• Masts

    Bringing together leading rig designers and manufacturers such as DRECOTM, IRI, Continental Emsco and DSI, we have the unique ability to provide necessary solutions for even the most demanding and custom rig applications.
    Description

    Our masts are in service worldwide in every drilling environment. Whether it be dealing with extreme environmental conditions, designing a completely custom rig or just upgrading your current equipment, we have a wide variety of standard mast designs and the experience and engineering power to develop innovative and custom designs.

    Masts for our comprehensive portfolio of standard rig offerings include:

    • Cantilever masts
    • Bootstrap masts
      • The mast is assembled vertically on the rig floor. Once the bottom boot section and top section are in place, the remaining mast sections are inserted into the mast based and safely telescoped sequentially.
    • Telescoping masts
      • The mast is transported horizontally and brought to vertical position during rig-up. Then, the inner sections of the mast embedded in the outer bottom section telescope up to working position.
      • Check out this mast on our Rapid, Vertical Slant, Desert and Arctic Rigs.
