Title (EN) Bend Restrictor
(FR) LIMITEUR DE FLEXION
Abstract:
(EN) An apparatus (1) for restricting the bending of a tubular member underwater comprises a plurality of interlocking modules each formed from a first half shell component (2) circumferentially displaced from a second half-shell component (3), wherein the first half shell component comprises one or more projections (19) extending from a side edge (18) thereof and the second half shell component comprises one or more grooves (21) in a side edge (18) thereof, the projections and grooves being angled to the side edges of the first and second half shell components, the arrangement being such that when assembled together each of the one of more projections of the first half shell component are inter-engaged with a corresponding groove of the second half shell component to secure the two half shells together.
(FR) La présente invention concerne un appareil (1) pour limiter la flexion d'un élément tubulaire sous l'eau. Ledit appareil comprend une pluralité de modules de verrouillage, chacun formé à partir d'un premier composant de demi-coque (2) déplacé de manière circonférentielle à partir d'un second composant de demi-coque (3), le premier composant de demi-coque comprenant une ou plusieurs saillies (19) qui s'étendent à partir d'un bord latéral (18) de celui-ci et le second composant de demi-coque comprenant une ou plusieurs rainures (21) dans un bord latéral (18) de celui-ci, les saillies et les rainures étant inclinées par rapport aux bords latéraux des premier et second composants de demi-coque, l'agencement étant tel que, lorsqu'ils sont assemblés, chacune de la ou des saillies du premier composant de demi-coque est en prise mutuelle avec une rainure correspondante du second composant de demi-coque pour fixer les deux demi-coques l'une à l'autre.
