THE GEOGRAPHY OF TRANSPORT SYSTEMS

The first round-the-world routes were introduced in 1984 by the Taiwanese maritime shipping company Evergreen. This route took about 69 days and was serviced by about 10 4,000 TEUs ships in each direction (Westbound and Eastbound). Each port was thus called twice a week. However, by early 2002 this service was replaced by two pendulum services (North Europe, North and Central America and East Asia; North Europe, Asia and the Pacific North West) offering higher service frequencies.
In 2005, a new round-the-world service was introduced by China Shipping Line (AMAX) that includes a rotation of ten 4,250 TEU containerships (the maximum size that can go through the Panama Canal) completed in about 62 days. This service was mainly designed to support Chinese exports to Europe and the East Coast of North America and bring back empty containers on the leg back across the Pacific through Los Angeles.
