Prysmian will be responsible for the design, supply, termination, testing, and commissioning of one 66 kV three-core export submarine cable with EPR insulation for a total of 25 km and attached another 66kV submarine dynamic cables with EPR insulation for about 1 km connecting the shore to a floating substation. Prysmian will also provide an additional 3 km of onshore 66 kV cables with XLPE insulation.
