Moneywise, international seaborne trade accounts for around 60 percent of all world trade. Not only has the value of the global seaborne trade increased in the past years, but the capacity of container ships in seaborne trade was almost ten times higher in 2016 than it was in 1990. In 2016, there were around 1.7 billion tons loaded of international seaborne trade carried by container ships.
It is expected that the higher capacity of container ships will lead to a smaller number of ships in the worldwide fleet. By December 2020, the projected worldwide number of containerships is estimated to be around 5,000.
In terms of ship operators, the container ship industry is dominated by a few: the top five operators command nearly 64 percent of the world liner fleet. Denmark-based shipping conglomerate A.P. Moller-Maersk is the industry leader, owning almost 18 percent of the global liner fleet as of August 2018.
