Offshore Wind - DeepCwind Consortium

DeepCwind-Color-01

The DeepCwind Consortium’s ongoing mission is to establish the State of Maine as a national leader in deepwater offshore wind technology through a research initiative funded by the U.S. Department of Energy, the National Science Foundation, and others. The University of Maine-led consortium includes universities, nonprofits, and utilities; a wide range of industry leaders in offshore design, offshore construction, and marine structures manufacturing; firms with expertise in wind project siting, environmental analysis, environmental law, composites materials to assist in corrosion-resistant material design and selection, and energy investment; and industry organizations to assist with education and tech transfer activities.

The DeepCwind Consortium consists of approximately 30 members around the country, including two universities, two nonprofits, and a diverse group of industry leaders.


Task 1: Micrositing, Geophysical Investigations, and Geotechnical Engineering

The primary objective of micrositing, geophysical investigations, and geotechnical engineering was the characterization of the seafloor environment for turbine anchoring at the University of Maine Deepwater Offshore Wind Test Site in the Gulf of Maine. Activities coordinated geologic and geotechnical engineering information with the metocean forces assessed in the Offshore Turbine Testing, Monitoring, and Reliability task and assisted in design of efficient moorings and anchors for the floating offshore wind turbines under the Floating Turbines Design and Lab Testing task. An additional objective of this task was to provide site location documentation and address safety and navigation at the site once the turbines and moorings are installed.

Task 2: Study of Environmental/Ecological Impacts

Maine Public Law 270, which allowed the establishment of the University of Maine Deepwater Offshore Wind Test Site, required that the following state and federal agencies be consulted concerning environmental monitoring and planning of the test site:

  • Department of Inland Fisheries and Wildlife
  • Department of Marine Resources
  • Department of Conservation
  • Coast Guard
  • Army Corps of Engineers
  • NOAA Fisheries

These agencies required plans for siting, navigation, project removal, remedial action, and environmental/ecological monitoring. They also required reports and updates on site activities.

  • Micrositing and geophysical investigations activities
  • Bathymetric surveys
  • Survey to check for presence of historically significant resources
  • Site plan creation
  • Navigation and safety plan creation
  • Environmental/ecological monitoring activities

There will be wildlife-specific studies for:

  • Benthic Invertebrates
  • Fish
  • Marine mammals
  • Birds and bats
  • No live animals will be collected for the environmental monitoring efforts.

As part of the environmental/ecological monitoring plan that was part of the test site permit application, a review of the potential threats to marine life was considered and mitigation measures were designed. Potential areas of concern addressed in this report included the following:

  • Entanglement of marine mammals in mooring lines and structures.
  • Disturbance of migration and feeding areas.
  • Bird and bat strikes.
  • Attraction of fish or marine mammals to the platforms.
  • Interruption of wave energy direction and focus.
  • Human impacts.
  • Visual impacts.
  • Potential disturbance of historical or culturally significant areas.

All micrositing, environmental/ecological monitoring, and permitting activities were conducted from the start of the project in 2010 until the end of the project in 2012.

Task 3: Permitting and Policy

Under the recently enacted Maine Public Law 2009, Chapter 270 (LD 1465), the University of Maine Deepwater Offshore Wind Test Site is be located near Monhegan Island, an area selected by the state. This site was analyzed in detail through the state’s site selection process.

With Maine’s designation of the test site, the Permitting and Policy team secured specific permits for the proposed project from all applicable local, state, and federal permitting authorities. In conformance with the application requirements, to obtain a General Permit under LD 1465, the Permitting and Policy team, in conjunction with the Micrositing and Ecological Monitoring teams, submited a report to the required state and federal agencies describing:

  • Existing commercial fishing and other uses in the project area, as well as the marine resources.
  • A detailed monitoring plan of benthic invertebrates, fish, marine mammal, and avian wildlife.
  • Monitoring plan of ambient noise levels possibly associated with project construction and, if needed, any subsequent operations and avoidance and mitigation measures.
  • Navigation public safety plans.
  • Project removal plan.

The team worked to develop these plans in consultation with federal, state, and local agencies, as well as stakeholders.

Task 4: Floating Turbine Design, Material Selection, and Lab Testing

The primary objectives of the Floating Turbine Design task was to:

  • Partially validate the coupled aeroelastic/hydrodynamic models developed by NREL.
  • Optimize platform designs by integrating more durable, lighter, hybrid composite materials.
  • Develop a complete design of one or more scale floating turbine platforms, capable of supporting a wind turbine in the 10 kW to 250 kW range for deployment at the University of Maine Deepwater Offshore Wind Test Site.

Task 5: Offshore Turbine Testing, Monitoring, and Reliability

The Physical Oceanography Group (PhOG) at the University of Maine deployed and operated an oceanographic data buoy with real-time telemetry capabilities in the University of Maine Deepwater Offshore Wind Test Site offshore Monhegan Island. The ocean data buoy was deployed prior to the tank testing and remained in operation throughout the project period in order to monitor oceanographic, meteorological, and general environmental conditions. Monitoring emphasis was on wind speed and direction, visibility, directional waves, and water-column currents.

Task 6: Education and Outreach

The University of Maine, Maine Maritime Academy, and Northern Maine Community College developed several degree programs to create a trained workforce for the State of Maine. To ensure the community at large understands our research and development, the DeepCwind Consortium found numerous opportunities to share and discuss goals, activity plans, and the results of research. The consortium held public meetings to discuss the site selection for the University of Maine Deepwater Offshore Wind Test Site, presented at conferences within the state and across the country, and even taught an interactive wind-wave tank testing activity to over 500 K-12 students across Maine. These and other activities continued through the duration of the project.

Task 8: Fabrication and Deployment

UMaine and its subcontractors led the fabrication and deployment of the approximately 1/8 scale floating wind turbine platform. The deployment study sought to identify key deployment and installation factors. The performance data gathered from the 1/8 scale platform was used to further validate platform numerical models developed by NREL and others.
