Barges go from brewer to breaking point

I AM researching the fate of the Guinness barges that used to ply the Liffey. My information indicates that three of them went to work in Haulbowline.

One of these has been located near Waterford. It might be the Killiney, but there is reason to believe that it went to Lough Neagh and is still there, half submerged. The other two, apparently, were scrapped. Would any reader know the names of these three craft, and what became of the survivor?

I am conducting this research for the Maritime Institute of Ireland and would be grateful for any information.
