January 2018 was a record month for new vessel deliveries, with shipping lines seemingly intent on continuing to order new, bigger ships. As a result, the active total fleet deployed has increased by some 10.8% in the last year, and to date it is now just under 21 million TEU. New, larger tonnage is expected to be introduced on the main arterial trade lanes of Asia-Europe and Asia-North America, with existing tonnage cascading onto secondary trade lanes. This will increase the average size of vessels deployed across all the main trade routes.
