Task
Dismantling, cleaning, repairing, modernisation, reassembly and installation of heavily silted generators from Donau Chemie AG's Landeck hydroelectric plant.

Background
A cyclone originating in the Canary Islands struck North Tyrol on the 22nd and 23rd of August 2005 creating severe flooding of the river Trisanna in the Paznaun valley and the river Rosanna in the Arlberg area. The previous highest recorded water mark was exceeded twofold and in parts even threefold. This in turn created havoc at Donau Chemie AG's hydroelectric plant in Landeck, endangering the very existence of the plant itself. Within a few hours Trisanna's and Rosanna’s respective water levels increased so dramatically that the hydroelectric plant was completely flooded – for the first time since the building of the plant in 1903. The generators and other machines were buried by a three metre-thick layer of debris and silt which completely filled the halls. For three weeks heavy machinery was employed to free the hydroelectric plant from its mud cover and unearth the buried generators. At the end of October 2005 Baumüller Reparaturwerk was able to dismantle the generators, transport them to Nuremberg, and begin the repairs.
