VolturnUS: Why It Is Meaningfully Unique

• Capable of accessing high wind areas in deep waters off limits to traditional offshore wind installations.

• Utilizes commonly-available:• Materials and processes.

• Port infrastructure.

• Deployment Vessels.

• Ultra-lightweight composite tower with existing turbine designs reduces significantly hull weight.

• Designed for mass production and 100-year life-cycles.• Repowering in 20-year cycles by towing

platform to shore, replacing turbine, and redeploying the unit.

New Paradigm: Use Concrete Bridge Construction

Industry to Construct Offshore Wind Farms

New England Geographic Considerations

• Limited cost-effective heavy steel fabrication capabilities.

– $3000-5000/mt in China, does not include transportation costs.

– $8000/mt in GoM and $13,500/mt in New England.

• Limited or no access to large vessels/ floating cranes (required for a spar).

• Limited access to deep draft port facilities (required for a spar).

• Significant experience constructing prestressed concrete for heavy bridge construction.

Jamestown Bridge, RI

• Segmented Post Tensioned Girders

• 72ft wide deck• 4,980 ft.-long• T.Y. LIN Int.

Environmental Monitoring and Outreach Started for Site

UMaine Deepwater Offshore Wind Test Site at Monhegan Island in the Gulf of

Maine.

• Outreach with fishermen, other important stakeholder groups, especially re: cable route.

• Established by Maine Public Law 270 to allow accelerated permitting of hardware (60-days review period).

• Bottom characterization/coresampling.

• Fish, bird, bat, benthic invertebrate and marine mammal pre-deployment monitoring accomplished.

• FONSI received for similar but smaller project in 2011.

Test Site Statute

• Est. 2009

• Limit on Devices – each requires a permit

– Total 6 – wind or wave

• Limit on cable size 25 MW

• There is no “Restricted” zone in in test site

• DMR, Coast Guard, other agencies regulate

• Limited time permit – requires renewal

– First 5 years, subsequent every 3 years

– Environmental Monitoring Requirements

– Decommissioning Requirments

Responding to Concerns from Fisheries

• No effect on fixed gear.

• Geophysical surveys are being conducted to void hanging cable.

• Mobile gear types will have to lift their tows over the cableway.

• Team is conducting outreach to fishermen regarding tow routes.

• The “No fishing zone” on similar cables (e.g., Vinalhavencable) is 50 m on either side.

Providing Power to Monhegan

• A goal of this project is to provide 300 kW capacity to interconnect with the Monhegan Plantation Power District.

• We will make our best effort to coordinate through the Maine Public Utilities Commission and the utilities to provide the supply of energy to the island at no generation cost. T&D costs would be determined by the MPPD.

– All cable and connection equipment

– Supply power from turbines

– Supply power from mainland

• No fuel used to generate this power = avoid cost of diesel fuel and related transportation risks.

• Provide fiber optic cable for internet and telecommunication as necessary

Noise Difference Between PMDD Turbines

and Gear Box Turbines

• Quieter.

• “I can hear a lobster boat 3 miles from shore, so why won’t I hear your turbines?”

– You can hear a lobster boat on a clear day. The wind turbines won’t be spinning on a clear day.

– On a blustery day, you would not be able to hear the lobster boat. Similarly, you would not be able to hear the turbines spinning.

– A PMDD turbine would be quieter than, for example, the Fox Island turbines.

– When the turbines are spinning offshore, the diesel generators onshore won’t be running => noise reduction.
