While there are different types of drilling rigs, these rigs obviously share many similarities since the tasks that they perform are identical. In particular, all modern hydrocarbon rotary rigs contain five main systems. These systems are:
- the Power System
- the Hoisting System
- the Rotary System
- the Circulation System
- the Well Control System (Blowout Prevention System)
These systems are shown in Figure 9.01. In addition, Figure 9.02 shows a more detailed schematic diagram of a rotary table, land rig.
