Abstract
Jasco Applied Sciences was contracted by Statoil to conduct a continuous underwater acoustic recording programme in order to attempt to identify any discernible underwater acoustic signature from the HYWIND floating wind turbine and structure at the HYWIND test site to the West of Stavanger. In addition to recording at the HYWIND site, Statoil also requested that an identical recording configuration be conducted at a control site with comparable natural environmental conditions, 10km from the HYWIND test site (Figure 1). Both sites are relatively close (within several kilometres) to two local shipping fairways which pass closer to the HYWIND site than the control site.
Jasco completed the 150 day recording programme with 100% data capture in August 2011 and this report provides an initial analysis of elements of the acoustic data recovered from the recording programme.
The HYWIND structure and turbine, photographed during the deployment of the initial phase of recording are shown at Figure 2.
