According to the operator EnBW, the German Chancellor has also announced her attendance at the official commissioning on 2 May in Zingst. The "Baltic 1" offshore wind farm is located 16 kilometres north of the Darß/Zingst peninsula on an area of around seven square kilometres. The 21 wind turbines have a total output of around 50 megawatts and generate 185 gigawatt hours of electricity per year for around 50,000 households. Since September 2010, 21 wind turbines and the substation of the offshore wind farm have been erected and subjected to thorough testing. Trial operation has been underway since the beginning of April.
To the Labelling of the individual systems and to the Establishment of a safety zone for shipping has the Stralsund Waterways and Shipping Office The Federal Maritime Administration (BfS) has issued two corresponding notices to mariners:
Labelling:
The Baltic I offshore wind farm was put into operation within the above-mentioned area (west of the Plantagenetgrund). There is a safety zone of 500 metres around the wind farm in which special navigation requirements apply.
A general ruling was issued by the WSD North in accordance with the KVR.
There are 21 wind turbines and one substation platform (USP) within the wind farm, which are labelled with the object designations B0 (for the USP) and B1 to B21 (corresponding to the number of the wind turbine). The WTGs are of tubular construction with a diameter of 4.20 metres at the waterline. The hub height above mean water is 67.00 metres. The blade tips of the rotor reach a maximum height of 112.00 metres.
The USP has an extension of 30.00 x 23.00 metres and also stands on a tubular base, reaching a maximum height of 35.00 metres to the upper edge of the closed superstructure.
All objects are painted yellow up to a height of 17.00 m above mean water to make them easier to recognise during the day. Three to four panels each show the object identification B0 to B21 in a character size of 0.60 m from all approach directions. These signs are backlit at night. In addition, the object designation is shown during the day in 1.00 m high black letters on a yellow background above the maintenance platform.
At night, all objects are marked with close-range lighting, which only emphasises the outline of the turbine when approached directly. From a greater distance, yellow beacons with a nominal range of 5 nautical miles (5 nm beacons) act as navigation markers, each of which is visible from the periphery of the wind farm.
These 5-sm lights are installed at the objects of the corner positions of the wind farm (Significant Peripherical Structure - SPS) with the identifier
Ubr Y (3) 16 s= 6.5 + (1.5) + 2.5 + (1.5) + 2.5+ (1.5) s operated.
The 5-sm lights with the code Blz Y 4s = 1 + (3) s are operated on the remaining systems of the outer contour.
All 5-sm lights are installed at a height of 16 metres above mean water.
On the roof of the nacelles, red aviation lights visible from all sides at a height of 72.00 metres are operated on all WTGs (objects B1 to B21)
Identifier Blz R (2) 4s = 1 + (0.5) + 1 + (1.5) s
Two of these lights are arranged on each wind turbine in such a way that at least one light is visible regardless of the position of the rotor blades. The nominal range of the aviation markings is therefore 5 to 6 nm. The yellow 5-sm beacons and the red aviation beacons of all objects are synchronised with each other so that the wind farm can be perceived as a coherent structure at night.
For the corner positions of the wind farm, the following positions are virtually labelled by a transmitter on the transformer platform as OFFSHORE PLATFORM with the following text identifier
- 54° 37,9879' N; 012° 41,7172' E - "WIND FARM BALTIC1NE"
- 54° 36,7689' N; 012° 37,7677' E - "WIND FARM BALTIC1NW"
- 54° 34,9886' N; 012° 37,7400' E - "WIND FARM BALTIC1SW"
The cardinal and special area buoys laid out in the course of securing the construction site for the construction of the Baltic 1 offshore wind farm and published with BfS (T)009/2010 will be withdrawn without replacement in the 18th calendar week.
Safety zone:
In accordance with Section 7 (1) of the Ordinance on the International Regulations of 1972 for the Prevention of Collisions at Sea of 13 June 1977 (VO-KVR, Federal Law Gazette I, p. 813), last amended by Article 2 of the Ordinance of 28 June 2006 (Federal Law Gazette I, p. 1417), a safety zone of 500 m distance extends around the EnBW Baltic 1 wind farm, the boundary of which is described below:
500 m radii around the following corner points of the wind farm:
- SW 54°34.9886'N 012°37.7400'E
- NW 54°36,7689'N 012°37,7677'E
- NE 54°37,9879'N 012°41,7172'E
and the connecting straight lines between these outer radii are characterised by the following points:
- Boundary point 1 54°38,2275'N 012°41,4994'E to
- Boundary point 6 54°37,0082'N 012°37,5500'E;
- Boundary point 2 54°37,8250'N 012°42,0855'E to
- Boundary point 3 54°34,8258'N 012°38,1087'E
- Boundary point 4 54°34.9925'N 012°37.2769'E to
- Boundary point 5 54°36,7727'N 012°37,3040'E
Upon commissioning of the wind farm, the following order shall be issued in deviation from Section 7 (2) with regard to travelling through the "EnBW Baltic 1 wind farm" safety zone in accordance with Section 7 (3):
Vehicles under 24 metres are not permitted to enter the safety zone:
- with visibility below 1000 m,
- in the dark,
- with wind forces of 6 Bft. and more and
- for vessels fishing with bottom nets or trawls.
Furthermore, it is not permitted to moor or tie up to the wind turbines and the transformer platform or to anchor. Vehicles and equipment used to repair and equip the project or to fulfil and monitor compliance with the contractor's obligations are exempt from this.
