Abstract: The invention relates to a device for transferring fluid between the sea bottom and the surface, especially for recovering and bringing up oil produced by an underwater formation, comprising at least one flexible tubular pipeline extending in a chain between a surface support and an intermediate member imparting to the pipeline, over some of its length, a curved configuration with a concavity facing the bottom, a part of the pipeline between said intermediate member and the sea bottom being tensioned and being fastened to the bottom at a fixed point. … It comprises means for retaining at least one zone of said lower part of the pipeline (3), which means are connected to the fixed point, consisting preferably of an anchorage (5), and which are designed to keep under tension the part (3b) of the pipeline located between the intermediate member (4) and the retaining means and to impart to the pipeline, in a vertical plane, a predetermined set curvature, the concavity of which is directed towards the structure, especially a wellhead (2), which is located on the sea bottom and from which the oil is to be brought up. … …
