Rigging up is the placement and assembly of the rig itself, and preparing it for drilling. This phase involves the use of cranes, trucks, forklifts, and other heavy machinery to position equipment for assembly, offering plenty of opportunities for workers to be hit by moving vehicles or swinging equipment. Assembling the rig. .
Once the rig is built, it’s time for drilling ahead. In addition to the constant risk of being struck by tongs, spinning chain, or pipe, drilling workers also face the possibility of flash fire. Sixteen percent of all oil and gas fatalities are the result of exposure to flash. .
Maintenance is a constant activity on any drilling rig. Inspecting, adjusting, and servicing equipment on every part of the rig brings maintenance workers into contact with all kinds. .
Eventually, the bit or some other piece of the drill string is going to need to be replaced. Removing or replacing pipe from the well is known as tripping, runs the risk of exposing workers. .
Casing is used to line the well hole with pipe longer and bigger in diameter than the drill pipe. Casing operations happen periodically during drilling, with hazards similar to that of.

Drilling derricks and Rig Masts consist of a steel framework with a square or rectangular cross-section. Their purpose is to support the hoisting equipment and rack the tubulars while tripping pipe. The number of joints in a stand (single-double-triple) that the rig can pull is dependent on the height of the derrick. .
The Drawworks is one of the most important components of the drilling rig (types of drilling rigs). The unit supplies the hoisting power, the. .
The Crown Blockas a drilling rig component is a fixed set of pulleys (called sheaves) located at the top of the derrick or mast, where the drilling line is threaded. The companion blocks to these pulleys are the traveling blocks. By using two sets of blocks in this fashion,. .
The Traveling Blockis a set of sheaves (pulleys) that move up and down in the derrick. The drilling line is threaded (reeved) over the. .
Attached to the bottom of the traveling blocks, the hook is required to hang the swivel and rig kelly(for drilling) and the elevator bales (for tripping pipe and casing).
[pdf] This article lists the main components of a onshore . rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but typically includes at least some of the items listed below.
