The Busan New harbor will be opened by 2011, after which it is expected that the marine traffic volume around this area would Increase significantly and that very large ships such as 12,000 TEU container ships would come into the port. Therefore, it is necessary to build a new ships' routeing by considering these factors. In this paper, environmental circumstances, marine traffics, and the preceding studies have been reviewed and ships' routeing is proposed through experts' opinions and Delphi technique. For the purpose of validation, the proposed ships' routeings are reviewed by several guidelines on the ships' routeing and through simulation studies.

Yangtze River channel is in natural condition for a long time. There are more to be done in grade of navigation and transport. Since 1980's the rate of vessel in JiangSu channel is going up every year, especially for ocean vessels. Meanwhile, the serious factors such as no sailing at night have become a battlement causing the long period for vessels, high cost for shipowners, lower competitiveness for JiangSu ports along the Yangtze River. It also can not meet the port logistic development. After the Ships' Routeing in JiangSu has been carried out. It has improved the safety of navigation in JiangSu area and reduced the risk of pollution or other damage to the marine environment caused by ships colliding or anchoring in or near JiangSu channel. By analyzing, compareing, calculating and model forecasting. The main focus of the paper is put on the study the development of port, channel in JiangSu and efficiency in many fields. Navigation efficiency of the sailing at night; Safety efficiency of reducing the risk by ships; More efficiency of the higher cargo volumes of the other ports in Yangtze River with the increase cargo volume of JiangSu ports along Yangtze River. The purpose of this study is: To get the social and economical efficiency after the Ships' Routeing in JiangSu has been carried out. Also the role of the Ships' Routeing of JiangSu in the development of Port and Channel.

In this paper, we analysed vessel traffic volume and patterns of traffic flow for ships using areas where included wind farm site and adjacent waters of Daejeong Offshore Wind Farm, and estimated traffic volume by classified navigational routes according to suggestion of rational routeing measures on the basis of classified patterns after installation of offshore wind facilities. Also, we assessed vessel traffic safety for each designed routeing measures on the basis of estimated traffic volume and proposed requisite countermeasures for the safe navigation of ships. With a result of analysing patterns of traffic flow, the current traffic flow was classified by 8 patterns and the annual traffic volume was predicted to 8,975 ships. On the basis of these, expected the vessel traffic volume according to designed four routeing mesaures after installation of wind farm. As result of assessing vessel traffic safety by using powered-vessel collision model of SSPA on the basis of the estimated traffic volume, the value of collision probability was less than safe criteria $10^{-4}$. Thereby we made sure usability of the designed routeing measures for the safe navigation of ships.

The fishery compensation by marine spatial planning such as routeing of ships and offshore wind farms is required objective data on whether fishing vessels are engaged in a target area. There has still been no research that calculated the number of fishing operation days scientifically. This study proposes a novel method for calculating the number of fishing operation days using the fishing trajectory data when investigating fishery compensation in marine spatial planning areas. It was calculated by multiplying the average reporting interval of trajectory data, the number of collected data, the status weighting factor, and the weighting factor for fishery compensation according to the location of each fishing vessel. In particular, the number of fishing operation days for the compensation of driftnet fishery was considered the daily average number of large vessels from the port and the fishery loss hours for avoiding collisions with them. The target area for applying the proposed method is the routeing area of ships of Jeju outer port. The yearly average fishing operation days were calculated from three years of data from 2017 to 2019. As a result of the study, the yearly average fishing operation days for the compensation of each fishing village fraternity varied from 0.0 to 39.0 days. The proposed method can be used for fishery compensation as an objective indicator in various marine spatial planning areas.

Recently, many ships such as fishing boats, cargo ships, high speed ferry boats are visiting Mokpo harbor. In particular, many marine accidents have been occurred at this area due to the narrow channel, a thick fog, the existing of the shallow waters etc. However there is no suitable ships' routeing system which takes account of today's traffic situations in this area. This study aims at the settling of hazardous factors to mitigate the danger to vessels in Mokpo harbor and to secure the safety of maritime environment.

Recently, many ships such as VLCCs, dangerous cargo ships, high speed ferry boats are visiting Yeosu, Gwangyang harbor. The traffic volume of the year 2003 has increased as many as 2.5 times of 1988. However there is no suitable ships' routeing system which takes account of today's traffic situations in this area This study aims at the settling of hazardous factors to mitigate the danger to vessels in Yeosu${\cdot}$Gwangyang bay and to secure the safety of maritime environment.

Since special sea area for traffic safety has been established in 1988, there has been only deep water line for deep draft vessels and no other ships' routeing measure for special sea area on Yeosu Bay. In this work, we suggest several solutions to secure ship's safety and to eliminate dangerous factors which exists in present ship traffic system. Consequently, this work is to propose improved marine traffic system in future.
