    UMaine's offshore wind buoy is ready for real test - in the ocean

    The system will be used to track wind speeds at the height of offshore wind turbines to determine the suitability of sites for wind farms.

    ORONO — A data-collection buoy that can be plopped in the ocean and used to determine the suitability of remote locations for offshore wind farms is ready for real-world testing, the University of Maine announced Friday.

    The university's advanced composites center worked with private industry partners to create a buoy-based system that utilizes a laser system to track wind speeds 400 to 500 feet overhead, the height of offshore wind turbines. The data is relayed to scientists on shore via wireless technology.

    The university said the devices would allow wind power companies to assess potential offshore wind sites for which data is not currently available.

    The futuristic-looking buoy will be deployed initially alongside a one-eighth scale offshore wind turbine prototype that will be deployed in about a week off the coast of Castine.

    It utilizes a light detection and ranging system, known as LIDAR, which collects wind speed data by sending a laser beam into the sky. Reflected light in the atmosphere is used to determine wind conditions.

    "Floating LIDAR technology, once fully validated, will provide us with a cost-effective method to assess the wind resource in areas traditionally off-limits to offshore wind developers," said Habib Dagher, director of UMaine's composites center.

    The device, formally unveiled on Friday, was created by a partnership that included NRG Systems Inc., AWS Truepower LLC and Leosphere SAS, along with the university's composites center and its Physical Oceanography Group, which develops and operates real-time ocean observing systems.
