For horizontal directional drilling, the first “D” in the acronym HDD is the key to the success of this versatile trenchless technology -- without the directional capability, HDD could never have achieved the impact in utility construction that it has over the last 20-plus years.
As of mid-year, international/offshore reports show planned pipeline miles remain higher than actual pipeline construction mileage. Figures show the international sector accounts for 81,752 miles of crude oil, natural gas and refined products pipelines under construction and planned. Of these, 50,355 miles represent pipelines in the feasibility and front end engineering design phase while 31,215 miles account for pipelines in various phases of construction.
This year the cured-in-place pipe rehabilitation process and Insituform Technologies, the company that created it, celebrate a significant milestone: Insituform’s 40th birthday and the anniversary of the completion of the first commercial CIPP project, a 12-inch sewer.
Preventing damage to underground utility infrastructure is a priority for utility operators and contractors who excavate, drill and bore in areas where there are existing utilities.
