New Bolts May Save the Wasa
The Swedish Radio Science Department reports that Stockholm’s number one tourist attraction, the 17th century warship Wasa, is to be saved by carbon fiber bolts.
The Wasa sunk in Stockholm harbor on her maiden voyage on August 10, 1628. More than 300 years later the wreck was found and salvaged and installed in a special museum. But five years ago it was discovered that a sulphur compound was breaking down the preserved hull.
Now researchers believe the source is the rusty iron in the bolts holding the ship together. In the first stage, just three bolts will be replaced with carbon fiber substitutes. If that proves to be the solution, the Wasa Museum says replacing all 5000 bolts will take several years.
