Scientific divers check the dam at the Saidenbach reservoir
"So far, the results of our investigations have been very promising and there are no dangerous changes to the dam," explains Richard Stanulla from GeoWiD GmbH. The graduate of TU Bergakademie Freiberg and scientific diver trained at the Scientific Diving Center (SDC) has been active in the market since 2012. Together with his team of Judy Adamek, Kevin Schmelzer, Stefan Hildebrandt and Thomas Pohl, all graduates or trainees of the SDC, he carries out structural tests and explorations at dams as well as a large number of scientific studies in standing and flowing waters.
Dam wall test at a depth of up to 40 meters
In Pockau-Lengefeld, GeoWiD is currently working in teams of two with specially developed technology at a depth of up to 2 meters to monitor the construction of the dam of the Saidenbach reservoir, which is a protected monument. It was built between 1929 and 1933 and is the largest raw water reservoir in the Central Ore Mountains dam network. On the waterside, it is plastered and partially tiled. The GeoWiD team has been working with experts from DEKRA since autumn 2020 to document the condition of the seal and to be able to determine any changes and damage. The examinations and measurements directly on-site provide reliable data and enable small repairs that would only be possible selectively or not at all from the surface of the water. About 45 dives have been completed so far. The nitrogen load in the great operating depths and the harsh winter 2020/2021 repeatedly necessitated diving breaks.
Training as a CMAS Scientific Diver
Richard Stanulla’s divers learned the tools of their trade at the SDC of TU Bergakademie. TU Bergakademie Freiberg has been offering scientific diving since 1997 in cooperation with the University Sports Center and the Faculty of Geosciences, Geotechnics and Mining. The Scientific Diving Center has been part of the Faculty of Mechanical, Process and Energy Engineering, Professorship for Technical Thermodynamics since 2018. Training to become a Scientific Diver in Freiberg is possible for all students and academic staff and includes a two-semester course and a two-week final excursion. The participants learn, among other things, how to take samples underwater, how to carry out measurements and how to use measuring devices, tools or cameras.
