Our shock-resistant Polyurethane (PU) protective tubes act as a high-durability "armor," providing a 25-year maintenance-free service life for critical power cables, fiber optics, and umbilical lines.
Technical Features & Material Excellence
1. Symmetrical Interlocking Architecture: The split-shell design allows for rapid "snap-on" installation on the vessel deck, significantly reducing offshore operational hours and vessel day-rates.
2. Advanced Material Science: Manufactured from premium, high-density Polyurethane (PU) characterized by:
3. Impact Resilience: High energy absorption capacity that "bounces back" after impact, unlike rigid steel or concrete.
4. Hydrolysis Resistance: Specifically engineered to prevent degradation, swelling, or loss of mechanical properties in long-term saltwater immersion.
5. Extreme Abrasion Resistance: Outperforms traditional rubber and metallic sleeves in sandy or rocky environments.
6. Modular Maintainability: The segmented structure allows for localized inspection and cost-effective replacement of specific sections without decommissioning the entire line.
Strategic Application Sectors
1. Offshore Wind (Fixed & Floating)
Touchdown Protection: Safeguards array and export cables at the critical transition point from the J-Tube or I-Tube to the seabed.
Scour Protection: Prevents cable abrasion caused by seabed mobility and sediment movement around turbine foundations.
Cable Crossings: Provides reliable separation and crush resistance where new cables intersect existing infrastructure.
2. Offshore Oil & Gas
Umbilical & Flowline Shielding: Protects sensitive hydraulic and electrical lines from Dropped Objects (e.g., equipment or anchors) in high-activity zones.
Piggyback Bundling: Securely bundles smaller secondary lines to main pipelines, ensuring synchronized protection and stability.
Why Choose Our PU Solution?
Traditional protection methods like concrete mattresses or cast iron shells are heavy, prone to corrosion, and logistically complex. Our Polyurethane solution offers a lightweight, corrosion-proof, and impact-absorbing alternative that lowers the Total Cost of Ownership (TCO) and enhances the reliability of your subsea network.
In order to facilitate handling of the casing offshore, the usual span length of the polyurethane protective tube is around 100 meters; however, special lengths can be made in order to satisfy project-specific needs.
