container ships

In the late 1950s container ships set the pattern for technological change in cargo handling and linked the trucking industry to deep-Sea shipping. These highly specialized ships carry large truck bodies and can discharge and load in one day, in contrast to the ten days required by conventional ships of the same size. The rapid development of the container ship began in 1956, when Sea-Land Service commenced operations between New York City and Houston, Texas. Barge-aboard, or lighter-aboard, ships, also called seabees (sea barges) or LASH (lighter-aboard ships), resulted from an evolutionary development of the container ship. They are capable of carrying about 38 barges, or up to 1,600 containers, or a combination of containers and barges. Their design enables them to deliver cargo to developed or undeveloped ports, without the need for berthing.
