Vertebrae Bend Restrictors (VBR)

Tekmar’s Vertebrae Bend Restrictors (VBR) are engineered to limit excessive bending and protect subsea cables, umbilicals and flexible pipelines throughout installation and operational life. Designed for dynamic offshore environments, VBR systems help safeguard critical subsea infrastructure from damage caused by mechanical loading, seabed interaction and unsupported free spans, supporting long-term integrity and operational reliability.

Proven bend restriction solutions trusted across offshore wind and oil & gas projects worldwide.

Manufactured using robust polymer materials and a lightweight modular design, Tekmar’s Vertebrae Bend Restrictors provide a flexible, interlocking solution engineered for efficient installation and dependable offshore performance. Designed to integrate with Cable Protection Systems (CPS) and tailored to specific project requirements, VBR systems support offshore wind, oil and gas, interconnector and marine infrastructure applications worldwide.

Key Features

  • Designed to limit excessive bending of subsea cables, umbilicals and flexible pipelines
  • Helps protect against mechanical loading, seabed interaction and unsupported free spans
  • Lightweight, modular and interlocking design for simplified handling and offshore installation
  • Configurable to meet project-specific load, cable diameter and environmental requirements
  • Robust polymer construction engineered for harsh offshore conditions
  • Designed to integrate with Cable Protection Systems (CPS) for enhanced subsea protection
  • Resistant to impact, abrasion and hydrostatic pressure in demanding subsea environments
  • Engineering, testing and project support available from design through installation

Applications

Vertebrae Bend Restrictors support a wide range of offshore infrastructure applications, including:

  • Offshore wind export and inter-array cable systems
  • Oil and gas umbilicals and flexible pipeline protection
  • Dynamic and static subsea cable systems
  • Subsea power, fibre optic and communications infrastructure
  • Interconnector and marine infrastructure projects

Proven Track Record

Tekmar’s Vertebrae Bend Restrictors have been successfully deployed across offshore wind and oil & gas projects worldwide, supporting developers, operators, EPCs and contractors with trusted bend restriction solutions for demanding offshore environments.

Backed by decades of offshore engineering expertise and integrated subsea protection capability, Tekmar helps customers safeguard long-term cable, umbilical and flexible pipeline performance.
