| 摘要 |
<p>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.</p> |
