Plant operators and planning engineers opted for maximum reliability when it came to the repair and refurbishment of the huge Sayano-Shushenskaya dam in Russia, as well as the coating of the
cooling towers of the Bełchatów power station in Poland (two photos left). MC know-how also helped in the re-lining of the headrace tunnels that duct the high-pressure water into the Amsteg
