<p>A device for connection or suspension between a detachable flexible or semi-flexible riser pipe (4) and a pipe system (14) on a fixed or floating platform or ship (15). The suspension system (1, 2, 3) consists of a rotary connection which is designed in such a way that the connection between the riser pipe (4) and the pipe system (14) is moment-free or mainly moment-free. The rotary connection may appropriately consist of a swivel housing (3) which, on one side, is fitted with a first tubular shaft (1) which is connected to the pipe system (14) on the platform or ship and, on the other side, is fitted with a second tubular shaft (2) which is arranged in a swivel housing at an angle of 90 to the first tubular shaft (1) and which is connected to the riser pipe (4). The two shafts (1, 2) communicate with each other via a cavity in the swivel housing (3) but are closed to the surroundings at their ends.</p> |
