The World’s Biggest Ship

Enormous Engine (1x2)

Air date: Oct 31, 2013

To create the world’s most efficient container ship, the Triple E’s designers have taken the radical step of fitting the ship with not one but two, enormous diesel engines – connected to a pair of giant propellers, each costing one million dollars. We follow the engineers as they build and install this state of the art propulsion system. At the foundry in Germany, where the propellers are being cast, the team use an ingenious chemical process to ensure that no hydrogen bubbles form inside the propellers – bubbles that could cause cracks. While in South Korea, the Triple E’s twin engines, each the size of a small house, are tested for the very first time, prior to installation.
