Oilfield drilling rig

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]

Workover rig drawworks connect drill line

The drawworks reels in and reels out the drilling line. The drilling line is connected to the traveling block and hook which connect to the drill string. The drill string runs over the crown block and setup like a block and tackle pulley system. [pdf]

Drilling rig brake

The main brake of a drilling rig is the mechanical band brake or the hydraulic/ mechanical disk brake system. As the name implies, the primary method of stopping the draw-works drum is by the use of the main brake. It is, therefore, essential. . In conclusion, Figure 11 shows draw-works brakes’ speed/torque characteristics. 1. Friction brakes may have very high static friction, but with a limitation of dynamic friction. 2. Hydraulic. . Auxiliary brakes control the descent rate of the traveling block carrying a heavy load. They serve to: 1. Ensure that the load comes down slowly and smoothly. 2. Reduce the wear of. The main brake of a drilling rig is the mechanical band brake or the hydraulic/ mechanical disk brake system. As the name implies, the primary method of stopping the draw-works drum is by the use of the main brake. [pdf]
