    River sea intermodal transportation refers to the whole process of river and ocean transportation by the same ship without transshipment. The operation of river sea intermodal transportation is mainly divided into two parts, namely river section transportation and sea transportation.
    In China, river sea intermodal transportation is mainly used in the Yangtze River Delta and the Pearl River Delta. It is the main mode of transportation for local foreign trade import and export.
    The river section transportation of river sea intermodal transportation mainly occurs before sea transportation in export intermodal transportation; In import intermodal transport, it mainly occurs after sea transportation. In land sea intermodal transport, whether import or export, the land transport stage can occur before or after sea transport.
    Ships participating in river sea intermodal transport can basically be divided into two categories.
    (1) The ships that initially participated in the river sea intermodal transport were transformed from river ships. These ships were originally large river ships, generally only about 500 gross tons, about 1000 deadweight tons, and the full load draft was less than 4. 5m, belonging to shallow draft B-type ship. Since the shipping capacity along China's coast was not very large in the 1990s, the river sea intermodal transportation of large quantities of iron ore suddenly appeared, which made many shipowners actively build ships and participate in iron ore transportation driven by interests. However, due to design and shipyard technical reasons, the structure and safety equipment of these ships can not meet China's rules for marine ship inspection. Many ships don't even have the hatch cover of the cargo hold, and the equipment of radio communication equipment is almost a blank.
    (2) After entering 2000, shipowners began to build 5000 ton river sea intermodal cargo ships in order to reduce shipping costs and pursue more interests. In the design of such ships, the hydrological conditions of the Yangtze river navigation are fully considered, and the new technology of ship ball nose and double tail is used to solve the problem of ship navigation in the top water of the Yangtze River and improve the maneuverability of ship navigation in the Yangtze River; The propulsion efficiency of the propeller is improved and the ship's speed is improved
