Floating Production Storage and Offloading (FPSO) units are specialized ships used in the offshore oil and gas industry. They are designed to extract, process, and store hydrocarbons from underwater wells. FPSOs can operate in deep waters where traditional platforms are not feasible, making them essential for accessing remote oil fields. Once the oil is processed, FPSOs can store it until it is offloaded to tankers for transportation to shore. This system allows for efficient production and minimizes the need for extensive underwater pipelines, making it a flexible solution for offshore energy extraction.
