All the other types of accidents are less important, since collision and groundings account for 95% of the modeling efforts of all the types of accidents. Moreover, all the other types rely on statistical data only. Accidents at Sea Analysis Collision & Grounding Analysis Collision and Grounding types of accident are linked directly with the AIS data analysis and more specifically, with the position of the vessels and how close they come to each other. All the other types of accidents are less important, since collision and groundings account for 95% of the modeling efforts of all the types of accidents. Moreover, all the other types rely on statistical data only. Accidents at Sea Analysis Collision accidents Types of Collisions: • Crossing • Head on • Overtaking Accidents at Sea Analysis Grounding accidents Types of Grounding • Drift grounding • Powered grounding Accidents at Sea Analysis Collision & Grounding Analysis TWO OPTIONS FOR ESTIMATING THE PROBABILITY OF OCCURRENCE-FREQUENCY (RISK ESTIMATION) Statistical Only Modeling the Physical process Collision & Grounding Analysis Modeling the Physical process Modeling the physical processes consists of two parts: a) Geometrical calculations using input data from AIS (lateral distibution, course over ground, speed, ship length, beam) b) Statistical parameters (causation probability = 1 - The probability of making a succesful evasive manoeuvre given that you are on direct collision corse). Thus, collision and grounding analysis model does have a statistical component, but it is only a small part of the model. Accidents at Sea Analysis Conclusion The main part of the ’Analysis of accidents at sea’ is to figure out the probability (frequency) of a specific accident to occur, that is calculating the risk probability of a specific accident based on the AIS data and statistical parameters. And this is done for both collision and grounding Accidents. PROBABILITY OF OCCURRENCE = RISK ESTIMATION Accidental spill of oil Analysis The main part of the ’Accidental Spill of Oil Analysis is to take into account the amount of risk calculated in the Accident At Sea Analysis (probability of occurrence) and find the closest match against ‘collision model scenarios’ with the aim to ‘forecast/predict’ the amount and type of oil spill at sea. ACCIDENTAL SPILL OF OIL ANALYSIS = RISK EVALUATION OVERALL MODEL – RISK ASSESSMENT ACCIDENTS AT SEA ANALYSIS = RISK ESTIMATION ACCIDENTAL SPILL OF OIL ANALYSIS = RISK EVALUATION DAMAGE IMPACT ASSESSMENT The damage analysis is used to determine the consequence from an accidental spill of oil in a uniform way throughout the project area. The model for environmental damage will be developed with input from the accidental oil spill analysis and the sensitivity analysis. DAMAGE IMPACT ASSESSMENT – HOW?
