Siemens Gamesa has announced a shake-up of senior management posts – among them the appointment of Andreas Nauen as the new head of its offshore wind business – as the newly-created OEM giant continued its turbulent first year of existence.

Nauen – until 2015 the chief executive of turbine OEM Senvion – replaces Michael Hannibal as Offshore CEO for Siemens Gamesa from 1 November.
