5 Oil Spill Trajectory Modeling Copyright Oil Spill Response Limited.

6 What is Oil Spill Modelling Industry utilises computer modelling to estimate the likely fate and trajectory of oil pollution to support the determination of a level of consequence Support decision making during preparedness and response SMV is identified as a Capability Copyright Oil Spill Response Limited. 6

7 Stochastic and Deterministic Source of Figures: JIP12 GPG Contingency Planning for Oil Spills on Water Stochastic Modeling provides a statistic summary of all single trajectories run for a given scenario Copyright Oil Spill Response Limited. 7

8 Fast Growing, Technology Driven Tool Once upon a time, we all use 2D oil spill modeling, instead of modeling. What else modeling could potentially do to assist the responders? Copyright Oil Spill Response Limited. 8

9 Modelling +Sensitivity &Infrastructure Identify the resources at risk and the severity of impact Environmental Social/Economical Infrastructure and access Airport, port, roads, stockpile Contribute to the establishment of COP Mapping Copyright Oil Spill Response Limited. 9

10 Effect of Response Techniques What happens if we apply subsea, aerial or vessel dispersant?? Based on realistic assumption of timing to cascade relevant resources to scene, as well as operational windows. Support NEBA Copyright Oil Spill Response Limited. 10

13 Visualisation in Oil Spill Response Copyright Oil Spill Response Limited.

14 What is Visualization? Data can be powerful if you understand what it is telling you! Copyright Oil Spill Response Limited. 14

15 General Definition of Visualization Visualization in the generic sense can be defined as any technique for creating images, diagrams or animations to communicate a message Source: New York Times / Olympic medal Dominance Present lots of data in one place Bring out trends, patterns and correlation that may go unnoticed in text data Make complex data more accessible, understandable and usable Copyright Oil Spill Response Limited. 15

17 What is COP? A Common Operating Picture (COP) is a computing platform based on Geographical Information System(GIS) technology that provides a single source of data and information for situational awareness, coordination, communication and data archival to support emergency management and response personnel and other stakeholders in or affected by an incident.

18 Common Operating Picture Data Sources Situation Unit Post Macondo Dashboard Components Command Centre Developing COP specific to their needs Source: The Omega Group Copyright Oil Spill Response Limited. 18

19 COP Challenges Managing Data Data Standards Unprocessed Information Dump Unfocused Awareness Decision Framing left to Command Team? Shared Understanding Integrated perspectives Actionable Knowledge Tailored Decision Framework Perspective Metadata Copyright Oil Spill Response Limited. 19

20 OSRL s Visualization Role We provide basic visualisation or feed into a COP... Data we can provide and visualise Modelling Aerial surveillance Satellite imagery Dispersant tracks Shoreline types & sensitivities Provide correct and complete metadata! Copyright Oil Spill Response Limited. 20

21 Integration of various reports on a common platform An Example Location: Fakeville, 60 nautical miles offshore Scenario: Collision between A Random Tanker and Another Random Tanker Oil Spilled: 200T of Some very bad Crude oil Source: Google Images Response Planning Type of oil spilled? The direction of slick? Weathering behaviour? Resources at risk? Resources available? Integration of various data sources for better response decision making Aerial Surveillance, Oil Spill Modeling Results, Satellite Imagery Copyright Oil Spill Response Limited. 21

24 The need for Integration Modelling results are to be used for guidance purposes only. Copyright Oil Spill Response Limited. 24

25 OSRL s Visualization Challenges New technology UAVs, aerostats = more data to visualise Ensuring we can integrate into all our Member s systems Maintaining an oversight of our Member s COP developments Ensure we are compatible with industry best practice and standards Copyright Oil Spill Response Limited. 25
