NKT created a turnkey cable system solution and completed the project on time.
We used our market-leading expertise at our excellent factory in Karlskrona, Sweden, to design, manufacture and test the 36 km of single-conductor 400 kV (kilovolt) high-voltage alternating current (HVAC) XLPE cable systems. Meanwhile, we prepared the sensitive onshore installation sites. We took, for example, measurements to protect the nature reserves, including an old burial ground dating back to the Stone Age and Bronze Age. Boskalis recycled the outdated cables, loaded the new ones onto an installation vessel and performed the offshore installation. Each cable was carefully pulled in through a pipe at landfalls
to ensure mechanical protection, time savings and risk reduction. From the substation on each side, NKT specialists installed the onshore cables, routed them to shore and jointed them perfectly to the offshore cables. At the substations, we connected them to terminations. Our high level of experience and knowledge came in handy as we had to manage several parallel activities, and our close cooperation with partners and customers ensured a truly successful project. We completed testing, commissioning and energizing within the challenging deadline.
