Abstract: A mooring and flowline system is disclosed for mooring a floating production and/or storage vessel (10) to the seabed (12) and one or more flowlines (22, 24) for connection to one or more producing wells or to a facility. The system comprises at least two anchors in the sea bed (12) and a respective anchor riser (14) extending from each of the anchors to a common mooring node member (18). A mooring pendant (20) extends from the common mooring node member (18), where the mooring pendant (20) has an upper end for connection, in use, to the vessel (10). Each flowline (22, 24) comprises a lower flowline (22) and a flowline riser (24) extending from the lower flowline (22) to the vessel (10). Each flowline riser (24) has part of its length secured to the mooring pendant (20) by one or more guide frames (32) to control sideways and rotational movement.
