The gearbox was designed and tested in accordance with the DNV-GL's 2010 guidelines for wind turbin certification and the IEC 61400-4 international standard.

Certification means Moventas can move the gearbox to serial production at its site in Finland.

Test results showed that the Exceed provided 20% more torque density with 10% less size and weight than a conventional Moventas 3MW gearbox, the manufacturer said.

Testing of the gearbox started early last year and was completed in September.
