Part A - Framework conditions 
Observers in radar surveys must have received instructions in radar technology and optimal 
operation of radar equipment from an experienced radar observer (Hüppop et al. 2002). 
The interpretation of bat call recordings and the identification of species are to be carried out 
by persons with long-standing experience in the bio-acoustic analysis of bat calls. 
Proof of adequate qualification in the field of noise and vibration has to be provided (e. g. ac 
creditation according to DIN EN 45001 for noise and other measurements of wind turbine 
emissions). 
For the purpose of quality assurance, the submission of expert reports (Section 13) to the 
planning approval/approval authority must be supplemented by documentation of data col 
lection and evaluation that is both reasonable and focused on features of conservation inter 
est. 
7 Decommissioning phase 
The wind turbines including their foundations have to be removed completely, with sub 
sequent onshore disposal. 
In principle, the monitoring requirements during this phase correspond to those in the con 
struction phase as specified in the StUK. Possible environmental impacts depend mainly on 
the dismantling techniques used, which are expected to undergo major technical improve 
ment during the coming decades when numerous oil and gas platforms are due for decom 
missioning. Therefore, the final scope of standardised monitoring will be determined at a later 
date. Should the need arise in the meantime, the planning approval/approval authority shall 
establish a study framework for corresponding monitoring measures in the specific case. 
8 Further studies and analyses 
In addition to the studies described in the StUK at hand, further requirements may result from 
other regulations as well as from the incidental provisions of the respective planning approval 
decision/the respective permit. In particular, the standard at hand is closely linked to the other 
standards published by the BSFI (Standard “Design of Offshore Wind Turbines” (BSFI 2007), 
Standard “Ground Investigations for Offshore Wind Farms” (BSFI 2008)); explicit reference is 
made here to their content (surveys in the context of collision and risk analysis, environmental 
impact studies in co-ordination with the design basis and preliminary draft, due consideration 
of the planned noise reduction measure when drawing up the basic design, etc.).
