I was wondering if there are any barge carriers left in commercial service, but at least the category here in ShipSpotting.com seems to have some recent photographs of e.g. Eide Trader in Europe and some smaller Chinese barge carriers.
Still, a disappearing breed. US Military Sealift Command also maintains two or three SEABEE carriers in reserve status. Of the four SEABEE ships built in Vuosaari shipyard (Helsinki, Finland), two bigger ones (including Yulius Fuchik from the book "Red Storm Rising" by Tom Clancy) were scrapped a decade ago and two smaller ones have been converted into a pipelaying vessel and a floating power plant. The nuclear-powered LASH carrier Sevmorput is also facing decommissioning and demolition.
