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] NOV's two main predecessors, Oilwell Supply and National Supply, were founded in 1862 and 1893, respectively. These two companies manufactured and distributed pumps and derricks. In 1930, acquired Oilwell Supply. In 1958, merged with National Supply. In 1987, National Supply merged with USS Oilwell to become "National Oilwell". Varco was founded as Abegg and Reinhold Company by Walter Abegg and Baldwin Reinhold i.
[pdf] The XLE4 is based on the design of the three existing rigs, but will have several modifications and incorporate enhanced features to improve efficiency, safety and onboard logistics that will make it the largest and most advanced jack-up rig in the world. These include dual pipe handling to maximise uptime and. .
In the North Sea, the Maersk drillship Gallant has drilled to an even greater depth. In August, the company reported that at a total depth of 5,941 metres, it had beaten the record for. .
Maersk Drilling’s chief commercial officer Ana Zambelli says the new drilling technology is the differentiating factor for customers when oil prices are so low. Offshore installation manager Craig Fraser adds: “It’s a demanding industry. Clients want performance. .
