(1) Strong passing ability. Ocean transportation can utilize natural waterways that are accessible in all directions, unlike trains and cars that are limited by tracks and roads.
(2) Large transportation volume. The carrying capacity of ocean transport ships is far greater than that of railway and road transport vehicles. The carrying capacity of a 10000 ton ship is generally equivalent to the carrying capacity of 250-300 carriages.
(3) Low shipping cost. The sea freight volume is large, the voyage is long, and the transportation cost allocated to each freight ton is relatively small.
