150 CUMULATIVE EFFECTS
13. Cumulative effects
13.1 Why cumulative effects?
Directly south of the wind farm described in this document,
in the German economic zone, another farm is
planned, consisting of 80 turbines, whereof 53 3,6 MW
turbines and 27 5 MW turbines. The towers of the 3,6
MW turbines will be approximately 80 meters high
and the distances are planned at 450 x 750 m. The towers
of the 5 MW turbines are expected to be approximately
95 meters high and the distances are planned
to be 600 x 900 m. The permit application for this
development has already been submitted and a permit
is expected early 2005. Offshore Ostee Wind AG, who
is in the same group of companies as Sweden Offshore,
runs the project.
As it is not unlikely that both developments will be
granted permits, it is of interest to study the consequences
that the development of both sites would have.
At the consultation meetings, an account of the cumulative
effects for birds, salt-water mix as well as the
landscape picture has been requested, and the studies
have therefore been limited to these three effects.
Furthermore, the cumulative effect regarding shipping/navigation
and risks has been dealt within short
by the SSPA in the risk analysis that the company has
made (Attachment 12.2).
Any impact of importance on other ”objects” (e.g.
mammals, vegetation and seabed creatures) due to
cumulative effects are not expected.
13.2 Birds
According to the study by Jan Pettersson, it is estimated
that 10 water fowl will collide with the Swedish
turbines at Kriegers Flak during the spring migration
and 38 during the autumn migration. Corresponding
numbers for the German turbines at Kriegers Flak are
5 and 18 respectively. This is assuming that the behaviour
of the water fowl when encountering the turbines
is the same as in Kalmarsund and that the night track
