Reinforce your cables with a lighter, stiffer alternative to steel

Deeper installations increase the mechanical demands on cable structure, axial load, and handling. At depths beyond 1,000 meters, conventional steel armoring adds significant weight, limiting cable design and installation options.

Operational consideration	Steel armoring
Specific gravity	~7.85 (8,000 kg/m³)
Impact on cable weight	High self-weight increases axial load and limits depth viability
Processing requirements	Requires rewinding and bitumen coating; short lengths per bobbin
Corrosion behavior	Requires protection against seawater exposure
Design flexibility	Larger diameter and weight limit routing options
Environmental considerations	Petroleum-based coatings and heavier transport requirements

Twaron® UHM armoring

~1.45 (1,450 kg/m³)

Lighter material reduces load, enabling deeper installation and longer unsupported spans

No coating required; longer runs possible; compatible with standard equipment

Inherently resistant to corrosion and marine degradation

Supports compact designs, tight bends, and suspended routing

Cleaner manufacturing and reduced vessel trips lower environmental impact
