- the emissions resulting from the specifically selected structural and equipment variant, in 
particular the type and scope of noise emitted into the water. 
These documents shall become an integral part of the approval in, as far as these accor 
dingly confirm, compliance with the respective incidental provisions. Reference is made 
here to the minimum requirements published by the BSH. 
Justification: 
The above directives serve to avoid both contamination and impairment of the marine environ 
ment and transport hazards in accordance with Art. 3 para. 1 SeeAnIV. As shown by the for 
mulation on emissions avoidance, it may be difficult to reconcile the requirements imposed in 
order to protect the natural environment and those for the safety of shipping. 
Whereas the requirement to provide a design with the greatest hull-retaining properties in the 
event of a collision between a ship and an offshore wind turbine serves to meet both the ob 
jectives defined in Art. 3 SeeAnIV simultaneously, in terms of light emissions, the safety requi 
rements for shipping and aviation limit the ability to completely avoid emissions during the 
construction and operating phases. 
As a result, there is a mandatory requirement to continuously optimise the installations in 
terms of ecological impact according to the latest technological findings and know-how to the 
extent that this is possible and reasonable based on indispensable safety measures. 
Linking this requirement to meet the state of the art is intended to ensure that the design and 
equipping of the system is able to avoid, resp. reduce any effects which cannot be foreseen 
with certainty at the time of approval, but which if they were to occur later would lead to the 
cancellation or revocation of the approval. In the event that pollution, noise and light emissions 
cannot be avoided, this directive incorporates the minimisation of the resulting impairments in 
accordance with the precautionary principle. Examples here include the development and use 
of deterrent measures against animal species that are negatively affected, the use of the best 
available and most naturally compatible traffic safety beacons in the form of a self-regulating 
system that flexibly adapts the light intensity to visibility conditions, the use of the most envi 
ronmentally friendly operating materials and the most comprehensive encapsulation system 
possible for pipes and containers that carry pollutants. 
The aforementioned purposes are also served by the specific requirements for configuring 
corrosion protection and the colour scheme of the systems. The requirement pertaining to the 
system colour scheme is intended to avoid any dazzle effect due to unnecessary reflections on 
the smooth system surfaces. With respect to the corrosion protection of offshore installations, 
the BSH has meanwhile published a set of minimum requirements which have been integrated 
into this standard. The absence of pollutants, in particular, shall also be accordingly demonst 
rated in an emission report. In as far as valid minimum requirements are in place at the time of 
ordering the structural components, these are to be complied with. The requirement on using 
oil-repellent coatings in the area that comes into contact with the sea surface ensures that 
drifting oil in the area of the project will not adhere to the components which would prevent 
the oil from being recovered. This is intended to avoid a situation in which oil stuck to the 
structure would be steadily washed out into the water over a longer period of time. 
In close connection with this, the anticipated emission of sound into the water should be men 
tioned as this is also subject to the prescribed minimisation requirement. The respective direc 
tive takes account of the possible exponential effect of noise emissions and how these can be 
avoided.
