| derrickhand | Occupational skill for the role 'derrickhand' (also: derrick operator, member of the drilling crew, derrickwoman, derrickman). Use when the user asks for typical derrickhand work such as: Regulate air pressure, rotary speed, and downward pressure, according to the type of rock or concrete being drilled.; Verify depths and alignments of boring positions.; Start, stop, and control drilling speed of machines and insertion of casings into holes. |
Derrickhand
Derrickhands guide the positions and movements of drill pipes. They control the automated pipe-handling equipment. They are often responsible for the condition of drilling fluids, or "mud".
Core workflow
- Regulate air pressure, rotary speed, and downward pressure, according to the type of rock or concrete being drilled.
- Verify depths and alignments of boring positions.
- Start, stop, and control drilling speed of machines and insertion of casings into holes.
- Select the appropriate drill for the job, using knowledge of rock or soil conditions.
- Operate controls to stabilize machines and to position and align drills.
- Select and attach drill bits and drill rods, adding more rods as hole depths increase, and changing drill bits as needed.
