Gazelle Wind Power has announced a new floating platform design engineered to support wind turbines of 18 MW or greater. The platform, which is currently in the research and testing phase, utilizes modular steel construction for deployment in deep-water environments.
Why it matters
The platform aims to lower capital expenditure and the levelized cost of energy for floating offshore wind projects by reducing structural weight. By utilizing a passive restoring force system, the design seeks to make large-scale wind deployment viable in sites previously considered too costly or challenging.
The platform maintained roll and pitch angles below 5 degrees in simulations of 59.8 m/s wind speeds and 14.2-meter waves. This stability is achieved through three Articulated Mooring Frames and near-vertical mooring lines that provide passive restoring force without active ballast.
The players
Gazelle Wind Power
A developer of floating offshore wind energy technology focused on modular, cost-efficient platform architectures.
The details
The design replaces traditional active ballast systems with a central counterweight and Articulated Mooring Frames — structures that allow for movement while maintaining connection to the seabed. These near-vertical mooring lines create a passive restoring force to stabilize the tripod support structure during extreme weather. The geometry allows for modular steel assembly, which is intended to leverage existing port infrastructure for installation.

The Tech Race
The offshore wind industry is currently seeking designs that can overcome the high material costs associated with semi-submersible floating platforms. This design moves the field toward modular, passive systems to support the next generation of massive 18 MW turbines.
The platform is not yet available for commercial use and remains in the testing phase following a basin-test campaign. Its eventual impact will likely be felt by utility companies, such as the firm currently partnering with Gazelle in Asia, rather than individual end users.
The takeaway
The industry should watch for results from full-scale validation trials to see if the simulated 44% reduction in CAPEX can be realized in field conditions. Success here would confirm the viability of passive mooring systems for the next generation of high-capacity offshore wind turbines.
