    • 01. Introduction
    • It was submitted the document titled "Vessel Traffic Conditions in the NOWPAP Area 1996" from Japan at the Second Meeting of NOWPAP Forum on Marine Pollution Preparedness and Response, which was held during April 15-17, 1998, in Taejon, Korea, in the light of necessity to recognize the probability of an oil pollution incident, through a complete understanding of the vessel traffic conditions (vessel course, age, size, etc.) in the NOWPAP area.
      Followings are extracts of the outcome of consecutive investigation on vessel traffic conditions in the NOWPAP area in 1997. That this investigation will be the basic data for further discussion of the need for regional cooperation in the NOWPAP area.


    • 02. Investigation Methods
    • For the analysis, 154,772 cases of ocean voyage of vessels of 500 gross tonnage and above were sampled from the movement data of those belonging to Lloyd's in 1997. The result of the analysis has to be considered through the following points;

    • While collating data, any data thought to be suspicious was not used.
    • Data not substantiated by Lloyd's was not included


    • 03. All Vessels Traffic Conditions
    • Various types of vessels, including fishing vessels, ferries, container carriers, tankers, liquefied gas carriers and general freighters are navigating in the subject area. 8,469 vessels navigated in the subject area in 1997. If the figure can be calculated as one trip that vessel left from a port and entered in a next port, the total number of traffic by 8,469 vessels was 97,667 trips

    • Fig.3
    • shows the number of vessel traffic as divided by ship age. Vessels in service for over 20 years made up 28.6 % of the total number of vessel traffic. One in every four vessels was seen to be an old ship in service for longer than 20 years.

    • Fig.4
    • shows the number of vessel traffic as divided by ship tonnage. Vessel traffic less than 10,000 G/T made up 65.8 % of the total traffic. Traffic of over 100,000 G/T which is called as very large ship was the number of 1,222 trips and made up 1.3 % of the total traffic.

    • shows the number of vessel traffic for 500 G/T and above navigating between nations in the NOWPAP area. The number of traffic on the route between Japan and Korea is considerably large.

Panama making up 26 % of the total vessels. In the NOWPAP countries, Russia held 8 %, China held 9 %, Korea held 4 % and Japan held 3 % respectively, making up a total of 2,030 vessels and 24% of the entire vessels. The average age of all vessels was 13.7 years.

    • 04. Tanker Traffic Conditions
    • A similar method of analysis was utilized for tankers (including chemical tankers, but excluding liquefied gas carriers) which have the potential to be the cause of large scale marine pollution. 1,309 tankers navigated in the subject area, with a total of 13,731 trips during 1997. This makes up 15.5 % of the entire vessels, and 14 % of the entire trips respectively.

    • Table.5
    • shows the super tanker (300,000 DWT and over) traffic navigating between nations in the NOWPAP area Traffic of super tanker of 300,000 DWT and above was 108 trips (23 ships) and these super tankers mostly called at Korean and Chinese ports

    • Table.6
    • shows the ship age of tanker navigating in the NOWPAP area as divided by ship's flag. he countries with over 20 tankers are selected arranging a large number of tanker order.
      In total ship's flag (including flag of convenience) reached 51 countries, Panama making up 28 % of total tankers. In the NOWPAP countries, Russia held 4 %, China held 5 %, Korea held 5 % and Japan held 6 % respectively, making up a total of 256 tankers and 19.6 % of the entire tankers. Average ship age of tanker is 11.2 years, it is 2.5 years younger than all vessels.

    • 05. Summary
    • Although the vessel traffic conditions in the NOWPAP area during 1997 was similar in general to the result of investigation in 1996, it is remarkable that the traffic of very large tanker of 200,000 DWT and over was 689 trips and that the traffic of supper tanker of over 300,000DWT increased especially to 108 trips in comparison with 38 trips of last year investigation. It is considered that the increase of shipping activity in the NOWPAP area is a reflection of high economic development of Far East Asia. However, it also shows the high probability of a possible disaster at sea in this region. We intend to investigate more detailed portion and contribute for safety and environmental protection in the NOWPAP area.
