Vattenfall has started a tendering process that will award a EUR 3 million contract for blade repair services on three offshore wind farms that the company operates in Denmark and Germany.
According to an early information notice issued on 8 January, interested parties can submit a request to participate until 2 February, with all contract details to be provided in the ITT & PQQ phases.

The offshore wind farm was built by Elsam (later DONG, now Ørsted). Vattenfall acquired a 60 per cent stake in Horns Rev 1 in 2005 and today owns the wind farm together with Ørsted (40 per cent), with Vattenfall being the operator.
Located west of the island of Sylt, DanTysk and Sandbank offshore wind farms each have a generation capacity of 288 MW.
DanTysk comprises 80 Siemens Gamesa 3.6 MW turbines that have been in operation since 2014. Sandbank offshore wind farm, which has been in operation since 2016, has 72 Siemens Gamesa 4 MW turbines.
