The Real Test for Floating Offshore Wind Turbines Amid Policy Headwinds
Floating wind turbines are producing power at demonstration sites across Europe, Asia, and in Maine, but plans for larger commercial projects have lagged behind early projections amid rising engineering challenges, project delays, and policy headwinds, Maine Morning Star reported on October 20, 2026.
Building Floating Turbines Farther From Shore
Picture a buoyant triangular steel or concrete platform roughly the dimensions of a baseball field. Mount a wind turbine that exceeds the height of the London Eye above it, secure the seabed with mooring lines alongside power lines running to the electrical grid, and your floating wind setup is complete. This technology allows developers to capture high winds farther out at sea where waters are too deep for fixed-bottom structures. In places like California, where the coastal shelf slopes steeply, floating wind has been treated as the primary option.
Yet keeping buoyant, vibrating skyscrapers stable in deep ocean waters creates severe engineering challenges and high costs. A wind trade association warned recently that the commercialization window for the technology cannot be assumed to remain open indefinitely, pointing to delays and policy shifts that have slowed down projects of 10 or more turbines.
Maine Tests a Plus-Sign Platform Design
Habib Dagher, who heads the Advanced Structures and Composites Center at the University of Maine, traces the state’s push into floating wind back to the 2008 global energy crisis, when heating fuel prices spiked above $4 a gallon. Today, the state faces a similar crunch with fuel surpassing $6 a gallon. Following a 2010 bond measure backed by nearly 60 percent of voters, the university developed a concrete, plus-sign-shaped platform supporting a 108-foot-tall turbine. Cadets from the Maine Maritime Academy towed the quarter-scale model to the waters off Castine in May 2025.
Anthony Viselli, chief engineer at the center, noted that Maine serves as a natural testing ground because the water depths are manageable, the wind resource is strong, and the waves remain moderate. Dublin Offshore, an Irish mooring line technology maker, is testing a shock-absorbing device on the Castine model. Darren Hayes, technical director at Dublin Offshore, called the demonstration the critical final step to deliver evidence that developers and investors need.
Addressing Stakeholder Concerns in the Gulf of Maine
In 2021, Maine established the Offshore Wind Research Consortium to study how offshore wind projects affect coastal communities and fisheries. Alison Bates, a co-chair of the consortium and a professor at Colby College, explained that the group prioritizes research to build a shared understanding among members with diverse backgrounds. To see an operating installation featuring five turbines situated east of Aberdeen, the consortium provided financial support for representatives of Maine fisheries to travel to Scotland.
Terry Alexander, a commercial ground fisherman and co-chair of the consortium, stated that gathering baseline data before turbines are installed remains essential for tracking changes to the ecosystem. Meanwhile, the state signed a lease with the Bureau of Ocean Energy Management in 2024 to build a research array of 10 to 12 full-sized platforms. Last March, however, the developer suspended contract negotiations for a power offtake agreement because energy market conditions changed, leaving the project in limbo.
Federal Targets Meet Policy Reversals
In 2022, the Biden administration launched the Floating WindShot with a goal of slashing electricity costs from the technology by 70 percent. Liz Klein, director of the Bureau of Ocean Energy Management during the final two years of the Biden administration, noted that the U.S. benefited greatly from international partnerships and shared research. By the end of that administration, several commercial-scale floating offshore wind leases had been auctioned off in the Gulf of Maine and off the California coast.
High costs continue to weigh on the sector. Harrison Sholler, a wind energy analyst at Bloomberg NEF, pointed out that the levelized cost of electricity from new floating wind projects was about double that of fixed-bottom wind when the WindShot was announced. Technical hurdles involving dynamic power cables and offshore substations remain unsolved. Building specialized ports with large staging areas immediately adjacent to deep water carries a price tag upwards of $1 billion each.
Regulations and political priorities shifted abruptly under President Donald Trump. Last December, the administration attempted to halt five under-construction fixed offshore wind projects over unspecified national security concerns, and courts rejected the moves while developers absorbed heavy daily losses. The federal government has also effectively ended further offshore leasing, buying back existing leases and redirecting investments toward gas power plants and export terminals. Interior Secretary Doug Burgum stated that companies are shifting investments back toward dependable, secure energy infrastructure. At least nine states have filed lawsuits seeking to invalidate the lease buybacks. The administration also cancelled grants for wind port construction in California and Salem, Massachusetts. Transportation Secretary Sean Duffy defended the cancellations by stating the administration prioritizes real infrastructure improvements over expensive wind projects. Financiers and developers now view the United States as a politically risky market for offshore wind development.
