Three 1,200-year-old Viking ships that have stood the test of time are embarking on their final and possibly riskiest journey to their new forever home in Norway.
The first to make the move is the Oseberg, which will on Wednesday slowly inch its way from its current location in the old Viking Ship Museum to a newly built addition that will house the national treasures in optimal conditions.
The extremely fragile oak hull, encased in a heavy protective steel rig, will make the hundred-metre journey over 10 hours, lifted by a crane moving on a track on the ceiling.
"There is something deeply moving when you think that these ships -- with their long history and all the voyages they have undertaken -- will embark on their final journey," museum director Aud Tonnessen said.
Named after the places where they were discovered, the Oseberg, Gokstad and Tune -- all believed to have been built between 840 and 910 -- have been housed in a cross-shaped building considered too small and unsuitable to conserve them properly.
"They've been subjected to humidity, vibrations ... Over time, the strain became so intense that they started showing signs that they would eventually collapse onto their supports," Tonnessen said.
A decision was therefore taken to move them to a new climate-controlled facility, built as an extension to the old museum, which should make it possible to maintain the ships in their current condition for at least another century.
The relocation process is perilous.
"We have to complete this operation without causing any further damage to the ships, but we know that each handling is harmful to them," said curator David Hauer, who has been planning the project for years.
"These are clinker hulls (featuring partially overlapping planks) that are 1,200 years old. At the slightest deformation, they split between the rivets, the wood cracks," he explained.
- Endless precautions -
Endless precautions have been taken to prevent any breakage or vibrations during the relocation. The ship will be moved extremely slowly, at a pace of 5.5 minutes per metre.
Among other things, an oil services company experienced in high-precision work -- such as positioning massive structures 300 metres below the sea with millimetre accuracy -- has been called in.
"But this is yet another level," Hauer said.
"The level of precision required, for example when it comes to vibrations, is the same as for electron microscopes in hospitals" which require extreme stability, he said.
"Except here, it involves lifting the electron microscope, moving it, and then setting it back down so you can use it again," he said.
If everything goes as planned, the Gokstad is scheduled to be relocated next during the autumn, and then finally the Tune in the summer of 2026.
All three ships were found in separate burial sites southwest and southeast of Oslo between 1867 and 1904, each one very distinct from the other.
Richly decorated with ornate carvings, Oseberg is considered the best preserved Viking ship in the world.
Gokstad is meanwhile the largest of the three, measuring 23 metres (75 feet) long and five metres wide and with space for 32 rowers.
Tune is much more decomposed than the other two and is believed to have been a particularly fast warship. —AFP
