An offshore oil rig is a large structure used to extract oil and natural gas from beneath the ocean floor. These rigs are typically located in deep water and are equipped with drilling equipment, living quarters for workers, and facilities for processing the extracted resources. They play a crucial role in the energy industry by tapping into underwater oil reserves. Offshore oil rigs can be classified into various types, including fixed platforms, floating production systems, and submersible rigs. Each type is designed to withstand harsh ocean conditions and ensure the safety of workers while maximizing oil production efficiency.
