The Maine Aqua Ventus Project
Diamond Offshore Wind, RWE Renewables join the University of Maine to lead the development of the Maine floating offshore wind demonstration project
The University of Maine will collaborate with New England Aqua Ventus, LLC (NEAV), a joint venture between Diamond Offshore Wind, a subsidiary of the Mitsubishi Corporation, and RWE Renewables, the second-largest company in offshore wind globally, to develop UMaine’s floating offshore wind technology demonstration project off the coast of Maine.
As the developer, NEAV will own and manage all aspects of permitting, construction and assembly, deployment, and ongoing operations for the project. UMaine’s Advanced Structures and Composites Center will continue with design and engineering, research and development, and post-construction monitoring.
Maine’s manufacturing heritage was built on local power. Maine has more than 156 GW of clean offshore wind energy that is renewable, environmentally responsible, and within our reach. Successfully harnessing offshore wind will contribute to the transformation of Maine’s energy sector to renewable sources, and keep our energy dollars in our state.
UMaine economist Todd Gabe estimates that the New England Aqua Ventus I project will produce nearly $200 million in total economic output, supporting jobs during the construction period and ongoing operation and maintenance jobs during the project duration. Jobs range from construction workers and technicians to ship captains and professional engineers. Learn more, here.
We are committed to responsible offshore development in a manner that includes involvement and guidance by local communities and marine users. Aqua Ventus is committed to not developing a larger scale project within 10 miles of an inhabited island or peninsula along the coast of Maine.

Commitment to Island and Coastal Communities
Aqua Ventus is committed to:
- Frequent and transparent outreach with communities and existing marine users
- A single turbine demonstration project within the University of Maine Deepwater Offshore Wind Test Site at Monhegan Island for evaluating technology, monitoring the environment, and developing best practices for coexistence with marine users
- An emphasis on local economic development opportunities
- Future use of UMaine’s VolturnUS floating technology only in commercial projects located more than 10 miles from Monhegan, other inhabited Maine islands, and the mainland coast.
- Responsible offshore wind development in a manner that includes involvement and guidance by local communities and marine users.
- Aqua Ventus understands the economic and cultural significance of our coastal and island communities and neighboring waters. Our measured and informed approach to offshore wind development is intended to minimize potential risks or adverse effects on existing industries and the natural environment.
About Aqua Ventus
New England Aqua Ventus I (the Project) is an 11 Megawatt (MW) floating offshore wind demonstration project to develop a clean, renewable energy source off Maine’s shores.
This demonstration project is unique in that: it will mount a 11 MW wind turbine to a floating semisubmersible concrete hull called the VolturnUS, designed by the Advanced Structures and Composites Center at the University of Maine. The patented VolturnUS hull technology has been demonstrated in independent reports to reduce the cost of offshore wind. The turbine is held in position in the ocean by three marine mooring lines securely anchored to the seabed, and connected by subsea cable to the Maine power grid by subsea cable.
The project goals are to: demonstrate the innovative design of the VolturnUS with a full-size offshore wind turbine, work with local contractors and manufacturers to generate local economic benefit, create and keep Maine jobs in Maine, and provide renewable energy now and in the future.
Harnessing the clean, renewable wind energy from our deep ocean waters will contribute to the transformation of our energy sector to renewable sources, and keep our energy dollars in Maine.
