We designed, manufactured and installed the entire impressive 145 kV three-core XLPE HVAC submarine cable system. It is 163 kilometres long and plays a key role in making the oil and gas feld more carbon-effcient. It has low electrical losses, excellent tensile strength to withstand the harsh conditions of the North Sea and includes three fber optic links.
We also supplied a 3.5-kilometre 17.5 kV infeld cable including 500 metres of dynamic cable that connects the platform to a FSO (foating storage and offoading vessel). The dynamic cable is designed to withstand the motion of the FSO caused by wind, waves and current.
The main cable system was produced at NKT’s state-of-the art production facilities in Karlskrona, Sweden. It goes out from Kollsnes, is connected to the Martin Linge platform and was delivered in two sub-lengths, connected with a rigid feld joint and installed at water depths reaching 358 meters. The infeld cable parts were jointed and tested at the factory before being laid on the seabed between the platform and the FSO.
NKT’s capacity, competence and pioneering work will surely continue to break new ground. We delivered a world unique dynamic cable – as well as a world record length AC cable system.
