Micropiling drilling rigs

Micropiles (mini piles, pin piles, needle piles, and root piles) are deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bars. . Micropiles (mini piles, pin piles, needle piles, and root piles) are deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bars. . The micropile casing generally has a diameter in the range of 3 to 10 inches. Typically, the casing is advanced to the design depth using a drilling technique. Reinforcing steel,. . Comprehensive fleet of rigs and tooling for difficult subsurface conditions and limited access Alleviates quality assurance concerns associated with cast-in-place piling in weak soils Can be combined with other techniques to meet unique or complex project requirements cost-effectively and efficiently . The finished micropile (mini pile) resists compressive, uplift/tension, and lateral loads and is typically load tested following ASTM D 1143 (compressive), ASTM D 3689 (uplift/tension), and ASTM D 3966 (lateral). Capacities vary depending on the micropile size and subsurface profile. Allowable compressive capacities of more than 500 tons have. These drills are primarily used to drill tie-backs using a high-powered percussion head. They can also be equipped to drill using cased methods as required. The units can be mounted on a variety of excavator carriers to suit individual project requirements. [pdf]

National oilwell varco drilling rigs

NOV's two main predecessors, Oilwell Supply and National Supply, were founded in 1862 and 1893, respectively. These two companies manufactured and distributed pumps and derricks. In 1930, acquired Oilwell Supply. In 1958, merged with National Supply. In 1987, National Supply merged with USS Oilwell to become "National Oilwell". Varco was founded as Abegg and Reinhold Company by Walter Abegg and Baldwin Reinhold i. [pdf]

Speculative newbuild drilling rigs

Now, after years of rig market doldrums and rig fleet contraction, the market is experiencing the beginnings of a revival, with rising rates and dwindling availability. In the immediate aftermath of Russia’. [pdf]
