Kremsmüller at Work High Up in the Alps

In the heart of the Vorarlberg Alps, the Obervermunt II underground hydroelectric power station is undergoing extensive construction work.

For GE Renewable Energy, two new generators with a diameter of approximately eight meters are to be assembled in the heart of the mountain. Six special transports, each with a load of 120 tons, were necessary to haul the components with their imposing size and weight to the site. The convoy of two trucks and a low-loader measured up to 66 meters. After reloading onto a self-propelled modular transporter (SPMT), the parts were conveyed over the Silvretta High Alpine Road to the power station cavern at 1,600 metres.

The fitters were, and are, in the camp at around 2,000 metres for 10 days at a time during the construction phase. The contract has been running since April 2017 and is expected to be concluded in April after a one-year construction period, depending on the weather and the risk of avalanches in the region. In addition to assembling the generators, Kremsmüller is a reliable partner for this project through its mechanical production in Krieglach. Parts needed at short notice are conveyed with the next fitters directly to the job site in order to avoid delays. By way of example, special spacer plates or aluminium parts are manufactured, which are characterised by high-precision and custom-fit machining.

Paul Hunger, Site Leadership Manager PMSI at GE Renewable Energy comments, “As with several projects in the past, we have also contracted Kremsmüller to provide assembly personnel for the OVW II project. The qualifications of the crews and the execution of the installation once again meet our stringent quality demands. For construction sites with such special requirements, fast reaction times and flexibility in all areas are indispensable”.
