Research on Regional Disaster Prevention Measures to Assume Oil Spill Accident from Sakhalin Oilfield

本研究的结果如下：为了减少二维海流信息中的不确定性，在系统中实现了观测信息的同化，以进行溢油分析和预测。RADAESAT等卫星数据可以提取海流信息，但考虑到溢油事故中的物理现象，时间频率较低。我们采用RADARSAT数据作为浮油模型的同化数据。然而，当应用于海面流提取时，由于雷达卫星的低时频，模拟不适用。本研究利用陆基航海雷达提取海流作为溢油模拟系统的同化数据。利用鄂和须海的实测数据对结果进行了校正。该系统将扩展到萨卡林岛的溢油模拟。由于雷达资料与观测资料的比较，没有得到足够精度的验证。2) ESI地图作为溢油事故利益相关者冲突调节工具的应用。通过在以海滩结构等自然信息为主的ESI地图中加入渔业信息等社会信息，实验制作了溢油事故利益相关者利益调节工具。3)对溢油事故区域应急预案的探讨利用s的结果输出，从Anthodia溢油事件的经验教训出发，对区域溢油事故应急预案进行了探讨，以安排利益相关者之间的冲突现状。本研究提出利用ESI地图作为解决方案，并在北海道滨岛海岸正面验证了ESI地图。

The result of this study is as follows.1)Extension of oil spill simulation systemTo reduce uncertainties in 2-dimensional sea current information, the assimilation of observation information is realized as part of the system for oil spills analysis and prediction. Satellite data, such as RADAESAT, can extract the sea current information, but considering the physical phenomena in the oil spill accident the time frequency is low. We have used the oil slick by using RADARSAT data as the assimilation data in oil drift model. However, when applying for extracting the sea surface current, because of the low time frequency of RADARSAT, the simulation is inapplicable.In this study, the land base nautical radar is used to extract the sea current as the assimilation data of oil spill simulation system. The result is calibrated by using in sitsu data in Sea of Okhotsuku. This system will be extended for the oil spill simulation from Sakalin. As a result of the comparison between radar data and observation data, there was no verification at the sufficient accuracy.2)Application of the ESI map as a tool which adjusts the conflict between stakeholders in oil-spillBy adding social information such as the fishery information etc. to the ESI map mainly on natural information such as the beach structure etc., the tool which could adjust the interest between stakeholders in the oil accident was made experimentally.3)Discuss on the regional contingency plan for oil-spill accidentUsing the output from 2s result, the regional contingency plan for oil-spill accident the was discussed for arrangement of the present condition of the conflict among the stakeholders from lessons of Anthodia oil spill's incident. This study proposed using an ESI map as a solution, and verified the ESI map positively in the coast of Abashiri, Hokkaido pref..
