Some ships can carry over 14,500 twenty-foot equivalent units (TEU), such as the Emma Mærsk, 396 m (1,299 ft) long, launched in August 2006. It has been predicted that, at some point, container ships will be constrained in size only by the depth of the Straits of Malacca, one of the world's busiest shipping lanes, linking the Indian Ocean to the Pacific Ocean. This so-called Malaccamax size constrains a ship to dimensions of 470 m (1,542 ft) in length and 60 m (197 ft) wide.[31]
