1 New England Aqua Ventus I Project Overview Clarifying Questions 12 MW Demonstration Offshore Wind Farm Nov. 12,

2 Project Objectives 1. Construct New England Aqua Ventus I, a 12 MW pilot floating farm with two 6 MW direct-drive, permanent magnet turbines, to be completed by Demonstrate and de-risk VoluturnUS, a 6 MW semisubmersible floating turbine consisting of a unique concrete hull and an advanced composites tower. 3. Develop a potential Aqua Ventus II project 20+ miles offshore, which contemplates a 500 MW commercial farm. 2

6 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. Preparing VolturnUS 1:8 for Deployment, June 2 6

7 New Paradigm: Use Concrete Bridge Construction Industry to Construct Offshore Wind Farms New England Geographic Considerations Limited cost-effective heavy steel fabrication capabilities. $ /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. 7

May 2014 DOE selects 3 of 7 proposals to go from 50 to 100% design April 2015 May 2015 Mid 2016 September % design complete Begin construction of 12 MW farm, coordinated with fishing season First 6 MW turbine installed, coordinated with fishing season Complete construction of 12 MW farm, coordinated with fishing season 14

15 Environmental Monitoring and Outreach Started for Site 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/core sampling. Fish, bird, bat, benthic invertebrate and marine mammal pre-deployment monitoring accomplished. FONSI received for similar but smaller project in UMaine Deepwater Offshore Wind Test Site at Monhegan Island in the Gulf of Maine. 15

16 Test Site Statute Est 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 16

17 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., Vinalhaven cable) is 50 m on either side. 17

18 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 18

21 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. 21

28 K-12 Outreach In 2013 alone, over 1,500 K-12 students participated in our research, through in-classroom activities and tours of our facility. Over 1, students have participated in our STEM challenges, Wind Blade Challenge and DeepCwind s Windstorm Challenge. Students who compete and win are offered a paid internship at UMaine Composites Center upon enrollment at UMaine valued at over $20,000.

29 Undergraduate Education Over 120 students have worked directly for the offshore wind program. Since 2011, the DeepCwind Consortium Internship Program has funded nearly 20 full-time student employees each summer. Internship placements included UMaine Composites Center, SGC Engineering, Bath Iron Works, Emera Maine, Central Maine Power, Ashland, and more. In 2013, UMaine Composites Center had 157 undergraduate student employees during the academic year from diverse majors, and has employed over 1,000 students since opening. Eulan Patterson (pictured) worked at the UMaine Composites Center throughout his undergraduate career and now works as an electrical engineer with SGC Engineering, Inc.

30 Graduate Education Recent student theses: Kyle Warren, 2013: Resistence Welding of Thermoplastic Composites for Industrial Scale Wind Turbine Blades Heather Martin, 2011: Development of a Scale Model Wind Turbine for Testing of Offshore Floating Wind Turbine Systems. Recent student posters: Alex Coulling, 2013: Validation of a Fast Floating Wind Turbine Model Using Data from the DeepCwind Semi- Submerisble Model.
