Professor Chris Bailey from Greenwich University, who is building computer model, a kind of 3-D virtual jigsaw puzzle, to decide the ordertimbers should be removed and replaced to prevent the ship from collapsing under its own restoration. She is also joined by Dr Sheelagh Campbell from the University of Portsmouth to find out how washing the hull under an electric current will coax damaging salts out of the rapidly corroding metal hull and preserve the shipforfuture generations.
