Web GIS-based risk assessment system

Use of the GIS-based Risk Assessment System web tool enables to assess the probability of accidental spill pollution (oil, floating objects, bacteria or any other substance being conveyed) to reach a certain point on the coast or other elements of interest (such as shellfishing areas, beaches, cliffs, areas of high ecological value, etc.) to be assessed along with the vulnerability .

Thanks to the GIS-based Risk Assessment System, it is possible to:

  • Calculate risk based on previously defined ocean-meteorological and discharge scenarios (discharge point, type of substance and amount discharged).
  • Characterise the vulnerability (based on physical, biological and socio-economic aspects).

In this way, action in response to spills is improved, defining coastal protection priorities and helping to identify the best protection and clean-up techniques.

This tool can be used in contingency plans against marine pollution (as set out in RD 1695/2012 of 21st December, approving the National Response System for marine pollution). It is also applicable as a response planning tool or as an operational tool, assessing the risk better adjusted to the ocean-meteorological and environmental conditions at the time of the spill.

The tool can be used in port areas, off-shore platforms, estuaries, coastal or offshore aquaculture. It can also be used in regional areas with maritime traffic (for oil spills or other types of discharges from vessels) or other activities.

The WEBGIS application offers better preparedness and response to oil spills.

Applicable sectors

  • Public administrations and official bodies.
  • People in charge for industrial activities with potential oil spill risks (refineries, shipyards, energy production facilities, fuel suppliers to vessels, etc.). Similar for other types of discharges from other activities.


  • Use of the tool from any device with Internet access.
  • Simplify understanding of the information received by showing data as maps (geovisor).
  • Comply with prevailing legislation that requires potential pollution risk assessment in accordance with the meteorological, oceanographic and environmental conditions, as well as the vulnerability of the area.

This product is being created for Falmouth Port (UK) and partly for Belfast Port (UK).


  • Delivery formats and systems (web application).
  • Implementation: between 2 and 6 months (depending on the baseline information available).


  • Knowledge of the marine environment and the methodology for scenario calculation, simulations, mapping, etc.
  • Specific technologies available:
    • Calculation of the most likely ocean-meteorological scenarios for the area under study: Frequency analysis methods.
    • Generation of spill transportation simulations: TRIMODENA Model.
    • Generation of vulnerability maps: GIS Software.
    • Assembly of the web portal customised for the client: ITSASGIS-5D application + web servers.
