NKT DynCables Project

– Dynamic characteristics of electric cables for use in the field of offshore energy

NKT is one of Europe’s largest cable manufacturers with a strong history of innovation. Today they develop a new generation of cables to service the unique requirements of wave and tidal energy by working with Swedish technology developers Waves4Power, CorPower and Minesto. Irrespective of the principle used to convert waves or tides into electrical energy, power cables play a vital role in getting that energy to shore so it can generate revenue. The project centres on the energy technologies of Waves4Power, CorPower and Minesto supported by RISE (Research Institutes of Sweden) and Chalmers University of Technology. The first field trials have been performed at Waves4Power’s demonstration site in Runde, Norway. Following the trials, numerical models will be validated against data collected by the monitoring equipment mounted on the wave energy converters and on the cable itself. Based on the model and field trials, the project will develop a method of accelerated fatigue testing in a laboratory environment which will evaluate different cable designs and feed into a lifetime model based on the VMEA methodology.


The Ocean ERANET RiaSoR I project is currently establishing a framework for reliability assessment within the ocean energy sector, which builds upon established practices from the automotive industry. Within this project leading WEC/TEC developers are providing results from their onshore testing to identify critical components and parameters that influence uncertainties and safety factors. RiaSoR II is aimed at taking the RiaSoR I theoretical reliability assessment framework and applying it to the field test programme for WEC/TEC developers to validate the findings, establish a practical monitoring platform and framework to prepare for future arrays were big data handling and processing will be vital to drive down operational expenditures (OPEX).

The project brings together renewable energy leaders from Sweden, Scotland and Portugal, Research Institutes of Sweden (RISE), European Marine Energy Centre (EMEC), ORE Catapult, Cruz Atcheson,  Alkit Communication AB, Synective Labs AB, Corpower Ocean AB, Waves4Power AB, Ocean Harvesting Technology AB and Albatern.

CorPower Ocean AB, a leading developer of high efficiency wave energy converters, has been awarded a €4m grant by the European Commission (EC) for its WaveBoost project.

The grant will support a three-year innovation programme targeting significant improvements in the reliability and performance of wave energy converters by using pneumatic components in combination with advanced control technology. The efforts are expected to increase energy production, reduce CAPEX and improve grid integration of wave energy farms, resulting in a reduction in the cost of energy of up to 30 per cent.

The project brings together renewable energy leaders from Sweden, Scotland and Portugal, including the utility company EDP, the European Marine Energy Centre (EMEC), WavEC Offshore Renewables, the University of Edinburgh, Research Institutes of Sweden (RISE), PMC Cylinders, GS-Hydro and CorPower Ocean.
