It received approval from international certification agency UL DEWI-OCC, following a comprehensive evaluation of the turbine.

The Korean company had carried out nearly two years of research & development work since acquiring an operating 5.5MW prototype of the turbine, its designs and the rights to sell the technology from US firm AMSC in 2017.

The prototype has been operating for about five years on Jeju, an island south of the mainland, and reportedly withstood wind speeds of 56.5m/s (203.4km/h) during Typhoon Chaba in 2016.

The 5.56MW model is currently the highest capacity model in Korea’s wind power market, the manufacturer said.

Doosan was last year selected as the contractor for national project to develop an 8MW offshore turbine by the Korea Institute of Energy Technology Evaluation and Planning.

It is currently managing the design, manufacturing and demonstration stages of the turbine, and aims to commercialise the model in 2022.
