Core Elements and Contextual Risks in Marine Oil Spill and Chemical Leak Analysis
Main Points
- Risk quantification through spill volume estimates combined with incident probability and consequence metrics.
- High-risk events often linked to specific ship types, geographical areas, and environmental sensitivity (e.g., Arctic waters, Great Barrier Reef).
- Examples include spill risk assessments for Disko Bay and the Gulf of Finland, highlighting accident types and vessel classes involved.
- Emphasis on integrating traffic data, environmental vulnerability, and accident statistics to prioritize response and prevention.

Scatter Plot Showing Relationship Between Spill Volume and Incident Probability
Context and Interpretation
- This visualization plots oil spill incident probabilities against estimated spill volumes for various vessel accident scenarios.
- It highlights positive correlation trends indicating that as spill volume increases, incident probability also tends to rise.
- Risk prioritization can focus on scenarios with both high probability and large spill volumes to optimize response planning.
- Key insight: risk matrices combining probability and consequences support identification of worst credible spill events.

Context and Interpretation
- The flowchart illustrates the progressive stages from risk identification through risk evaluation to risk control measures for oil spill scenarios.
- Transitions show the logical steps: hazard identification leads to probability and consequence analysis, which then inform risk matrix evaluation and preventive strategies.
- This framework supports systematic prioritization of spill response and resource allocation.
- Effective risk management requires integration of monitoring, incident assessment, and ongoing update of the risk profile.
