R&D of dynamic low voltage cables between the buoy and floating hub in a marine energy system
Research Project, 2015 – 2018

Technology to convert energy from the sea, mainly from waves or tides can normally generate electrical power in the order of 100 kW for each unit where a large number of devices are connected to form a sea-based energy system that can eventually be connected to the onshore grid. In this project a mathematical model for power cables with fixings will be developed to simulate the cable movements and to calculate the fatigue failure of the electrical conductor. The model will be calibrated using different variants of prototype cables which will be produced by NKT Cables and tested in field trials for typically six months at the test facility at Runde Environmental Center outside Ålesund in Norway as well as at EMEC in Scotland. In Ålesund cables designed and manufactured for Waves4Power will be used and in Scotland cables for CorPower. Based on the model and field tests a method for laboratory accelerated fatigue tests will be designed, set up and evaluated.
