project which consisted of three separate HDD bores. The largest bore — a 6,285-ft bore — required extra planning by the ECI team in order to meet project schedule requirements and an elevated risk of inadvertent returns.

Reducing Risks Through Thoughtful HDD Planning and Design
We’ve heard from numerous HDD contractors that many of the HDD designs they receive with bid packages often lack adequate subsurface information, are geometrically infeasible, pose a high risk of inadvertent returns or pose other construction risks.

Enhanced Fluid Recycling Saves HDD Contractors Time and Money
Drilling fluids play a crucial role in the ever-growing HDD industry. These fluids help remove cuttings, stabilize the borehole, and cool, lubricate and extend the life of equipment. But with these benefits comes a drawback: Preparing and disposing of the drilling fluid can be costly.
