Science and engineering company Integral Consulting Inc. (Integral) was recently awarded two cooperative agreements by the U.S. Department of Energy (DOE) Water Power Technologies Office to support its marine and hydrokinetic projects.
The first contract will involve developing and field testing a standardized mapping tool set and protocol for assessing seafloor habitat conditions. Integral will use high-resolution sediment profile imaging and plan view (SPI/PV) image survey data combined with state-of-the-art acoustic seabed mapping techniques to generate detailed maps of benthic habitat conditions.
The second contract funds the measurement and characterization of device noise and environmental noise around offshore renewable energy projects. Integral will leverage an existing DOE-funded buoy platform to develop a cost-effective, compact array of sensors that will reduce the time and cost of collecting extended measurements of noise produced by marine and hydrokinetic devices. This acoustic measurement platform will also collect broadband acoustic data to facilitate detection of marine mammals and/or marine organisms.
“It is an exciting part of Integral’s business to be involved in this effort to advance the performance and environmental monitoring of wave and tidal energy systems,” said Integral President Bill Locke, P.E. “We look forward to working with DOE to improve and test these technologies.”
Integral’s SPI/PV system has been used across the globe to generate high-resolution images of seafloor conditions and biological communities. The award also includes funding to develop new hardware and software tools to streamline and standardize the delineation of seafloor conditions. Under the new DOE contract, image processing algorithms are being developed using a combination of open-source and commercially available software packages. The resulting data will inform siting and baseline studies as well as post-construction monitoring at marine and hydrokinetic sites.
The custom noise measurement platform will comprise a novel array of sensors capable of providing near real-time noise measurements along with location estimates of noise sources. The DOE acoustics award will support noise characterization of wave energy converters to enable future propagation modeling and remote detection of various modes of device operation.
