The European Clusters for Offshore Wind Servicing (ECOWindS) project builds on existing network within offshore wind energy to establish cluster cooperation in Offshore Wind Servicing (OWS) encompassing the industrial processes; assembly and installation of offshore wind turbines and operation and maintenance of wind turbines offshore.ECOWindS is a collaboration between research-driven clusters from South Denmark, East of England, North-West Germany and Møre, Norway , are- regions that are absolute hotspots for the world’s offshore wind industry. While the regions are characterised by complementary strengths and potential, they all face common challenges and bottle-necks that could best be dealt with within a cross-regional collaborative framework.The objective of the project is to develop and integrate regional OWS research agendas and smart specialisation strategies in a Joint Action Plan, enabling intensified intra- and interregional research and innovation-driven cooperation to ensure a more focused and efficient use of regional, national and EU Structural and RTD funds. Special will be devoted to how to better develop, include and utilize the competencies and knowledge of SMEs into innovation processes within the OWS sector.The ECOWINDS project runs through three successive and partly overlapping phases: (1) Analysis and integration of research agendas of actors in regional clusters; (2) Initiatives to improve integration: definition of a Joint Action Plan, including an International Cooperation Strategy and a Smart Specialisation Toolkit; (3) Measures towards the implementation of the Joint Action Plan.The implementation of ECOWindS and the exploitation of the results will foster smart, sustainable regional growth and job creation by contributing to drive down cost of energy from existing offshore wind farms and to half the cost of energy from new installations on comparable sites before 2020.
