Balmoral FibreFlex™
Cable protection system featuring integrated stability system

Our technical and engineering teams developed a unique fibre-reinforced cable protection solution designed to provide maximum performance for life of field installations: Balmoral FibreFlex.

The patented system mechanically locks to the end connectors removing a reliance on PU bonding while providing market-leading strain and stiffness levels that are unachievable using traditional PU manufacturing methods.

Integrated stability system

Our stability solution, which complements FibreFlex, offers enhanced tensile and creep performance and is proven to offer up to 75% movement reduction in subsea environments with a corresponding trebling of cable life subject to seabed topology and metocean data.

Both innovations contribute to greatly increased fatigue life.

Key benefits

  • Patented fibre-reinforced technology
  • Ultimate life of field performance
  • Mechanical locking design
  • Industry-leading fatigue life, strain and stiffness performance
  • Improved axial tension and elongation
  • Increased long-term creep performance
  • Optimised bending control
  • Slimline profile
