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 love music, hear it; go to operas, concerts and pay fiddlers to play to you; but I insist on your neither piping nor fiddling yourself. It puts a gentleman in a very frivolous, contemptible light.... Few things would mortify me more than to see you bearing a part in a concert, with a fiddle under your chin, or a pipe in your mouth.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
