Different types of jackets
Navantia has specialized in building these supports for offshore wind. They are structures of more than 60 meters that have to resist in the water a minimum of 25 years, subjected to adverse conditions of erosion and ocean currents. In addition, they must withstand the possible collisions of ships, preventing the wind turbine from falling while its structure is deformed to minimize damage to the impacted ship.
Since 2014, Navantia is working with Iberdrola Renovables in the manufacture of jackets with their respective piles, for the Wikinger park (Baltic Sea, Germany). 29 jackets and 116 piles have been manufactured, as well as the two topside modules for the electrical substation.
Navantia has also built four jackets and their corresponding piles for Siemens Wind Power. The structures were destined to the demonstration park of Nissum Bredning, located on the north-western coast of Denmark, in the North Sea, near the port of Thyborøn.
The Nissum Bredning (NBV) project is 55% owned by Nissum Bredning Vindmøllerlaug I / S and 45% by the local energy company Jysk Energi A / S. It is subsidized by the Danish Ministry of Energy and is considered an excellent opportunity to test, in a controlled and small-scale environment, new key technologies in the field of offshore wind.
