ABSTRACT:
A bend stiffener includes a first elongate member having a longitudinal conduit and a second elongate member also having a longitudinal conduit connected to an end of the first member thereby effectively extending the length of the bend stiffener. The first member has a resilience to bend when the bend stiffener is subject to a certain load, i.e. at a large tension and small angle, while the second member is designed to have less resilience than the first member, whereby the second member starts bending earlier than the first member when the bend stiffener is subjected to a smaller load, i.e. at a low tension and/or a large angle. The first and second members may provide one or more channels from the second member to the hydrophone. The channel surfaces may have a nonmetallic material. The second member has a resilience to transfer incident pressure waves into the channel therein.
