Abstract
(EN)
The invention relates to a device for transporting fluid between two anchored to a sea bottom (5) floating supports (2, 3) comprising an under-sea central rigid pipeline (1) which is placed in a subsurface and whose each end (1a, 1b) is connected to said support, respectively by means of a flexible pipeline (11, 16), in which: a) the running portion of said central rigid pipeline (1) comprises or interacts with buoyancy elements (8) in such a way that the central rigid pipeline (1) is arc-shaped in a quasistatic standstill state thereof, preferably according to a curve, substantially in the form of a chain, in such a way that the absolute values of angles (X1, OC2) between half-straights of the axes (XX', YY') of the rigid pipeline and the half-straights to each end (1a, 1b) in the direction to the other end (1a, 1b) are less than 20°, preferably less than 15°, and b) the lengths and curves of the flexible pipelines (11, 16) are selected such that the modifications of the curvatures thereof are enabled to compensate the movements of the floating supports.
(FR)
La présente invention a pour objet un dispositif de transfert de fluide entre deux supports flottants (2, 3) ancrés au fond de la mer (5) comportant une conduite sous-marine rigide centrale (1) installée en subsurface, dont les extrémités (la, Ib) sont reliées chacune respectivement à un des deux dits supports par l'intermédiaire d'une conduite flexible (11, 16), dans lequel a) la partie courante de ladite conduite rigide centrale (1) comprend ou coopère avec des éléments de flottabilité (8) de sorte que la dite conduite rigide centrale (1) adopte en état quasi-statique de repos une configuration en forme d'arche, de préférence selon une courbe sensiblement en forme de chaînette telle que les angles ((X1, OC2) entre les demi-droites des axes (XX', YY') de la dite conduite rigide et les demi-droites horizontales à chacune de ses extrémités (la, Ib) en direction de l'autre extrémité (Ib, la), sont en valeur absolue inférieurs à 20°, de préférence inférieurs à 15°, et b) les dites conduites flexibles (11, 16) ont des longueurs et courbures, de sorte que les variations de courbure des dites conduites flexibles sont aptes à compenser les mouvements des supports flottants.
