How were cooling towers built?
They are often constructed as hyperboloid, doubly-curved concrete shell structures supported on a series of concrete struts. The foundations typically consist of an inclined pond wall forming a circular ‘tee’ beam with a wide concrete strip. The beam acts to resist the lateral load of the tower’s shell structure.
When did Ferrybridge cooling towers collapse?
1 November 1965
On 1 November 1965, three of the cooling towers collapsed due to vibrations from Kármán turbulence in 85 mph (137 km/h) winds. Although the structures had been built to withstand higher wind speeds, the design only considered average wind speeds over one minute and neglected shorter gusts.

How thick are cooling towers?
It is the shape that gives it its strength.” For the majority of their height, a typical cooling tower is between just 178 and 180 mm – or 7 inches – thick. It’s a testament to the original design and construction that they require such limited maintenance more than half a century after plans were first drawn up.
What causes a cooling tower to overflow?
The reason for the overflow condition is that the condenser water pumps are oversized for the cooling towers they serve. During normal operation, the recommendation is to not flow at full capacity or to bring additional cooling towers on line if full condenser water capacity is required.
