Description
The huge volume of hydrocarbons transported through pipelines and by ships poses a continuous risk to the environment due to accidental spills. Understanding the processes determining oil trajectory and fate, and learning oil spill simulation tools, allows environmental professionals to design better response plans, and help mitigate future events.
This course provides insight into the main processes that govern overland and water oil spills and offers practical training to perform oil spill simulations using the OilFlow2D computational model. The course offers hands-on experience in setting up and running a variety of scenarios including pipeline spills hitting sensitive areas, and spills on sea and riverine environments, allowing to determine where the oil will go, giving the spill location and volume.
Learning topics include:
- Type of hydrocarbons and their characteristics.
- Crude oil properties databases.
- Behaviour of hydrocarbons in the environment.
- Concepts and theories of the process of oil spreading on the surface of the water and land.
- Influence of the wind, currents and waves in the spreading processes.
- Formulation to calculate Evaporation, infiltration, emulsification, dissolution, interaction with shore, heat transfer, etc.
- Effect of oil fate processes on oil viscosity and density.
- Modelling as a tool to support oil spill preparedness and response activities.
- OilFlow2d spill simulation model.
- How to better use an oil spill model to evaluate overland and water spills.
- How to apply oil spill models for planning and decision-making.
- How to setup spill scenarios to assess spill response.
- How use OilFlow2D and Geographical Information Systems (GIS) to assess overland spills using Contingency Plans, and Environmental Risk Assessments.
The course will cover the following topics:
- Evaporation, emulsification, dispersion and sinking.
- Change of physical properties such as viscosity and density.
- Influence of the wind, currents and waves in the spreading processes.
- Advantages and limitations of modelling.
- Methods to mitigate the effect of oil spills.
- Dispersants.
- Application of simulation models for the design of contingency plans.
- Creating oil spill trajectory animations.
- Use GIS tools to create oil spill location maps.
The course includes:
- OilFlow2D computer model license valid for 3 months.
- Course Presentations.
- Videos.
- Tutorials.
- Comprehensive model documentation.
After completing this course participants will be able to understand the main processes determining the fate and trajectory of oil spills and to apply the OilFlow2D model to assess overland spills and oil spills in rivers and coastal areas.

Course Presenter
Reinaldo Garcia is an former Wessex Institute of Technology Research Fellow who stayed at Ashurst from 1997 to 1998. He obtained is MSc in Hydraulic Engineering from the Ecole Polytechnique Montreal, Canada and his PhD from the University of Central Venezuela. He is a consultant for the World Bank and the Interamerican Development Bank. Dr Garcia is the creator and leader of the development team of the OilFlow2D and RiverFlow2D, flexible mesh models. He has more than 38 years of experience developing and applying models to simulate oil spills, river flow, and hazard assessments. Dr Garcia has worked in hundreds of modelling projects in the USA, and in more than other 20 countries in Europe, Asia, and South America, and is considered an international expert in the field.
Dr Garcia has taught more than 50 international courses on environmental modelling worldwide. He lectured at the University of Miami, Florida from 2004 to 2006. In 2006 he was appointed Senior Research Scientist at the Applied Research Centre of Florida International University (FIU). Presently Dr Garcia shares his research activities at the Florida International University Institute of Environment with his model development and consulting at Hydronia USA and Hydronia Europe, private firms that commercialize OilFlow2D and other computer models.
