Bend restrictor

Prevent overbending in subsea flexible systems

Bend restrictors control bending of flexible pipelines, umbilicals and cables at rigid connection points, preventing damage during installation and operation by maintaining a defined minimum bending radius in subsea applications.

Benefits

Controlled bend protection for subsea connections

The bend restrictor uses interlocking elements to form a semi-rigid curved structure, preventing overbending beyond a defined minimum bending radius. Designed for installation at termination points, it improves safety, protects flexible systems and maintains load paths between flexible and rigid structures.

MBR protection
Maintains manufacturers recommended MBR (minimum bend radius) during the life of the project, ensuring flexible pipelines, umbilicals and cables are protected from overbending and buckling in subsea environments.
Load reduction
Reduces loads on termination structures compared to heavy steel alternatives, providing a more efficient load path from flexible systems to fixed subsea infrastructure.
Safe installation
Lightweight, quick, easy and safe to install with multiple handling options, improving offshore installation efficiency while maintaining joint integrity and reducing operational risk.
