Unlatching pipe
A derrickhand or derrickman is the person who sits atop the derrick on a drilling rig.[1] Though the exact duties vary from rig to rig, they almost always report directly to the driller.[2] Their job is to guide the stands of the drill pipe into the fingers at the top of the derrick. Other duties might include monitoring pH and calcium levels, viscosity and the mud weight (density), adding chemicals and oil based fluids, and being responsible for the shale shakers and mud pump.
