Purpose, Objectives, & Integration

The overall objective in the Reedsport PB150 Deployment and Ocean Test Project is to assemble and deploy a full scale 150kW PowerBuoy® for “relevant ocean testing” in the Oregon Territorial Sea, and collect detailed operating characteristics during two (2) years of operation

The project will address numerous challenges and knowledge gaps, such as:

– Assembly

• The capability to assemble the PowerBuoy needs to be investigated

• The contractor to accomplish final assembly must be selected

– Mobilization and Deployment

• A buoy the size of the PB150 has never been deployed off the western coast of the US

• New methodologies and processes need to be developed

• Cost impacts need to determined and reviewed for future buoys



The project will address numerous challenges and knowledge gaps (con’t):

– Two Years of Ocean Testing to Investigate

• Buoy Performance

• Electrical Output

• Energy Conversion

• Buoy Reliability

• Design Improvements

• Operations and Maintenance

– Environmental Studies

• Investigate the long term environmental impacts, if any, of deploying a buoy off the territorial water of Oregon

– Manufacturing Plans

• Determine the manufacturing methods for large scale manufacturing of PowerBuoys

• Lockheed Martin MS2 is performing this effort



Meeting the challenges above will demonstrate that the PB150 is a reliable, affordable and environmentally sustainable water power technology. This will help realize the benefits of domestic renewable energy production.

– Reduce the cost of assembly and deployment

– Advance the efficiency of the Power Take Off (PTO)

– Improve the rate at which subsequent buoys are manufactured and assembled

– Demonstrate the low environmental impact of deploying multiple buoys

– Confirm the design of the mooring system reliability and performance

– Determine a base line for improvement of the operation and maintenance costs for managing a wave energy farm

– Confirm that a PB150B2 can be economically viable in areas that have high costs for electricity.



This Reedsport PB150 Deployment and Ocean Test Project will provide the performance and reliability data required to develop manufacturing methodologies to maximize production and minimize cost for PB150 deployment in future buoy farms.

This project represents the initial phase of the first commercial wave park on the west coast of the US.


Technical Approach

The methods used:

• Assembly

– Produce PowerBuoy specifications and procedures that chronologically detail the sequence for assembly of the buoy components

– Conduct vendor evaluations to assess technical competency for assembly.

• Mobilization and Deployment

– Generate methodology to deploy a structure of this size

– Review the capabilities and experience of commercial sea merchants that have the deployment resources

• Two Years of Ocean Testing

– Collect performance and operational data

– Establish operation and maintenance schedule and requirements.


Technical Approach

The methods used (con’t):

• Environmental Studies

– In August 2010 OPT executed a stakeholder agreement to support the responsible phased development of a wave power station

– OPT filed stakeholders agreement and final license application with FERC

– All environmental studies will be conducted on a pre-deployment and post-deployment basis

• Sets up a base line to show the impact of a deployed buoy.

• Acoustic - Industry standard autonomous recorders will be used to monitor sounds at and from the buoy

• Electromagnetic Frequency (EMF) - Study naturally occurring field levels at various distances from the buoy


Technical Approach

The methods used (con’t):

• Manufacturing Plans

– Study the manufacturing methods to reduce multiple unit production costs ability of subsequent buoys using:

• Design for Manufacture (DFM)

• Design for Test (DFT)

• Lean Six Sigma

• Design for Six Sigma (DFSS)

• Design Guidance for Producibility (MIL-HDBK-727)

– Generate build schedules and preferred supplier lists


Technical Approach

The key issues being addressed during this Cooperative Agreement are:

• Assembly

– Review and analyze the assembly methods to discover cost reduction strategies.

• Mobilization and deployment

– Study the deployment of the PowerBuoy off the Oregon territorial waters in order to stream line future buoy deployments.

• Two Year Ocean Testing

– Generate a robust operational test plan

– Perform functionality testing

– Demonstrate target costs of electricity

– Reduce operational and maintenance costs


Technical Approach

The key issues being addressed during this contract are (con’t):

• Environmental Studies

– Determine the sea state baseline of the Oregon territorial waters prior to buoy deployment

– Review pre-deployment baseline against post-deployment test results

• Manufacturing Plans

– OPT and Lockheed Martin will perform analysis of buoy manufacturing methods for use in reduction of multiple unit production costs.

– Streamline the manufacturing and assembly process to reduce the overall buoy production cost


Technical Approach

Unique approach:

Assembly

• Developed vendor evaluation criteria and visited and reviewed various vendor facilities.

Mobilization and Deployment:

• Conducted Extensive Request for Bid process to find qualified candidate

Two Year Ocean Testing

• Produced a comprehensive test plan and procedure and schedule to monitor all aspects of a functional buoy


Technical Approach

Unique approach (con’t):

Environmental Study• OPT executed a historic agreement with 14 stakeholders to support

the responsible phased development wave power station

Manufacturing Plan• Utilize various manufacturing techniques including Six Sigma• Investigate the capabilities and limits of shipbuilders with regard to

manufacturing
