HMS Victory: "Potting Compost"...

Post by MikeKozlowski »

...It's looking like Victory was in much rougher shape than was thought and the article states that just about all restoration work done after about 1955 did 'more harm than good':

The world’s most famous warship was in far worse condition than experts believed when they started a $55 million revamp, with her timbers reduced to ‘potting compost’.

On the eve of the anniversary of her finest hour – leading the Fleet to a decisive triumph over the Franco-Spanish fleet at Trafalgar in 1805 – the team heading the restoration of HMS Victory have revealed how urgent the overhaul was.

The ship is undergoing the most comprehensive maintenance project in her recent history, a 15-year project to restore her to how she looked as Nelson’s flagship.

A lot of the ship is currently hidden behind protective tarpaulin, having much of her rigging, masts and sails removed.

The conservation team began work on her hull in May 2022 when scaffolding was erected around the ship to allow her to dry out – Victory is now drier than at any time in her 250-year-plus history – and for work to be carried out in all weathers and for visitors to watch the shipwrights.

Andrew Baines, the project director, said: “Although a cursory look at Victory in early 2022 might have given the impression that the ship was in good condition, in reality a thin skin of paint and filler masked planking that was almost entirely rotten on the ship’s starboard side.

“As soon as the outer, sound, layer was removed, the team of shipwrights were confronted with material that no longer resembled timber and was much closer to potting compost.”

The decayed wood has been removed – but in doing so it’s revealed that the rotting had spread to the frames to a much greater extent than had been assumed, meaning more repair and replacement work.

And while traditional shipbuilding methods fared Victory well for most of her career, more recent restoration work – after 1955 – perhaps caused as much harm as good. Nothing fitted or installed before the mid-50s needs replacing.

“Unfortunately, however, the materials and workmanship of the post-1955 material has helped contribute to the quantity of rot in the hull, and will largely be replaced,” Baines said.

Fortunately, the National Museum of the Royal Navy – which looks after Victory on behalf of the Royal Navy – has carried out considerable research to understand the most appropriate materials to be used and how to minimise the risk of water getting into the timber, rot and insect infestation.

That cutting-edge scientific work comes alongside traditional methods used by shipwrights and riggers, conservators and archaeologists, documenting each stage of the revamp to learn as much as possible about the hull – and to assist future generations maintain and restore Victory when required.

All the degraded planks from the ship’s central section have now been removed, the frames are drying and detailed surveys of Victory as she stands now have been carried out ahead of the next stage of the renovation: replacing those frames and planks.

“Much work remains to be done, but we are on track to complete the project in a little less than ten years, at a cost of [$48-55 million],” Baines said.

Despite the work ongoing on Victory, the traditional Trafalgar Day service and ceremony to honour Nelson and his men will take place on board the ship as normal tomorrow - and the legendary 'England expects...' signal hoisted.

Not uncommon with restoration efforts. They frequently cause more harm than good.

That is rather disconcerting, though Britain was poor in 1955 and she had been bombed.

They've got history on this. They found the Holland 1 sub, restored it, put it on display, and it carried on rusting. So they stripped all the new stuff off and coated the rest with black goop, and put her on display like that. Mary Rose was drenched with fresh water for 3 years, and then sprayed with Polyethylene glycol to replace the water in the cells of the wood, and then allowed to dry out.

How much of this particular issue on the starboard side is at least in part because Victory can't move? Constitution is turned yearly so she weathers evenly, but Victory doesn't have that option, and the starboard side is permanently facing the sea.

I remember HOLLAND I in 1991 as a rusting shell, on her side tucked in the corner in Portsmouth.

Now she’s been reconstructed somewhat to the point where one can clamber around inside her.

Similarly, MARY ROSE is now at least viewable, and many of her artefacts are properly displayed.

It’s great to hear that they’re stripping rot out of VICTORY, although I remember hearing for years that it was putty keeping her together.

I think it's more that the pool of institutional knowledge on how to properly keep a large, wooden hulled vessel nice and repaired had died off by that point.
