EnBW Baltic 1: How a wind farm is constructed on the high seas
Preparation: A traffic management ship arrives at the construction site and monitors the traffic at sea. The construction office is procured and the employees gradually commence their work.
Groundbreaking ceremony: official start of construction at sea. The components for the turbines that were manufactured on land are now successively installed at the offshore construction site.
Foundations: The special ship Sea Worker brings the foundations consisting of monopiles and transition pieces to the construction site.
Special ship: The Sea Worker anchors the monopiles, steel foundations around 37 m long, into the seabed using a powerful pile driver.
Colossus: Transition pieces are used to connect the foundations and the wind power plants together.
Transfer: The floating crane Matador (middle) transfers the 430 t monopile for the substation to the installation ship Sea Worker (right).
Precision work: The floating crane has delivered the 900 t substation to the construction site and will place it onto the transition piece in the evening.
Basis: The yellow crowhorn serves as the supporting surface for the substation and is fitted to the transition piece at the construction site.
Cable: Divers guide the sea cable upwards from the seabed through the transition piece. The cable will later be connected to the wind power plant.
Tower construction: The tower for the first wind power plant rises up piece by piece.
Raising the star-shaped rotor: The special crane has mounted the rotor with its 45m long rotor blades to the nacelle.
Precision landing: The first star-shaped rotor has been raised and the first wind power plant is installed.
For now the first turbine stands alone on the high seas...
...but the remaining 20 turbines will also soon be installed – EnBW Baltic 1 has been generating enough electricity for an aggregate of 50.000 households since 2010.
Wind power today and tomorrow
