140 CONSEQUENSES OF THE WIND FARM
It is also important to describe how the structure
will be experienced from close distance, from people
in passing boats. 10 000 ferries annually pass west and
east of Kriegers Flak. The passengers on these ships
will be able to see the wind farm after a journey of 20
– 25 km from Trelleborg at a distance of 5 – 10 km. A
vertical element in an open landscape dominated by
horizontal lines will create a big contrast. From close
distance, the wind turbines will, therefore, be dominant
(see picture in Chapter 12.8.1). It is, however, probably
difÞ cult to estimate the height of the turbines as there
is nothing else to relate to. It is likely that the turbines
will be interpreted as lower than they are. Whether
passengers will Þ nd the wind farm as interesting or
disturbing in relation to the open sea and other objects,
for example boats, is subject to individual judgement.
b) Night time
Deutsche Wetterdienst also investigated whether different
strengths of light will be visible at distances of
30 and 40 km. The result was that neither the strengths
1 500, 1 600 or 2 000 cd was visible at these distances.
The regulations surrounding hazard lighting are
currently under review on an international basis and
no knowledge of the strengths of light to be used in the
ASSESSMENT CRITERIA
Very big impact
• The structure dominates greatly and is in big contrast
to the surrounding landscape – permanent change, >
a generation.
• The structure causes big physical change that greatly
infl uences the ability to orientate, views, landmarks
etc. – permanent change, > a generation
Big impact
• The structure dominates heavily or is in big contrast to
the surrounding landscape – temporary, < a generation
• The structure causes big physical change that greatly
infl uences the ability to orientate, views, landmarks
etc. – temporary, < a generation.
Reasonable impact
• The structure has a certain dominance over or is in
contrast to the surrounding landscape – temporary,
less than a decade
future are therefore currently known. It is therefore
not currently possible to visualise how and if the wind
farm will be experienced from shore.
The working ships that will be used in the area during
the construction and dismantling phases will not be
visible from shore.
Summary
During day time, the wind farm will very seldom be
visible from shore. When it is visible, it will be seen as
a long line of small, weak, white pins at the horizon.
Whether the wind farm will be visible from shore
during night time, is currently not possible to say.
Seen from the sea, i.e. from a closer distance, the
wind farm will dominate the landscape. How this is
apprehended depends on the viewer.
All visualisations made are gathered at the end of
this document and in Attachment 11.1.
12.6.2 Mitigating measures
To the extent possible, the colour on the wind turbines
will be the one least visible.
12.6.3 Assessment
• The structure causes physical changes that impact the
ability to orientate, usual fare ways, landmarks etc. to
a lesser extent – temporary, less than a decade
Small impact
• The structure has a subordinated impact on the surrounding
landscape and/or the contrast effect of the
structure is small
• The structure causes physical change that, to a lesser
extent, impact the ability to orientate, usual fare ways,
boundaries, landmarks etc.
Minor/no impact
• The structure harmonises with the surrounding landscape
• The structure cause no physical changes
