STX Shipbuilding says it has developed the world’s largest container ship, which is capable of carrying 22,000 twenty-foot equivalent units (TEU) — four times the size of the largest container ship, the Emma Maersk, which is capable of carrying 13,500 TEU, the Wall Street Journal reports. The new diesel-powered ship would save up to 40 percent in fuel cost per transported TEU, but would be too big for most ports and could likely only travel between Shangai and Long Beach, California.Measuring 1,500 feet long, 200 feet wide and 100 feet deep, STX’s giant vessel could leave Samsung Heavy Industries in its wake. SHI announced late last year that it had developed a 16,000 TEU ship.
The Panama Canal seems to be expecting ships to be built bigger. Once complete in 2014, its new navigation channels will be 51 feet deeper and at least 715 feet wider. The locks themselves will be 400 feet longer and 70 feet wider than the existing locks, WorldTrade Magazine reports.
