Marine Hydrokinetic Implementation Study, PNSY

The U.S. Navy established an initiative to implement a tidal turbine off the coast of the Portsmouth Naval Shipyard (PNSY). Under our existing IDIQ contract, AECm was awarded the task order to complete a implementation study. The objective of this study is to quantify the hydrokinetic resource and to identify turbine systems that could be deployed in the local marine environment.

AECm partnered with the University of New Hampshire (UNH) Center for Ocean Renewable Energy (CORE) to measure the hydrokinetic resource and provided technical expertise on various turbine systems and configurations. As summarized in a final report, the project entails:

  • Preliminary Transect Surveys to Establish Hydrokinetic and Bathymetric Parameters
  • Long-Term Deployment of Acoustic Doppler Current Profilers (ADCPs)
  • Permitting and Regulatory Requirements Review
  • Local Mariner Impact Assessment (Commercial Shipping, Fishing, Recreation)
  • Marine Benthic Impact Assessment
  • Proposed Turbine Systems (Market Available) and Infrastructure
  • Electrical Interconnection Design
  • Cost Estimates
  • Three-Dimensional Renderings of the Turbine System

This preliminary assessment is intended to provide the essential information for a U.S. Navy determination to proceed with a tidal turbine system at the PNSY.
