With the new custom-made Cable Laying Monitoring System, NKT has further enhance NKT
Victoria’s capabilities to safely install power cables with minimal risk of compromising the
cable integrity during laying operation in even the most challenging site conditions such as
high seas, strong current and low visibility. The new system provides real-time monitoring
and data collection during cable lay ensuring optimal layback tension, departure angle and
touchdown position without any physical contact with the cable.
- We are always aiming to offer the most reliable and efficient power cable installation to our
customers. With the new system we are setting new industry standards in terms of
minimizing the risk of over bending or stretching of the cable during installation. The system
increases the level of digitalisation and integration of the survey system improving the cable
laying performance and reliability, says Claes Westerlind, Executive Vice President and
Head of HV Solutions Karlskrona.
The Cable Laying Monitoring System has been specially designed by NKT in close
collaboration with the software company 4D Nav and is integrated into the hull of the NKT
Victoria. With the hardware hull integration and software integration into the vessels standard
survey system the cable touch down monitoring is not sensitive to high currents like
traditional monitoring based on Remote Operated Vehicle (ROV) positioning.
Debut in challenging waters
The accuracy and reliability of the Cable Laying Monitoring System has already been proven
during operations in challenging site conditions in the UK.
- We have put the new system to the test during the cable laying between the Channel
Islands Jersey and Guernsey in October. These waters are known to pose a rather
challenging environment with strong currents, bad visibility and large tidal differences. The
monitoring system proved an excellent performance supporting NKT Victoria and the team to
install the cable successfully within the planned schedule and with no unforeseen events,
says Claes Westerlind.
NKT Victoria is ranked as one of the world’s most advanced cable-laying vessel and its
design is based on extensive experience with offshore installations. She installs high-voltage
offshore cable systems with exceptionally high precision based on DP3 (Dynamic
Positioning) capability and sophisticated monitoring features. These, and many more cuttingedge
features, contribute to higher efficiency and precision of the installation and service
execution, while offering maximum safety for the crew. NKT Victoria was commissioned in
2017 and has completed operations across Europe.
