Wave power developer Ocean Power Technologies Inc. announced Oct. 2 it received $1.9 million from the United States Navy for its ongoing contract to deploy wave energy units off the shore of a U.S. Marine base in Hawaii.
The additional contract award will support testing and monitoring of the next PowerBuoy wave generating system to be deployed one mile off the coast of the Marine base at Kaneohe Bay on Oahu, Hawaii. (HNN 9/20/07) PowerBuoy devices generate power by moving up and down on a central spar as waves pass by.
Work has been under way for construction of a 40-kW PowerBuoy at the site. The unit is expected to be deployed by the end of the year. The performance of a previous buoy deployed at the site is being assessed, with general findings that power generated was in accord with expectations for the site.
OPT eventually is to install, test, and grid-connect multiple PowerBuoy units at the site. The project is to employ Hawaiian subcontractors for the installation, testing, and servicing of the systems.
OPT previously received a $1.7 million contract from the Navy in an ongoing relationship to provide a PowerBuoy as an autonomous unit to power the Navy’s Deep Water Acoustic Detection System, which has prospective applications including vessel tracking for homeland security.
During that contract, the Navy will test the PowerBuoy as an energy source for the unmanned sensor network. In addition, OPT is to support the Navy’s ocean test procedures in areas of mooring design, at-sea operations, and deployment.
