Presentation
A Suite of Risk and Risk Mitigation Tools
DescriptionThe Norwegian Coastal Administration (NCA) has over some years developed a suite of computer tools to assess and mitigate risk resulting from ship accidents. The suite consists of:
AISyRISK – focusing on the frequency of accidents and near misses and the risk of oil spills and loss of lives from ship accidents.
EnviRisk – focusing on environmental vulnerability, environmental consequences, and environmental risk from ship accidents.
RespRisk – focusing on timely response, the available resources, and the gap between wanted response time and capacity and existing response time and capacity.
The computer tools are very data driven – BIG DATA.
AISyRISK uses high resolution AIS data, ship databases, wind, weather, sea currents, bathymetry, previous accident statistics, and expert judgements to calculate accident frequencies and risk.
EnviRisk uses the data from AISyRISK as starting points for oil drift modelling. More than 7 000 000 separate oil drift simulations are run every month. The simulations are run with weather and sea current data from the actual time and place they represent. Vulnerability for around 100 sea bird, marine mammal species, and species in the water column are used to calculate environmental consequences and environmental risk.
RespRisk uses the distribution of spill risk and environmental risk combined with the oil spill recovery (OSR) resources and efficiency of the OSR resources in the given weather conditions to calculate a gap between wanted and existing OSR response.
All these tools use infographics to visualize data in maps and graphs. For AISyRISK the finest resolution for AIS data is used. That means every 2-6 seconds for the most frequent reports from the ships. Results from AISyRISK are aggregated to 1 x 1 km and 10 x 10 km. For EnviRisk and RespRisk a 10 x 10 km resolution is used for the results. Results can be aggregated or filtered for any area using the geometry (coordinates) of the area. Typically, we use management plan areas (large sea areas), counties and municipalities. The time resolution for the results is one month.
The tools have been developed with open source as a prerequisite and documentation and methodology is available for download. It is possible for another country or business to reproduce the tools based on the source code and documentation. Several customizations might be necessary and, depending on scope, substantial processing power and data storage capacity are needed.
