BE-AWARE II Final Conference, 18-19 November, Ronneby, Sweden Accidents and potential releases of mineral oil the Bonn Agreement Area Co-financed by the EU – Civil Protection Financial Instrument
Background Introduction to the different accident types Frequency of the accident types Spills from the different accident types Future scenario Regional differences Risk Reducing Measures and areas of interest Summary and Conclusions Results of the Quantitative Risk Analysis for Oil Overview
Overall objective: Apply the accident model to describe the: Accident type Location Spill size Spill substance Basis: Traffic model Cargo model Risk Reducing measures Accident statistics Results of the Quantitative Risk Analysis for Oil BackgroundTask H Oil spills
- Ship-ship collision model Node collisions Route collisions - Groundings - STS/bunkering operations/loading buoy/FPSO - Offshore platforms Operational spills Spills from collisions - Wind parks Results of the Quantitative Risk Analysis for Oil BackgroundAccidents covered
Route collisions The collision frequencies depend on: • the length of the route segment • the traffic intensity in each direction • the length, breadth and speed of the ships • the deviation of the ships from the route axis • the causation probability Pc Head-on Overtaking Results of the Quantitative Risk Analysis for Oil Accident typesShip-Ship collisions
Node collisions The collision frequencies depend on: • the traffic intensity in each direction • the length, breadth and speed of the ships • the crossing angle • the causation probability Pc Results of the Quantitative Risk Analysis for Oil Accident typesShip-Ship collisions

Areas with high intensity traffic in narrow lanes gives large contributions when no TSS is applied Largest contributions to reduction of route collisions from TSS Largest contributor to node collisions at Dover Straight Not insignificant contributions from the operational spills from platforms Substantial regional differences in accidents and spills Methodology Summary and conclusion 1
Substantial risk for spills from platforms (Ship-platform collisions, platform accidents, blow-out) Little risk for spills from wind farms (ship-Wind turbine collision) Development of risk on sub-regional level: SB4: More risk for collision, wind farms SB5: More risk for collision Impact of spills have not been evaluated (Be-Aware II) Methodology Summary and conclusion 2
