The largest piece of a structure set to become the world's biggest turret has set sail from Dubai.
The turret is currently in six pieces, but when fully-assembled will stand almost 100m (328ft) tall - as high as the Statue of Liberty - and weigh 10,500 tonnes.
It will eventually be used to anchor Shell's Prelude, a 600,000 tonne floating facility to liquefy natural gas off Australia's coast.
It took over six hours to move the turret piece onto a barge for its three-week journey to South Korea, where Prelude is being assembled.
