This Guideline concerns underwater noise in relation to the construction of offshore wind in Danish waters. Technical methods are presented for performing numerical prognosis and measurements. Also, sets of acoustic criteria are stated for compliance. The latter include Permanent Threshold Shift (PTS), Temporary Threshold Shift (TTS), and behavioural impact. The acoustic criteria are based on auditory frequency weighting functions as relevant to species in Danish waters.
Impact pile driving as well as vibratory pile driving installation techniques are addressed, with separate adapted methods for modelling and measurements. Requirements for permitted use of an Acoustic Deterrent Device (ADD) are stated.
Concession Holder shall carry out a prognosis to estimate the environmental impact using the given sound source and propagation properties and calculate the acoustic metrics experienced by a receptor (marine mammal) while it is fleeing away from the noise source. The Prognosis must be .....
