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:
The mast is assembled horizontally at ground level and pinned onto the substructure. Hydraulic cylinders or the drawworks is used along with an A-frame support to raise the mast to working position.
Check out this mast on some of our standard rigs: Ideal, Ideal Box, Ideal Prime, Drake, Smart Box, SEAM, European, Mono-Transit, Middle East; and on our custom terrain rigs: Desert, Heli and Arctic.
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.
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.
