oil platform

An oil platform is a structure that is built in the ocean to collect oil from beneath the surface. It is like a big tower made with metal, and it is fixed to the ocean floor. It has a hole in the sea floor where the oil can be extracted and brought up to the platform to be stored. The platform also has living quarters for any people who live and work on it, as well as machines and equipment to help with the oil collection process.
