Benefits

Accurate solution for subsea crossing protection

Polyspace uses interlocking HDPE (High Density Polyethylene) half-shells fastened around the cable to create a controlled standoff distance. Installed during deployment, it ensures separation from existing pipelines, reduces installation complexity and provides a cost-effective alternative to rock dumping or subsea bridges.

Clearance control
Generates a guaranteed 350 mm clearance between cables and pipelines at crossing points, ensuring safe separation and preventing interaction or noise transmission between subsea infrastructure during installation and operation.
Easy installation
Installed onto the cable during deployment from the vessel, removing the need for pre-lay operations and reducing costly offshore vessel time compared to rock dumping or subsea bridge solutions.
Integrated system
Becomes an integral part of the cable system using interlocking HDPE shells and cable clamps, providing a cost-effective and accurate solution for subsea crossing protection requirements.
