Product Overview

The polyurethane bending limiter provides essential protection for submarine cables at lower ports of offshore wind power I-pipe and J-pipe installations. Designed for installation on buoyancy modules outside marine riser columns, this solution ensures long-term reliability in challenging marine environments.

Structural Design

The innovative design features:

Semi-annular female and male ends with snap ring/groove connection system
Integrated auxiliary pipeline channel and riser column channel
Precision-engineered snap groove arrangement on female end
Position-matched snap ring installation on male end

Technical Requirements

Modular bite structure with adjustable length for various service environments
Harvard structure module design
High-quality polyurethane material with exceptional deformation resistance, corrosion resistance, and wear resistance
Minimum tensile strength: 45MPa
Maximum material density: 1.2 × 10³kg/m³ (adds no underwater weight to cables)
8t lateral pressure capacity
Bending radius compliant with submarine cable requirements

Material Characteristics

Excellent elasticity and corrosion resistance
Superior resistance to hydrolysis
Effective insulation properties
Protects cables from anchor shocks through urethane elasticity
Cable-friendly design prevents damage to cable covers
No abrasion under any marine conditions
50+ year durability in submarine environments
Excellent dielectric properties

Installation Advantages

Workability: Basic units in 1.0m-2.0m lengths provide lighter weight and reduced installation time. No need for barge cranes or secondary work vessels during cable laying operations.
