Please accept this letter as a personal and professional endorsement of the Sperton team for the outstanding business partner to ABB on our large projects, Dolwin Beta & Borwin Alpha.
During a certain period, commissioning offshore to hand over to the client, the Sperton team had some 100 qualified consultants in the project. They always made sure all their assigned representative was supported and due follow up of impeccable performance was always done.
Since my earliest involvement with Sperton, I have found their company to be world-class in many ways. Their representation of ABB to our mutual customer base was very fair, courteous and above all, professional in every respect.
HVDC DolWin2 is a high voltage direct current (HVDC) link to transmit offshore wind power to the power grid of the German mainland. The project differs from most HVDC systems in that one of the two converter stations is built on a platform in the sea. Voltage-Sourced Converters with DC ratings of 900 MW, ±320 kV are used and the total cable length is 135 km.
