4th International Symposium of Maritime Security Safety & Environmental ProtectionSpatial analysis of oil spills from marine accidents in Greek watersAuthors: Giziakis K., Kanellopoulos N., Gialoutsi S. University of Piraeus Department of Maritime studies 30-05-2013
1. General Overview What is the problem? Marine accidents and incidents ….oil spill….degrading the environment What is the target? Examine the implementation of a framework analysis of shipping based oil pollution by using spatial analysis and geographical information system. Usage thematic maps for the distribution of oil spills Identify hot spot areas in Greek waters
2. Using Geographical Information System in… Maritime accident analysis: Usage of statistical methods to identify areas, where accidents and activities are concentrated Cluster methods……accident prevention …..search and rescue centers allocation Monitoring oil spills Ability to extract oil parameters Map oil spills and define the trends
3. Spatial analysis of oil spills from marine accidents in Greek waters Data 311 accidents from 2001 to 2011 Variables: shipdata Geographical information (latitude, longitude, sea area) Size of pollution Type of accident
8. Spatial distribution analysis of marine accidents and oil spills
11. Conclusions • GIS is an undisputable efficient tool for the analysis of information at marine accidents and on oil spills • Saronikos Gulf: high density of maritime traffic….small spots of polluted areas • Severe marine accident in sea could surpass in size small operational oil spilled accidents • What follows next? Insert factor “vessels movements” …..fomrulate a regression model …..calculate accidental risks
