Apparatus is disclosed for transferring fluid between a point (5) on the seabed, such as a wellhead, and a floating vessel (1). The apparatus comprises a flexible pipeline (4), the upper end of which is attachable to the vessel (1). A second flexible pipeline (8) is attached at one end to the wellhead (5). A structure (6) is mounted on the seabed and includes a member (7) which is movable relative to the structure (6). The lower end of the first pipeline (4) and the upper end of the second pipeline (8) are mounted on an end of the movable member (7) which is remote from the seabed structure (6). When the first flexible pipeline is stretched out in response to the vessel (1) moving about under the action of wind and current, the movable member (7) is displaced relative to the seabed structure (6) in order to allow the pipeline (4) a greater range of movement before it becomes stretched beyond its safe limit. The apparatus is particularly useful in shallow water where the length of the flexible pipeline (4) is not sufficient to take up very much movement of the vessel (1).
