We just learned about the Drilling Rig.
Another way to drill for oil is an Oil Platform or Offshore Platform.
This is a big building out in the water that has drills going down into the water to the ocean floor.
The drill digs down below the ocean floor to drill for oil and then bring it back up to the oil platform.
Some oil platforms have big metal posts holding them still in the water, and some are just floating on top of the water.
