Abstract
The present invention relates to a curvature limiter device constituted by fastening tubular sleeves (5) end-to-end, the tubular sleeves being fitted at their longitudinal ends with fastener-and-hinge devices (6) on their top faces and with bottom abutments (71, 72) diametrically opposite on their bottom faces. The present invention also provides a bottom-to-surface connection installation between undersea equipment such as an undersea well head or the end of an undersea pipe resting on the sea bottom (16) and a floating support (12) on the surface, the installation comprising an undersea flexible line (2) having its curvature controlled by a said curvature limiter device (1) of the invention, said curvature limiter device being arranged at an intermediate depth between the sea bottom (16) and the surface (17).
