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 numbe.

Land rigs are generally either wheel-mounted portable types or a component system that must be moved by trucks and cranes. The drilling floor generally sits on top of a steel substructure that could be 30 feet high or more. A drilling mast (derrick) is attached to and raised above the floor. In general, the deeper. .
One of the Oil Rig Hazards types is the hostile environment. The effects of greater water depths, storms, wave action, and uncertain exploratory data all greatly increase the financial. .
Drill ships are ships specially built and modified to drill in deep water or in operations that are not suitable for semi-submersible rigs. Drill ships are self-propelled and can. .
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.
[pdf] This block is a set of sheaves (pulleys) that move up and down in the derrick. The drilling line is threaded (reeved) over the sheaves on the crown and through the sheaves in the traveling block. This provides a significant mechanical advantage to the drill line, enabling it to lift heavy loads of pipe and casing. The. .
The size of the groove should be the same as the diameter of the drilling line to deliver the proper support. A tiny pulley groove could cause high friction. Furthermore, it can cause. .
Periodic inspections: The Rig Traveling Block, as with all Hoisting equipment, must be inspected according to the manufacturer’s recommendations and API RP 8B or related ISO (International.
