Assessing underwater noise levels during pile-driving at an offshore windfarm and its potential effects on marine mammals.
Marine renewable developments have raised concerns over impacts of underwater noise on marine species, particularly from pile-driving for wind turbines. Environmental assessments typically use generic sound propagation models, but empirical tests of these models are lacking. In 2006, two 5MW wind turbines were installed off NE Scotland. The turbines were in deep (>40m) water, 25km from the Mora...
متن کاملOn the estimation of prediction accuracy in numerical offshore pile driving noise modelling
Due to the massive, worldwide increase in the number of constructed offshore wind farms, the ecological impact of construction sites has become an important issue. Hereby, the topic of sound radiation from the needed pile driving procedures for the pile foundations of the turbines has gained a lot of attention lately. Therefore, several numerical models are currently developed to accurately pre...
متن کاملObserved increases in offshore pile driving resistance
This paper presents 53 well-documented cases of the short-term set-up of open-ended steel pipe piles driven at two fields in the North Sea. Increases in soil resistance during driving (set-up) were observed when pile driving was re-started after delays typically ranging between 24 h and 100 h. The soil encountered at the sites consisted of overconsolidated sands and clays, where the clays varie...
متن کاملModeling of offshore pile driving noise using a semi-analytical variational formulation
Underwater noise radiated from offshore pile driving got much attention in recent years due to its threat to the marine environment. This study develops a three-dimensional semi-analytical method, in which the pile is modeled as an elastic thin cylindrical shell, to predict vibration and underwater acoustic radiation caused by hammer impact. The cylindrical shell, subject to the Reissner–Naghdi...
متن کاملEffects of Noise on Sound Perception in Marine Mammals
For marine mammals, auditory perception plays a critical role in a variety of acoustically mediated behaviors, such as communication, foraging, social interactions, and avoidance of predators. Although auditory perception involves many other factors beyond merely hearing or detecting sounds, sound detection is a required element for perception. As with many other processes, sound detection may ...
