The mast is one of the most recognizable parts of a drilling rig. Standing up to 50 metres (164 feet) high, our team uses QT100 advanced steel on our masts to make more space for equipment and reduce the overall weight of the structure.
Not to be confused with four-sided derricks, masts are three-sided structures with an open face.

We mention substructures (a.k.a. “subs”) a lot on the blog, often in relation to moving or walking systems. Located directly over the well, the substructure raises, lowers and supports the rig floor, derrick and other rig floor components like the drawworks.
A common substructure is the slingshot sub. They begin in a folded position and are then unfolded as hydraulic cylinders or winches raise the rig into place. On a slingshot sub, all rig floor components are installed and rigged up with the floor lowered.
You can find slingshot substructures in action on our blog on Rig 38 and our 3,600 HP 700 series.
Sure, you hear the lingo all the time, but have you ever wondered how single, double and triple drilling rigs are named? We have you covered. The derrick on a triple can hold three joints of drill pipe; a double can hold two; and a single can hold one. The taller the derrick, the longer the pipe string it can hold.
Almost 50% of the rigs in Trinidad’s fleet are triples. Check out a few of them here:
What’s your rig word of the day? Let us know in the comments below!
A Derrickhand stands on a rig 90 feet up into the sky. From there, he aligns pipes and directs them from the racking board fingers to the top drive, and vice versa.
The work is intensely physical, and there are always safety concerns, as well.
That’s why Trinidad Drilling is moving to an automated pipe-handling system on the derrick. It’s an exciting new development, both for safety and efficiency, and Trinidad has been testing it for about a year.
With the new system, the Derrickhand is comfortably inside the doghouse, instead of up on the monkeyboard. Instead of manually handling the pipes, he’s controlling them with a machine that carries out multiple functions automatically.
Of all the crew members on a rig, the Derrickhand position is probably the most well known because the Derrickhand climbs the rig’s derrick to work on a platform usually 25 metres above the rig floor.
“I’m the guy who has to put the belt on. Anytime there is something (to be done) up high, I put the belt on and go up the derrick,” said Larince Yewchuk, a Derrickhand on Trinidad Rig 2, referring to the safety harness Trinidad’s hands must wear while working at a height over three metres.
Yewchuk, whose rig operates mostly in southern Alberta, talked to us about what it is like to be a Derrickhand. Continue reading
