An arrangement for buoy loading of hydrocarbons at sea includes a buoy element (5) which is connected to mooring lines (13) and riser lines (11) and is arranged to be received in a recess (8) in the bottom of the vessel (1) in such a way that the vessel can rotate with respect to the mooring lines (13) and the riser lines (11). An upper turning body (18) is turnably arranged in the vessel (1) spaced above the buoy element (5), and flexible conduits (17,23) extend from the buoy element (5) to resiliently supported connectors in the turning body (18). A swivel (29) is arranged on the turning body (18), one side of which is connected to the connectors and the other side of which is connected to a pipe system of the turning vessel. The turning body (18) is provided with devices (27,28) for turning it in steps with respect to the vessel in order to keep the turning body (18) and the buoy element (5) within a predetermined mutual angular relationship when the vessel turns about the buoy element (5) due to environmental forces. |
