NjordGuard CPS

NjordGuard

NjordGuard is an innovative cable protection system designed and developed to protect offshore wind farm power cables in both monopile and J-tube applications.

Offshore efficiency
NjordGuard has been engineered for ease of vessel-based assembly, a key factor in reducing offshore time, vessel costs, and operational risk. This efficiency is achieved without compromising on cable protection, ensuring safe, consistent performance even in harsh offshore environments.

Latch connector design
The system’s external stiffener and connector are delivered preassembled with a pull-in tool and rigging, reducing deck work and speeding up the cable pull-in process. Its ROV removable compact design ensures smooth entry into the monopile aperture with minimal resistance. The optimised part count and robust design ensure a reliable and trouble-free operational life, which can accommodate a larger range of aperture tolerances.

Super duplex interconnectors
A major advancement is the anode free super duplex interconnectors, which allows for rapid assembly without the need for rotational or symmetrical alignment. This simplifies offshore handling and significantly reduces installation time, while offering strong structural performance and corrosion resistance. The design also has significant thermal benefits over the previous version, as well as offering a 44 % increase in packing efficiency. The main wall of the PU profiles now offers a 40 % improved wear resistance / life and a 5 kJ impact rating.

Sleek ballast
The sleek ballast is available in preassembled lengths of up to five metres. Its simplified two-part design reduces the number of components that need to be handled during offshore operations. Its smooth outer profile ensures clean travel over cable lay vessel rollers and through the overboarding chute, supporting efficient and consistent installation. Its smooth inner profile minimises potential wear points on the cable, reducing the risk of cable failure due to internal abrasion. The anodes now sit inside recessed pockets, to protect them during handling, installation and life subsea.
