What does an offshore oil rig actually do with the oil?

Question

I don't see a storage tank on them, nor a long distance pipe to shore. Where does the oil go???

Answer 1

Into underwater pipelines once it is a producing well.

Answer 2

The oil rig pumps the oil from the source (the earth) down pipe lines to the oil refinery to process into other products.

Answer 3

sometimes the underwater legs of the rig hold the oil.  The legas can be 10 feet or more in diameter and a 1000 feet tall. The oil can be pumped onto barges and taken to an onshore facility.
