The polyurethane bending limiter provides essential submarine cable bending protection at the lower ports of offshore wind power I-pipe and J-pipe installations. This protective component is mounted on the buoyancy module outside marine riser columns.
- Semi-annular female end
- Semi-annular male end
- Snap ring and snap groove connection system
- Auxiliary pipeline channel
- Riser column channel
The innovative snap ring and groove connection system ensures secure assembly, with the snap groove integrated into the semi-annular female end and corresponding snap rings installed on the male end.
As China's offshore energy sector expands, reliable submarine cable protection becomes increasingly critical. Our solutions address the complex challenges faced by submarine cables in demanding marine environments. Flexible risers offer superior compliance and wider application range compared to rigid alternatives.
- Modular bite structure with adjustable length for various service environments
- Harvard structure module design
- High-quality polyurethane material with excellent deformation, corrosion, and wear resistance
- Minimum tensile strength: 45MPa
- Maximum material density: 1.2 × 10³kg/m³ (avoids additional underwater weight)
- 8t lateral pressure capacity
- Bending radius compliant with submarine cable requirements
- Excellent elasticity and corrosion resistance
- Superior hydrolysis resistance and insulating properties
- Protects cables from anchor shocks with urethane elasticity
- Cable-friendly design prevents damage to cable covers
- Exceptional durability in all marine conditions
- 50+ year lifespan in submarine environments
- Excellent dielectric properties
- 1.0m-2.0m basic units reduce weight and installation time
- Eliminates need for barge cranes or secondary vessels during laying
