Brian Price has sent a third instalment of his collection of QE2 build photos and what a fantastic opportunity we have to view these historic images. Enjoy!
In this picture we can clearly distinguish between the steel hull and aluminium superstructure.
Fastening steel to aluminium was a new technology, call Huck Bolting, which had been tried in Dutch shipyards, and QE2 was the first use of the technique in British shipbuilding.
The two surfaces have to be perfectly clean and then dressed with an epoxy resin before joining and fixing with huck bolts (rivets) and then the area joined is heated to complete the bond.
Notice that the slipway is lined up with a cut in the bank of the far side of the River Clyde, allowing for a little extra ‘wiggle room’ on the launch.
Aluminium was used for the superstructure in order to save weight which could then be translated into extra space inside the ship for passengers and crew....and of course cargo. QE2 was unique in transatlantic liners in that she had the capability of drive-on, drive off cars and vehicles. (During the stevedores strike in NYC I drove 6 brand new Daytona Ferraris off the ship during one call.)
Above is one of the two bow thruster propellers. These were installed in two tubes which cross from one side of the ship to the other at the bow where it is narrowest.
These were used when manoeuvring the ship in harbour, and at times negated the use of tug boats and therefore saved money. The propellers were 6.55 feet (2 meters) in diameter and were driven by 1000 hp electric motors. When the ship was underway, circular doors would then be closed to protect the doors while the ship was at sea.
They were controlled by a joystick on the bridge with repeater controls on the wing of the bridge. Two bow thrusters was quite modest for a ship of this size.
