Trelleborg introduces cable protection system

0

Trelleborg has introduced the NjordGuard integrated cable protection system developed and designed to protect offshore wind farm power cables.

The NjordGuard system manages the movement of subsea cables of monopile and J-tube wind turbines and offshore substations (OSS) in the free span between the seabed and an installation’s aperture.

“Our NjordGuard cable protection system is specifically designed to protect wind farm power cables from fatigue, over-bending and abrasion due to loads and motions generated by the field wave tidal conditions. It incorporates Trelleborg’s market leading Njord BS (Bend Stiffener) technology, proven to reduce the risk of failure by better managing the dynamic motion and eliminating shock loading on the cable in comparison to a typical ‘vertebra’ style bend restrictor design.

Andy Smith, product group manager for Trelleborg’s applied technologies operation.

The system will protect the cables both during the installation and throughout its life, and it can easily be reconfigured to suit any other 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.

Trelleborg’s API 17L certified material is used for the production of both internal and external components of the NjordGuard.
