Description

  The present invention relates to a ship for cargo transportation suitable for transporting cargo as it is or in a state of being accommodated in a container.

  Currently, freight is mainly transported by truck over land. The land transportation by truck has the advantage that the transportable area is wide and the mobility is high. However, due to the growing awareness of environmental issues in recent years, especially the growing awareness of reducing carbon dioxide gas emissions, bulk transportation is possible, and as an energy-efficient way of transporting cargo, marine transportation by container carriers and other cargo carriers. Is attracting attention.

  As a container ship, a container ship in which a cargo hold is provided in a hull and a container is loaded on the cargo hold and the deck upper surface is widely used. Although the container ship having this hold has a high container loading capacity, it has a problem that it is difficult to berth at a shallow port facility because the full waterline is deep.

As a container ship with a shallow full waterline, Patent Document 1 discloses a container ship in which the depth of the ship body is reduced by loading containers only on the deck upper surface without providing a hold in the hull. Yes. In this patent document 1, in a ship illustrated as an example of a container ship having no cargo hold, a watertight trunk for improving restoration performance and a watertight trunk on the upper surfaces of the left and right decks of the ship. And a closed passage.
