GE Renewable Energy has applied to a US court to have two new designs of its Haliade-X offshore wind turbine approved for sale in the country after a judge last month banned the original model from sale there.
The manufacturer is seeking the green light to offer machines with relocated bearings and rotating shafts, which are no longer in the interior of the rotor hub.
The changes are for both the “current” and “next generation” of Haliade-X turbines, the US company said in a filing to the US District Court of Massachusetts yesterday.
Hardware ratings stretch from 12MW to 14.7MW, according to the manufacturer.
GE plans to offer the turbines to customers in the US offshore wind sector, it told the court in the filings.
The application comes after a US District Judge William Young barred GE from selling its Haliade-X turbine in the country in the latest ruling in a patent case involving rival Siemens Gamesa.
The US manufacturer is no longer able to offer a specific design of the 12-14MW machine, which Young had earlier ruled infringed one of the German-Spanish manufacturer’s patents.
However, the US turbine company will still be able to supply the original Haliade-X machines to the 800MW Vineyard Wind and 1.1GW Ocean Wind 1 projects under a specific ‘carve-out’ in the ruling.
