Derrickman nature of work
The derrickman is one of the drill rig crew members who gets his name from the fact that
during trips he works on a platform attached to the derrick or mast, typically 85 ft (26 m) above the drill rig
On small land drilling crews, the derrickman is second in rank to the driller. Larger offshore crews may have an
assistant driller between the derrickman and the driller.
In a typical trip out of the hole (TOH), the derrickman wears a special derrickman safety harness that enables
him to lean out from the work platform (called the monkeyboard) to reach the drillpipe in the center of the derrick
or mast, throw a line around the pipe and pull it back into its storage location (the fingerboards) until it is
time to run the pipe back into the well. In an emergency, the derrickman can quickly reach the ground by an escape
line often called the Geronimo line.
His other job is to handle the mud-processing area during periods of circulation. The derrickman measures mud
density and conducts the viscosity test on a regular basis. The derrickman reports to the toolpusher during periods
of circulation, but is instructed in detail by the mud engineer on what to add to the mud, how fast and how
Derrickmen are employed by drilling and well service contractors and by petroleum producing companies.
Derrickman work conditions
The derrickman usually work long hours in all weather conditions on extended roster systems, usually as member
of a crew. In terms of skill, physical exertion and perceived danger, a derrickman has one of the most physically
demanding jobs on the drill rig crew.
