It has functions such as oil and gas separation, oily wastewater treatment, power generation, heating, crude oil product storage and transportation. The appearance of FPSO is similar to that of an oil tanker, but its complexity is much higher than that of an oil tanker. FPSO is currently the most widely used floating production and processing facility in marine oil and gas development. It is usually composed of several major parts such as the upper module, hull, mooring system, and underwater production system.
