Abstract: A system for transferring fluids from a piping system in a ship'hull (2) to a turning device (5) which is rotatably connected thereto, during offshore produciton of oil or gas. The turning device is arranged for being anchored to the sea floor and for connection with at least one flexible riser (12, 13) and with hoses (56, 57, 76, 77), which are connected with the piping system via a manifold (14, 15) for each flow of fluid.In order to permit unlimited mutual rotation of the turning device and the hull, sets of first coupling halves (54, 55, etc.) are provided along the periphery of the turning device (5), and are connected with manifolds (14, 15).

Abstract: A system for transferring fluids from a piping system which is firmly connected with a ship's hull (2) to a turning device (5), and vice versa, in which the turning device is rotatably connected with said hull. The turning device has a through hole (7) coaxially with its axis of rotation, through which a drill string, a rigid riser, or the like may be run by the aid of a derrick (16). Furthermore, turning device is arranged for anchoring to the sea floor and connection with at least one flexible riser being connected with respective devices which are firmly connected with the sea floor, and with hoses which are connected with the piping system in the hull.
