ABOUT US

PelaStar, LLC was formed in 2013 by parent company Glosten with the mission to design and commercialize a floating wind turbine foundation ideal for utility-scale development in deepwater. Initially conceived as the Tension Leg Turbine Platform (TLTP), the PelaStar tension-leg platform (TLP) technology has been under development by Glosten since 2006.

Glosten engineers designed the PelaStar TLP to perform in deep water, giving developers access to new geographic markets where superior wind resources could only be obtained via deep-water sites. With new technologies, cost is a frequent enemy of adoption, so our engineers refined the design to radically reduce capital and installation costs.

Various platform types were considered, and the TLP emerged as the clear solution based on its potential for low structural weight, low motions, and suitability for the range of water depths being considered by the offshore wind market. In addition, the TLP’s integrated tendon components could be delivered straight from our industrial manufacturing partners to the assembly quay. Today, PelaStar offers a fully-integrated, engineered and certified design package, along with services to complement local requirements and ensure successful project execution.

 

VISION

Our vision is a low-carbon future where offshore wind is a major contributor to a globally affordable, secure, clean energy mix. Deep-water floating wind is a means of opening the vast wind-energy resources found in water depths inaccessible to traditional fixed-bottom foundations.

TIMELINE

PelaStar has played a pioneering role in the floating wind market, including design and patent milestones supported by several major grants that have supplied the bulk of our funding to date. 

2023

PelaStar was among nine teams awarded a Phase 1 FLoating Offshore Wind ReadINess Prize for demonstrating our technology is mature and ready for industrialization. We are now competing for a Phase 2 award.

2022

Sponsored by the UK Department for Business, Energy, and Industrial Strategy, PelaStar partnered with SENSEWind to research and perform design integration of their self-erecting tower and turbine installation systems.

2020

PelaStar and GE Research were awarded a grant, funded by ARPA-E’s ATLANTIS program, to study the benefits of control-co-design, enabling us to integrate the design of GE’s 12MW Haliade X turbine with PelaStar.

2014

PelaStar partnered with Alstom (now GE) and NREL under a grant from the US Department of Energy to develop advanced turbine controls and dampers to reduce structural loads in the TLP’s hull, tendons, and anchors.

2013

Our most important award came from the UK Energy Technologies Institute, which supported 1:50 scale model testing and a complete FEED design and certification review of a PelaStar integrated with GE’s 6MW Haliade 150 turbine.

2011

Awarded a grant from the US Department of Energy to support R&D focused on cost reduction for floating offshore wind. This helped us establish our tendon design concept, our concept design tool, PelaStar Optimizer, and initial installation methods.

2009

Awarded our first grant by the Carbon Trust Offshore Wind Accelerator program, kicking off the design of a PelaStar platform for a 5MW turbine.
