The importance of submarine cable protection
In offshore wind farms, oil and gas fields, and undersea infrastructure, submarine cables are the lifelines of energy transmission and communication. However, these critical assets are constantly exposed to threats such as mechanical impact, seabed abrasion, tidal currents, and stress related to installation. That’s where polyurethane submarine cable protection tubes come into play.
The role of polyurethane cable protection tubes
Polyurethane protection tubes serve as underwater cable protectors, ensuring that power cables, umbilicals, and fiber optics remain intact throughout their service life. Features of these protection sleeves:
• Prevent excessive bending and localized compression
• Absorb impact and vibration
• Reduce friction against steel structures or the seabed
• Extend the life of offshore and subsea cable systems
Their modular or split-sleeve design allows for easy installation during both topside and subsea operations, while the inherent elasticity and wear resistance of polyurethane offer superior protection even in harsh marine conditions.
Structural features of polyurethane subsea cable protectors
Material: High-performance polyurethane with customizable hardness (typically 80–95 shore D)， friction, and corrosion-resistant. Polyurethane material is lighter.
Design: Split-tube, snap-fit, or bolted structures for fast on-site assembly
Customization: Tailored to specific cable diameters (e.g., 130mm–310mm) and environmental loads
