Risk Analysis Methods (Consequences)

The hazard diamond is used to identify and analyze the different risks associated with hazard sources. The hazard diamond or the so-called fire diamond is defined in the NFPA (704) which is the Standard System for the Identification of the Hazards of Materials for Emergency Response. The four divisions of the diamond are color-coded to represent flammability (red), health hazard (blue), chemical reactivity (yellow) and special hazards (white).The Hazard diamond is normally used to identify the risk associated with hazardous materials and dangerous goods.

The preliminary hazard analysis (PHA) is a semi-quantitative risk analysis methods that is used to identify potential hazards and the corresponding top events (risks). The PHA sheet identifies as well the required measures and follow-up actions to control the hazard sources. The PHA should consider hazardous components, facilities, safety-related equipment, and environmental constraints.

Originally, the scenario technique came from the military field, but today it is also frequently used for economic and social issues. Basically, the scenario technique combines quantitative and qualitative forecasting elements. Thus, no pure linear projection is made on the basis of historical data. The aim of the procedure is to prepare companies for future developments in order to improve their ability to act. The complexity is reduced by the calculation and exclusion of inconsistent future developments. The scenario technique provides consistent future projections based on the information collected during the process.

The Seatrack Web system consists of three main parts: forcing in the form of forecasted flow and wind felds, an oil drift model and a graphical user interface. The oil drift model PADM has been jointly developed by the Swedish Meteorological and Hydrological Institute (SMHI) and the Danish Maritime Safety Administration (DAMSA). It is executed whenever a Seatrack Web user requests a simulation. The graphical user interface has been developed at SMHI and is based on open source GIS-server technology, i.e. the user interacts with georeferenced data in a map. The SeaTrack Web tool can be used to analyze the consequences of oil spill drift to a particular sea area, Where does the oil spill drift to in the sea area. The method is selected based on the cooperation with the OpenRisk Project.
