Polyurethane Submarine Cable Bend Restrictor PU Underwater Cable Bend Limiter

The bending limiter provides submarine cable bending protection at the lower ports of offshore wind power I pipe and J pipe installations. It is mounted on the buoyancy module outside the marine riser column.

• Semi-annular female end
• Semi-annular male end
• Snap ring and snap groove connection system
• Auxiliary pipeline channel
• Riser column channel

The semi-annular female end connects with the male end via snap ring and groove mechanism. The snap groove is integrated into the female end's outer sides, while the snap ring is installed on the male end for secure connection.
