Steel Vertebrae Bend Restrictors

The steel vertebrae bend restrictor (SVBR) is designed to prevent damage to the umbilical control line that it supports at higher loads than its polyurethane counterpart. SVBR assemblies, like their polyurethane counterparts, protect the control line to a customer specified minimum bending radius (MBR).

The SVBR Assemblies are comprised of male and female type segments that fit into each other.  The male segment pair is locked inside the adjacent female segment pairs, thereby reducing the number of fasteners required to complete the assembly. SVBR assemblies are equipped with polyurethane stress wafers that work to evenly distribute the stress during loading.
