Challenging sites in challenging times. Amid the ongoing Covid-19 crisis we started maintenance and repair works on wind turbines in Southern Argentina. The works will continue throughout a period of number of months before the customer will take over. Our colleagues have performed similar tasks already virtually around the globe on- and offshore. "With the works we started recently in Argentina we underline the international capabilities BWTS GmbH has achieved in the last few years. We are very grateful to our customers for entrusting us once again with such tasks" said Marc Wollschläger, Head of Business Development BWTS GmbH.

"We are excited about this challenge and are looking forward to continuing to support our customers in their international endeavors"
