As for Stena Immaculate itself, the owners said yesterday there's seems to be no current pollution being released and no sheen around the vessel, which is encouraging. I've no reason to expect they'd be bullshitting as they're not on the hook for it. It's also no longer on fire at all.
I did hear scuttlebutt that they want to get people aboard today if possible to assess its condition and hopefully get it moved so it can offload and be surveyed properly.
