Oil and gas awaiting transport was stored in tankers called floating storage and offload units (FSO). FSOs were used to store extracted hydrocarbons (a mixture of oil, gas and water) and transport it from remote locations such as distant seabeds. However, FSOs can''t process oil and gas, which is where the FPSO comes in.
