GE Researchers Unveil 12 MW Floating Wind Turbine Concept

GE Researchers Unveil 12 MW Floating Wind Turbine Concept
  • Highlights $4 MM Advanced Research Projects Agency-Energy (ARPA-E) ATLANTIS project during ARPA-E’s Virtual Innovation Summit
  • Project involves the design and development of optimized controls that could enable future offshore turbines 35% lower in mass compared to current designs for floating offshore turbines
  • Floating Turbines would open up possibility for offshore installations at depths beyond >60m
  • Would dramatically expand potential of US offshore wind resources to more than 7,000 TeraWatt hours (TWh) per year, nearly double the total annual US energy consumption of 4,000 TWh

NISKAYUNA, NY – May 24, 2021 –GE researchers unveiled details of an ongoing two-year, $4 MM project through the ARPA-E’s ATLANTIS (Aerodynamic Turbines Lighter and Afloat with Nautical Technologies and Integrated Servo-control) program to design and develop advanced controls to support a 12 MW Floating Offshore Wind Turbine. GE is partnering on the project with Glosten, one of the leading design and consulting firms in the marine industry, and the developer of the PelaStar tension-leg platform floating wind turbine foundation.

The Floating Wind Turbine project is one of several cutting-edge energy technologies GE Research is featuring at the annual ARPA-E Innovation Summit, which is being held virtually this year from Monday, May 24-27.

Rogier Blom, a Senior Principal Engineer in Model-Based Controls and the project’s principal investigator, says the enormity of building a floating platform that can support a structure as massive as an 850+ ft. offshore turbine cannot be understated, stating, “Designing a floating turbine is like putting a bus on a tall pole, making it float and then stabilizing it while it interacts with wind and waves. Doing this well is both a design and controls challenge.”

“Through our ATLANTIS project with ARPA-E, we will be concurrently designing the controls system with the design of the floating structure itself to advance Floating Offshore Wind Energy toward becoming a future commercially viable solution.”

Accelerating the development of new technologies to promote the future of floating offshore wind energy is the key objective of ARPA-E’s Atlantis program. By coupling a 12 MW GE turbine with Glosten’s tension leg platform technology, the team has taken on the challenge of designing a light-weight Floating Turbine with up to 35% less mass in the tower and the floating platform. This is expected to result in a very significant reduction of the resulting Levelized Cost of Energy – LCOE – of the electricity generated with this turbine. The core principle that makes this possible is co-designing the controls system with the tower and floating platform.

Ben Ackers, Vice President and Principal in Glosten’s Ocean Engineering and Analysis group commented on the collaboration between GE and Glosten. “We excel when we engage across all of the active disciplines and components as we optimize our floating structures for a full system solution. Collaborating closely with GE gives us another layer of detailed engineering design input beyond the standard drivers of site conditions, construction cost, schedule, and the resulting LCOE. This is the cooperation needed to bring floating wind to technical and commercial success.”

Between GE Research and Glosten, the joint research team brings decades of expertise in all areas of technology involved in carrying out the mission of our project, including turbine controls, structures, aero engineering, naval architecture, and hydrodynamics.

Blom noted that enabling floating offshore wind would dramatically expand the power generation potential of offshore wind power.

“With GE’s Haliade-X, the world’s most powerful offshore wind turbine built to date, we’re just beginning to tap into the future promise of offshore wind power in Europe, the US, and other parts of the globe, Blom said. “Today, these fixed-bottom wind turbines are limited to depths of 60 meters or less. With floating turbines, we would be able to dramatically expand the reaches of offshore wind power to areas with water depths of 60 meters or greater.”

According to the National Renewable Energy Lab (NREL), the introduction of floating turbines would dramatically expand the potential of US offshore wind resources to more than 7,000 TeraWatt hours (TWhs) per year, nearly double the total annual US energy consumption of 4,000 TWh.
