Custom Vertebrae Bend Restrictor for Offshore Energy

Philson engineers this vertebrae bend restrictor as a modular protection system to safeguard marine energy pipelines and power cables at rigid interfaces. The system utilizes a symmetric, interlocking "vertebral" structure, which allows Philson to effectively manage cable bending. This design prevents stress concentration and ensures that cables remain within their safe operational bending radius.

Engineering Advantages of Vertebrae Bend Restrictor

High-Performance Materia: The system offers exceptional resistance to wear, chemical degradation, and fatigue. Philson ensures the material remains stable across a wide service temperature range of -62°C to 93°C.

Rapid Installation: This configuration allows installation teams to perform quick and site-friendly assembly, which significantly reduces subsea installation time.

Adaptive Mechanical Interlock: The modules lock securely at the specified minimum bending radius, which prevents damage caused by over-bending at critical transition zones.

Precision Engineering: The system is available in hardness grades of 70D or 85D, which Philson customizes to provide the optimal balance of rigidity and impact resistance for specific project requirements.

Versatile Compatibility: Philson designs the VBR to support cables ranging from 13 mm (0.5 inch) to 406 mm (16 inches)** in diameter, and Philson allows for full scalability in system length.

Core Applications of Bend Restrictor

Philson engineers these VBRs for static and quasi-static subsea applications, including:

Subsea Energy Assets: The VBRs protect oil flowlines, power cables, and umbilical lines.

Interface Security: Clients deploy the VBRs at critical connection points such as riser bases, PLEM (Pipeline End Manifolds), and wellheads.

Marine Infrastructure: The VBRs provide essential protection for offshore wind farm arrays, oil & gas platforms, and submarine communication cable landing points.
