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).

The key criteria for topsides layout are summarized in the figure below. The ultimate goal of any layout development is to minimize the risk in achieving the projective objectives and minimizing the risk to the facilities throughout its operating life. The design development process should incorporate the hazard. .
Final orientation of an offshore facility is largely governed by the prevailing wind direction, sea current characteristics, pipeline approach to the facility, service vessels, jack-up rigs, construction barges and drilling rig limitations. The orientation of the facility should. .
The layout of the offshore facility should ensure safe and unhindered access for the following operations: 1. Access to frequently operated manual valves. 2. Access to take field mounted instrument readings. 3. Access to emergency shutdown valves and. .
Safety is one of the key drivers of offshore plant layout. Since offshore facilities tend to be confined, the effect of fire and explosion in one unit. .
Use of grating in offshore facility will promote natural ventilation and minimize the accumulation of vapours and potential overpressure in the.
