Competition between global ports is intensifying as the number of calling ports has decreased due to the growth of ship size and the implementation of global environmental regulations has begun. Global ports are pushing for a strategic and concrete transition to smart ports in order to secure port competitiveness in the future. In Korea, however, the government plans and projects for promoting smart ports have yet to materialize, and related papers and research are lacking. In this paper, the concept of smart port was established, and the current status of technology and introduction of smart ports was analyzed. In addition, the concept of Smart Port Index(SPI) was presented in order to objectively and quantitatively compare the level of smartness. As a result,

This paper considers the Marine Traffic Risk Assessment for fixed and moving targets, which threaten officers during a voyage. The Collision Risk Assessment Formula was calculated based on a dynamic ship domain considering the length, speed and maneuvering capability of a vessel. In particular, the Navigation Risk Assessment Model that is used to quantitatively index the effect of a ship's size, speed, etc. has been reviewed and improved using a hybrid combination of a vessel's dynamic area and the Collision Risk Assessment Formula. Accordingly, a new type of Marine Traffic Risk Assessment Model has been suggested giving consideration to the Speed Length Ratio, which was not sufficiently reflected in the existing Risk Assessment Model. The larger the Speed Length Ratio (dimensionless speed), the higher the CJ value. That is, the CJ value is presented well by the Speed Length Ratio. When the Speed Length Ratio is large, states ranging from [Caution], [Warning], [Dangerous] or [Very Dangerous] are presented from a greater distance than when the Speed Length Ratio is small. The results of this study, can be used for route and port development, including dangerous route avoidance, optimum route planning, breakwater width, bridge span, etc. as well as the development of costal navigation safety charts. This research is also applicable for the selection of optimum ship routing and the prevention of collisions for smart ships such as autonomous vessels.
