I found something ...

Does  anybody  know  if  the  oil  they  pump  out  ,   some  of  it  is  used  to  run  the  pumps ?

A  sort  of  self  fed  system  ?

Crude oil can’t be used to drive engines, it has to be refined first.

You can, heavy fuel oil is basically the slime left over after distillers do there stuff, its sold dirt cheap to ocean ships.

But they also have a big flamy thing burning fuel on most rigs, i should think thats a likely source of energy.

Oil rigs on the whole are connected to the sea bed via either a sunken tower, or in deeper environments with cables staying a floating rig.

Yes, as I said it goes through the refining process, they don’t use the crude directly. Even that left over slime has to be processed before it’s used, as explained in the article.

When oil is extracted from wells, it’s often accompanied by natural gas. There’s no economical way to store and use that natural gas, so it’s burned (“flared”) right at the site.

This is done on board by the engine as stated in the article

The heavy fuel oil is taken on board and stored in the bunkers. The bunkers contain steam coils and maintain the HFO at 104ᴼF.

From the bunkers the HFO passes through a strainer and tube/shell heater into a positive displacement pump that discharges the oil through a pair of duplex magnetic filters where any ferrous metals are removed.

"Oil rigs on the whole are connected to the sea bed via either a sunken tower, or in deeper environments with cables staying a floating rig. "

my father-in-law, who worked his entire career in the oil industry in New Orleans, once told me that modern oil rigs maintained their position without any physical connection at all...he said the modern rigs utilized a GPS system with engines holding position.

not so?

I should ask your father inlaw Jimbo.

too late...gone to that great gusher in the sky.
BTW: i didn't say i knew it to be true...seemed a bit difficult to me to believe any GPS system/propeller driven platform to maintain such a precise position.

only reason i mentioned it was due to his life long experience in the industry; and altho i didn't know him well, didn't find him to be a bullshitter.

There are several types of oil rigs jimbobghost, I think the type described below is what you were talking about, they are called "floating production systems"

"As oil companies expand into ever-deeper waters, they've had to embrace less traditional methods of getting oil up to the surface. This often means deepwater rigs are buoyant and semisubmersible, floating partly above the surface while pumping up oil from deep wells. Some use wire and rope to connect with a stabilizing anchor, while others — including the now-sunken Deepwater Horizon, pictured at right in June 2009 — are "dynamically positioned," using computer-coordinated thrusters to keep them in place.

thanks for the link, interesting how much there is to learn.

also glad to know my father-in-law wasn't bs-ing me.

hahaha, why would he bs you? You are a scientist, he knew better.

[jimbobghost]

i'm sure you are putting me on, but I have little higher education; this is why I enjoy learning so much in this forum.

I am sincere.
