The invention relates to a suspension device for an oil conveying pipe or hose for loading or unloading of a vessel. The device is cardanic, and during unloading the oil is conducted towards the cardan centre from one or both sides along a horizontal axis through one or more pipe swivels and possibly also bearings. Thereafter, the oil flow is diverted and is conducted back towards the cardan centre along the second cardan axis. After having passed the next pipe swivel the oil flow is diverted to the third cardan axis, and in order to relieve this pipe swivel bearings may be arranged coaxially with the pipe swivel. The pipe bend is in this case suspended in brackets attached to a cylindrical load cell, which in turn pivots in a beam structure which is an integral part of the pipe structure and which pivots about the first cardan axis. The load cell is able to register the hose tension.

L'invention porte sur un dispositif de suspension destiné à un tuyau ou à un flexible de transport de pétrole servant au chargement et au déchargement d'un navire. Le dispositif est de type cardan. Pendant le déchargement, le pétrole est acheminé vers le centre du cardan depuis un seul ou deux côtés le long de l'axe horizontal par l'intermédiaire d'un ou de plusieurs joints articulés et peut-être aussi de paliers. Le pétrole est ensuite détourné et réacheminé vers le centre du cardan en suivant le second axe de ce dernier. Après avoir passé le joint articulé suivant, le pétrole est réorienté selon le troisième axe du cardan. Pour libérer les contraintes s'exerçant sur ce joint, des paliers peuvent être montés coaxialement avec ce dernier. Dans ce cas, le coude du tuyau est suspendu dans des supports attachés à une cellule de charge cylindrique qui, elle-même, pivote dans une poutre faisant partie intégrante du dispositif de suspension et pivotant dans le premier axe du cardan. La cellule de charge peut enregistrer la traction sur le flexible.
