A section of the ground-level concrete slab in the main engine room of the Skyros Island power station developed significant cracks due to overloading during routine servicing of the power-producing engines. These heavy loads generated excessive bending and torsional stresses on the slab and the underlying beams, leading to severe deterioration of these structural elements.
To address the issue, the engineering team at Theta Ktirion undertook a meticulous design process, considering the station's operational needs and the results of preliminary investigations, including magnetic imaging of reinforcing rods and concrete quality tests. The damaged section of the concrete frame—comprising the slab, beams, and columns—was removed down to the basement level using wet cutting techniques, ensuring uninterrupted operation of the power station throughout the process. A new foundation was constructed, and a heavy-duty reinforced concrete platform, structurally independent from the rest of the building, was erected within the main engine room to accommodate the operational demands.
