Piper Alpha was an oil platform located in the North Sea about 120 miles (190 km) north-east of Aberdeen, Scotland. It was operated by Occidental Petroleum and began production in December 1976, initially as an oil-only platform, but later converted to add gas production. Piper Alpha exploded and collapsed under the effect of sustained gas jet fires in the night between 6 and 7 July 1988, killing 1.

Because the platform was completely destroyed, and many of those involved died, analysis of events can only suggest a possible chain of events based on known facts. Some witnesses to the events question th.

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). .
