A Bend Stiffener is designed to add local stiffness to cables and umbilicals at the point of connection to a rigid structure, thereby limiting bending stresses and excessive curvature. BMP's Bend Stiffener systems can be used in static or dynamic applications and typically incorporate integral steelwork necessary for interfacing with clients' connecting structures.

A Static Bend Stiffener is primarily utilised to protect cables from over bending during installation and over-deck deployment from lay vessels and typically manufactured as a one piece cone shaped Polyurethane moulding, facilitating easy positioning over the cable or umbilical ends.

If the Bend Stiffener is required for use in dynamic applications (dynamic bend stiffener), BMP's Polyurethane polymer system has significantly enhanced fatigue properties and integral design parameters to prevent failure as a result of cyclic loading.

Split Bend Stiffeners - In instances where there are particular deployment difficulties due to physical or environmental issues, BMP offers a Split Bend Stiffener design, facilitating part installation prior to cable/umbilical pull-in.

The two mating halves of the Bend Stiffener are typically held in position by a super duplex bolting system, where the second mating half is assembled in position following completion of the pull-in procedure. BMP offers Split Bend Stiffeners in Dynamic or Static designs.
