  • PelaStar Tension Leg Platform for Floating Offshore Wind

    The PelaStar tension leg platform (TLP) provides a scalable, integrated blade tip–to–seabed solution that minimizes the cost of energy in deepwater offshore wind sites. It represents a new generation of deepwater wind turbine foundations.

    Reducing the Cost of Energy

    The PelaStar system was first conceived by Glosten engineers in 2006, who saw a need to reduce the capital costs of offshore wind and access sites with superior wind resources. Various platform types were considered, but the tension-leg platform emerged as a clear leader due to its potential for a low structural weight, access to deep water sites, and superior dynamic responses to sea conditions, which maximize floating turbine performance.

    Proven Technology

    PelaStar combines proven technology with rigorous research, development, and engineering. By adapting established TLP technology from the oil and gas industry and incorporating breakthroughs in critical structural, mooring, and anchoring elements, PelaStar has addressed the complex challenges of offshore wind power development.
    Fundamental work was completed in a Front End Engineering Design (FEED) Study of the PelaStar tension leg platform to support an Alstom 6MW Haliade 150 turbine. Commissioned by The Energy Technologies Institute, this project advanced the technology to readiness for full-scale demonstration.

    Evolving, Disruptive Design

    The PelaStar concept continues to be developed through ongoing engineering contracts. New variants for larger turbines show that the foundation system scales well and provides the same optimized performance for larger floating offshore wind turbines.

    How can we help you?

    PelaStar offers a smart combination of features that sets its commercial scale Cost of Energy below competing floating technologies while minimizing turbine motions and maximizing availability over the installed life.
