The industrial gear manufacturer started the repair work on Lake Vänern, Sweden's largest inland sea and Europe’s third-largest lake, in June.
The 13-week project was planned by ÅF Industry in Karlstad, Lake Vänern, and was only accessible during favourable wind conditions.
Moventas’ service facilities in Finland were used for the refurbishment of components and two drivetrains were replaced with the company’s gearboxes.
Moventas vice-president Antti Turunen said: "Flexibility and fast turnaround of the workshop project allowed us to adjust our operations on-site depending on the weather. On windier days the team was preparing for the next wind gap, and when it appeared, we could react promptly."
