Conductor Pipe

Conductor pipe is tyically set, on petroleum wells, before any drilling operations are performed. It is usually set with special pile-driving or spudder rigs, though the drilling rig is sometimes used to save time and money.

In the offshore drilling industry, the conductor pipe is set in the seabed, and is a key structural foundation for the subsea wellhead. When drilling an offshore well, a marine riser is connected to the well, and this is subjected to large environmental forces such as current and waves which are transferred to the conductor. The forces can be large and also cyclical which can potentially cause fatigue damage to the conductor, especially in harsh environmental conditions. A Conductor tensioner unit (CTU) can be used in shallow water on jackup rig to withstand such damaging forces.

Famous quotes containing the words conductor and/or pipe:

    I was the conductor of the Underground Railroad for eight years, and I can say what most conductors can’t say—I never ran my train off the track and I never lost a passenger.
    Harriet Tubman (1821–1913)

    If you would get money as a writer or lecturer, you must be popular, which is to go down perpendicularly.... You are paid for being something less than a man. The state does not commonly reward a genius any more wisely. Even the poet laureate would rather not have to celebrate the accidents of royalty. He must be bribed with a pipe of wine; and perhaps another poet is called away from his muse to gauge that very pipe.
    Henry David Thoreau (1817–1862)
