De Opdrachtomschrijving

Europe’s energy transition is among the greatest challenges of our time. Its goal: To make Europe the first climate-neutral continent by 2050 at the latest. The Netherlands and Germany have therefore set themselves ambitious goals to expand offshore wind energy: as early as 2030, Germany and the Netherlands want to reach a capacity of 30 and 22.2 Gigawatts, respectively. Energy from offshore wind farms in the European powerhouse North Sea will play in this a crucial role. TenneT guarantees that this energy will reach the mainland

  • and in the most environmentally friendly way possible. That is why we have developed the 2GW program with a unique transnational approach. And thus increase the pace and efficiency of the energy transition. Unit offshore: Offshore is responsible for the development, construction, and management of the offshore electricity grid. With the North Sea as the green engine of the energy transition, Offshore plays a clear and vital role within TenneT’s organisational structure. The Offshore division manages the entire lifecycle of all TenneT offshore installations, from development and realisation to maintenance and handover to the Operate division. A crucial task is the construction of 2 GW offshore ‘sockets’, which collect and transport generated wind energy to the mainland. For more information about the TenneT offshore projects: https://www.tennet.eu/nl/themas/offshore Tasks The Offshore Installation Manager oversees operations on the Dutch offshore assets, including the health, safety and welfare of all crew, as well as environmental aspects.
