Navigation Areas System for vessels was firstly introduced by Vessel’s Safety Ordinance of the Japanese Government-General of Korea in 1935 and the same statute had been applied after independence. Because this Vessel Safety Ordinance was enacted in1961 and was carried on Japanese Statute, Japan set the areas for the Navigation Areas System which includes Korea and has been enforced since 1966.
There are four-area systems for navigation area in the Korea Ship Safety Act and these are: Smooth water area, Coastal water area, Great coasting area, and Ocean going area.
The objective of the Korea Ship Safety Act is to ensure the seaworthiness of vessels which is the aim of marine transportation.
Seaworthiness of vessels is the main factor that sets the establishment of safety parameters of navigation in its broader concept, namely, physical factors of hull, systemic factor for safe navigation and human resources factor, which are the main subjects for safe navigation.
This paper gathered the wind forces and wave heights data of the major sea areas of Korea. The data were compared and analyzed, and were used to evaluate the effects on navigational safety of ships on the Korean Coast with potential risks on sea keeping performance using the weather information provided by the Korea Meteorological Administration.
Modern technology and the ever-changing maritime environment are remarkably developed since 1965. These factors have presently improved the determination of seaworthiness of ships. Together with the fast changing development, it has impacted greatly with present-day maritime realities.
This paper introduces a safer navigation system in the existing navigation area by comparing the domestic and foreign Navigation Acts. It gathered the historical background of other ineffectual systems which were now obsolete and have been replaced. Its aim is to construct a solid foundation for reliable navigation area system and sound information for a safer navigation and cleaner oceans.
