With the second of the new aircraft carriers coming together like a giant lego set, Boabarge 34 came up the Clyde to collect another section and transport it to Rosyth where it will be fitted into its location on the Prince of Wales.
The barge was towed from Norway by Boa Udin, recognisable to some as ex-Svitzer tug Svitzer Pembroke.
On arrival at Greenock the barge was then handed over to local Svitzer tugs, Anglegarth and Ayton Cross for her journey upriver to Glasgow.
Another piece of the giant jigsaw that will become HMS Queen Elizabeth started the long voyage from BAE Govan to Rosyth where the two new Royal Navy aircraft carriers are being assembled.
Section LB04 is one of the largest modules housing two engines, a hospital, galley and 242 berths.
Local tugs brought the barge down the river, where BB Troll and Carlo Magno were lying waiting to take over for the journey to the River Forth.
