World's Biggest Shipbuilders - Episode Guide

In the South Korean shipyards of Okpo and Sungdong, two teams are building a giant tanker– the Maersk Tangier, along with the world's biggest jack-up rig – the XLE4.

The workers face one of the heaviest lifts any of them have ever attempted - hoisting a giant 3000 tonne leg well into position, with the help of the yard's floating crane.

The Tangier is welded together from a hundred and twenty nine giant steel blocks. As the challenges increase for the tanker team, the rig team is also feeling the pressure.

The construction of the vessel's bow and stern begins at two shipyards in Poland, but it's a bumpy start for the new build. Meanwhile in Korea, the XLE4's hull is being completed.

In Norway, workers prepare for the delivery of the super tug's hull pieces. Back in South Korea, the Tangier is about to take to the open sea for the very first time.

Finally complete, the Tangier has left port to begin her maiden voyage. On the other side of the world, the super tug team race against the clock to finish the build.
