PelaStar, Glosten’s tension-leg platform (TLP) technology, has been named a winner of Phase Two of the US Department of Energy (DOE) FLoating Offshore Wind ReadINess (FLOWIN) Prize. Our TLP is one of just five winning technologies the DOE has recognized as viable for industrialized manufacturing and deployment of gigawatt-scale offshore wind farms in the United States.

The FLOWIN competition was designed to encourage the rapid development of floating offshore wind supply chain solutions that can help the US meet its decarbonization goals. Phase One required participating teams to demonstrate their technologies were mature enough to warrant industrialization and that they had viable plans to develop a path to serial production and deployment. Nine Phase One winners were announced in March of 2023 and each team proceeded to Phase Two to adapt their designs for serial production, detail plans for mass production, assembly, and deployment, and prepare a cost estimate and production throughput analysis for deployment of a utility-scale floating wind farm.

PelaStar partnered with Everett Floating Structures, FibreMax, Avient-Dyneema, GMC Limited, Triton Anchor, Havfram, Foss Offshore Wind, Geodis, TRC, and Pacific Northwest National Laboratory to develop an aggressive deployment plan: one 15MW floating wind turbine assembled and installed every week starting in the early 2030s. In addition to working out the logistics, the team supplied an estimate detailing the cost of such an effort.

The judges awarded a $450,000 cash prize and technical services vouchers for US National Labs to the five teams with the most feasible industrialization strategies. PelaStar was the only deepwater tension-leg platform in the running, and as a Phase Two winner, will advance to the next round of the competition. In Phase Three of FLOWIN, PelaStar will advance location-specific supply chain plans to compete for the final $900,000 cash prize.
