When HMS Victory went into drydock in the Portsmouth Historic Dockyard in 1922, she was supported by 22 steel cradles. In the almost 100 years that she has remained on the dock, the historic ship’s 3,500-tonne hull had been to slowly collapse in on itself. To save the ship, the cradles have been replaced by an innovative system of 134 “props” that replicate the loads HMS Victory would have encountered while afloat. The ship will now be, at least figurately, floating in the drydock.
The new props, a collaboration between the National Museum of the Royal Navy and BAE Systems, are more than a series of struts to support the hull. Each prop contains sensors and hydraulics to monitor the load on the ship’s hull and adjust the weight being carried by each strut to most effectively support the 255-year-old wooden structure.
