They are fabricated on land. Typically they mobilized (moved) to location by barges. A jackup rig may be assembled in pieces, with the jacket or the rig structure being installed first, and then the topsides (all housing and equipment that rests on the structure) is installed second, by large cranes. See related link.

A semi-submersible, like the Deepwater Horizon, may be towed by tugboats to its location. See second related link.

Why was the oil rig invented?

Oil deposits were found beneath the ocean, too far from the shore to drill from the land. Eventually someone had the bright idea to go and produce these rigs that drill at sea and the first oil rig was born. So, oil rigs were invented to pump the oil located beneath the sea bed far from shore.

Do oil rig platforms float?

Most oil rig platforms today do not float. The platform is usually positioned atop several pillars that extend to the bottom of the sea bed on which they are located. Newer technology however, has developed barges that contain oil drilling equipment. These newer barges do float but must rely on precise electronics to keep them positioned within a couple of feet about the drill site on the sea bed.

How does oil get from gulf of Mexico oil rigs to refinery?

If the rig is relatively close to the sea shore and is located on shallow waters, oil pipes running through the ocean floor are enough to transport the unrefined oil. Otherwise, oil tankers (huge ships with carrying capacity of 2 billion metric tons of oil) are used to transport the oil from the rig to the refinery.
