Thats the way I read it too. I thought that plans were already underway to survey the UK’s seabed wrecks?

Yes – but it is with the aim of locating them.

Seems a bit odd to me to be spending a lot of money twice.

It would not be duplication – the Sunderland survey is to investigate the condition of this particular wreck with a view to recovering it. They already know where it is.
