What is the difference between an “oil rig” and “oil platform”?
One is a land based rig the other marine based but both are oil rigs. Offshore drilling rigs, fixed platforms, exploration and floating platforms are all oil rigs.A drilling rig may move from one location to another or float on the surface of the water. A production platform does not move. There are many types of platforms and there are also drilling ships with drilling derricks on the ships. Drillships are designed to carry out drilling operations in ultra-deep waters where even most Semi-Submersibles can not drill. Land based oilrigs are called oilrigs or drilling sites. Both offshore and land rigs are oil installations.
