发明名称 Bend stiffener
摘要 A bend stiffener 2 is disclosed for preventing excessive bending of an elongate member, e.g. a marine riser, in a region where it enters a tube, e.g. an "l" or "J" tube mounted on a hydrocarbon extraction platform. The bend stiffener has an elongate sleeve 8 having a through-going cavity which receives the elongate member in use. The sleeve is to be mounted by means of (i) a mating part 18 received by the tube and (ii) an axial locating arrangement 6, 12, 14, 16. The axial locating arrangement is designed to permit at least some angular movement. As a result bending moments are borne by the engagement of the mating part 18 with the tube. The axial locating arrangement does not suffer large bending moments and so problems of fatigue in this area are alleviated.
