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. According to the invention the turning device is connected with the piping system, via at least one swivel means (21,22) of a kind known per se, for each fluid, each swivel means having first and second mutually rotatable swivel members (24,25), between which fluids may be transferred during mutual rotation of the swivel members, first and second swivel members (24, 25) of swivel means (21, 22 ) being substantially non-rotatably connected with turning device (5), and hull (2), respectively.
