This is how Wal-Mart gets all its stuff from China.

15,000 containers and a 207' beam! And note the crew size below, for a ship longer than an US aircraft carrier, which has a complement of 5,000 enlisted and officer personnel.

Think it's big enough?

Notice that 207' beam means it was NOT designed for the Panama or Suez Canal. It is strictly transpacific.

Check out the cruise speed of 31 knots, which means the freight arrives 4 days before the typical container ship (18-20 knots) on a China-to-California run. So this behemoth is hugely competitive, carrying perishable goods.

This ship was built in three, perhaps as many as five, sections. The sections were floated together and then welded.

The ship is named Emma Maersk. The command bridge is higher than a 10-story building and has 11 crane rigs that can operate simultaneously.
