Trelleborg has launched an integrated cable protection system specifically designed to protect offshore windfarm power cables.
The Swedish firm’s ‘NjordGuard’ system manages the movement of subsea power cables of monopile and J-tube wind turbines and offshore substations (OSS) in the free span between the seabed and an installation’s aperture.
Trelleborg product manager Andy Smith said the system is specifically designed to protect windfarm power cables from fatigue, over-bending and abrasion due to loads and motions generated by the field wave tidal conditions.
The system incorporates Njord BS (Bend Stiffener) technology, which reduces the risk of failure by managing the dynamic motion and eliminating shock loading on the cable in comparison to a typical ‘vertebra’ style bend restrictor design.
Smith said: “NjordGuard protects the cable both during installation and throughout its life. The innovative product can be easily reconfigured and is suitable for any diameter of cable.
“It can also be retrofitted to existing solutions where failure looks likely to occur, preventing critical loss of power, costly repairs and downtime.”
NjordGuard is produced using Trelleborg’s API 17L certified material for both internal and external components and requires only minimal assembly, the company said.
