Engineers at the University of Queensland have cut floating wind turbine costs by 40 percent.
Their new structure design achieves that saving compared with similarly sized existing platforms.
The findings were published this week.
Associate Professor Wenhua Zhao at UQ’s School of Civil Engineering led the work.
He used a geometry-based approach and tested the design through deep ocean and extreme weather simulations.
Floating offshore wind is one of the most promising untapped renewable energy sources.
Fixed-bottom offshore turbines are limited to water depths of around 200 feet (60 meters).
Floating structures unlock much deeper waters where winds are stronger and more consistent.
The problem is cost: floating wind currently runs two to three times more expensive per kilowatt-hour than fixed-bottom offshore.
That gap has kept deployment small and slow.
Geometry over exotic materials
Zhao’s team did not engineer new materials or complex structures.
They applied basic offshore hydrodynamics principles to derive a simpler, more cost-effective geometry.
The result is a structure built from conventional marine construction materials.
Those materials are cheaper, easier to source, and familiar to the existing marine industry .
The configuration reduces the amount of material required and simplifies manufacturing and installation.
“Using conventional marine construction materials in a cost-conscious configuration allowed us to significantly reduce costs,” Zhao said.
The scale model tested in the study is designed to support a 3.6-megawatt turbine.
The tower stands 285 feet (87 meters) tall.
The blades span 394 feet (120 meters) in diameter.
The design is intended to operate in water depths of 656 feet (200 meters).
A lower center of gravity keeps the tower vertical
The second key innovation is internal stabilization.
Features built into the structure lower its center of gravity.
A lower center of gravity makes the platform more resistant to rolling and pitching from ocean waves.
The practical effect is that the wind tower stays vertical even in strong winds.
Most floating platforms allow some degree of tilt, which reduces how efficiently the turbine captures energy.
A vertical tower keeps the blades facing directly into the wind.
“We also used internal stabilisation features to lower its centre of gravity to make it more stable,” Zhao said.
“These features mean it is possible to keep the wind tower vertical even under strong wind conditions, increasing the efficiency of power generation.”
The design also requires less maintenance and is expected to last longer than existing structures.
Simulations confirmed it can survive a one-in-100-year storm event.
Using deep ocean and extreme weather simulations, Zhao confirmed the prototype can be scaled to support a full-sized tower comparable to land-based turbines.
Governments and marine industries in the UK, Japan , South Korea, and elsewhere have expressed growing interest in floating wind.
It can access offshore regions where fixed-bottom foundations are impractical.
The cost problem has been the main brake on deployment.
At two to three times the price of fixed-bottom wind, floating projects struggle to compete in energy markets.
A 40 percent reduction in capital cost would not close that gap entirely, but it would bring floating wind significantly closer to commercial viability.
Zhao and his colleagues at UQ plan to continue refining the design.
The next step is moving toward larger-scale validation in real ocean conditions.
