Vertebrae Bend Restrictors [VBRs]

A Vertebrae Bend Restrictor (VBR) is a component used in offshore and subsea industries to protect flexible pipelines, umbilicals, and cables from excessive bending. These restrictors prevent structural damage caused by bending forces, which can occur near termination points or in dynamic areas, such as risers exposed to waves and currents.

Key Features and Purpose:

Bend Protection: The VBR limits the minimum bending radius of pipelines or cables, ensuring they are not stressed beyond safe limits.
Modular Design: Our VBRs are made from interlocking elements that fit around the pipe or cable. This allows easy installation at critical points and designed with our Rapid Opening/Closing [ROC (patend pending)] technology for significantly reducing installation timelines.
Material Composition: Our VBRs are constructed from high-strength polyurethane to resist harsh subsea conditions.
Applications: Commonly used in offshore oil and gas operations, floating production systems, and subsea umbilicals to avoid fatigue failure caused by cyclic movements and currents.

Typical Installation Areas:

Riser bases (where risers connect to floating platforms or vessels).
Touchdown points on the seabed.
Cable entry points on platforms or other subsea equipment.

VBRs play a crucial role in ensuring the structural integrity of flexible subsea pipelines and cables, which are subjected to various environmental and operational forces. Our ROC VBR is perfectly suited for all operational conditions.
