What could possibly go wrong?
Manitoba Hydro has shut down a dam after a European engineer alerted Hydro’s staff to possible cracks in the plant’s underwater turbines. […]
Early last month, a European engineer who worked at Iron Gate and knew Jenpeg was the only dam in North America with similar, Soviet-made turbines, sought out Hydro’s engineers at a conference overseas. So serious was the European engineer’s warning, Hydro shut Jenpeg down almost immediately about two weeks ago. Last week, Hydro’s engineers inspected the first turbine and found many cracks, about half a centimetre deep, on the shaft near the propellers — a part of the turbine that’s hard to get at and not normally inspected. Engineers are usually more concerned with the end of the shaft that’s closer to the power-making equipment, said Schneider.
