To meet the very tight timeframe, we executed many preparations and operations simultaneously. We used our experience and expertise to design a solution that covered the specific requirements for efficiency and sustainability.
The cable system was manufactured in Karlskrona, Sweden, at the NKT plant fed purely on green energy. The cable is protected by double layers of armor wires and capable of transmitting power at 90 kV (kilovolt) of AC (alternating current).
The cable was loaded onto and installed by NKT Victoria. She is one of the world’s most advanced cable installation vessels, loading cable using only onshore power and running more efficiently than other cable-laying vessels at sea, reducing CO2 emissions with 55 %. She enables high precision offshore installation of HV cable systems.
Despite the typical tough sea conditions with strong tidal currents and bad visibility in the channel area, NKT safely installed the 37.4 km long cable system. The next generation cablelaying monitoring system on NKT Victoria provided real-time monitoring and data collection, ensuring optimal installation conditions. It played an important role when we replaced the GJ1 link – on budget and on record time 8 months from contract award to energization of the power link.
