|Abstract: ||Marine pile driving during offshore wind farm construction may increase the anthropogenic
component of ocean ambient noise and has led to increasing concerns regarding its effects on the
marine fauna (receptors)1. In the case of many static offshore developments two commonly used
foundation techniques are tripod and jacket constructions involving installation of a series of smaller
diameter piles surrounding a central structure and mono-piles using a single larger diameter pile.
Pile installation itself may involve sequences of percussive piling at different hammer energies,
vibro-piling (more rapid, lower level vibrations) and drilling. In some cases all three techniques are
used on a single pile installation, with the construction phase lasting several hours for each pile, and
with perhaps 50 - 100 turbine supports in a typical windfarm development.|
