(Portland --) Maine Marine Composites, LLC (MMC) announced successful completion of a hydrodynamics analysis project for Maine-based Ocean Renewable Power Company (ORPC). According to Richard Akers, CTO of MMC, “The transient forces encountered during deployment of ORPC’s TidGen™ and OCGen™ tidal turbine generator units will be extreme, and the goal of this project was to better understand these forces.” MMC performed frequency-domain analyses of the dynamic characteristics of the tidal turbines by using the AQWA potential flow program from ANSYS to predict how turbine housing structures would respond to a range of current and wave conditions. ORPC will use the response information from these analyses for mooring system design and for structural analysis of the tidal turbine framework.
Founded in 2006, Portland-based Maine Marine Composites LLC provides advanced engineering and analysis services for projects in the marine environment. MMC provides analysis services for hydrokinetic energy converters such as wave, tidal and river energy converters. Our design services can aid the operators of energy converters in tasks such as site selection for maximum production and minimum environmental impact in extreme ocean environments. Further, the company delivers design and analysis services to aid naval architects, including the prediction of boat performance, resistance and ergonomic ride quality, as well as full service boat design.

Since 2004, ORPC has been developing breakthrough technology and eco-conscious projects that use ocean and river currents to produce clean, predictable electricity without using dams. ORPC develops its proprietary power systems and project sites simultaneously with the goal of deploying tidal turbines in North America’s best tidal energy sites when those sites are licensed and ready for production. In February 2012, federal regulators granted ORPC a license to install a 300-kilowatt tidal power project in Cobscook Bay, near Eastport and Lubec, Maine. The company will likely be the first in the country to operate a long term, commercial tidal energy project connected to the power grid. For more information on ORPC visit http://www.orpc.co.
