The FLNG vessel is operated in dynamic positioning mode for station control of the FLNG vessel 5 within a station keeping envelope at a production location. The system includes a computer processor for receiving a set of real-time monitored location data indicative of the longitude and latitude of the FLNG vessel, wherein the computer processer is programmed with a mathematical algorithm to: (i) compare the set of real-time monitored location data to a set of stored station keeping set points held in a data storage means; (ii) 10 generate a station control correction signal when the set of real-time monitored location data indicates that the FLNG vessel is not positioned at a desired stored station keeping set point; and, (iii) transmit the station control correction signal to the dynamic positioning control system.
