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 the new generation of deepwater wind turbine foundations.

Reducing the Cost of Energy
The PelaStar system was 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, and the tension-leg platform emerged as the clear leader due to its potential for a low structural weight, an in-harbor system assembly method, potential to access relatively deeper sites, and superior dynamic responses to sea conditions, which maximizes turbine performance on a floating structure.
TLP is Clear Technology Leader
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.
PelaStar Technology Proven in FEED Study
Recent project work has proven the economic viability of the PelaStar platform system. Glosten developed a Front End Engineering Design (FEED) Study, commissioned by The Energy Technologies Institute, of the PelaStar tension leg platform to support an Alstom 6 MW Haliade 150 turbine. This project has advanced the technology to a point where it is ready for full-scale demonstration.
