About Hydrodyn-OILSOFT

It is an absolute user friendly system, developed specifically for environmental engineers, who may not have much exposure to numerical concepts in data creation , calculation and analysis.

Hydrodyn-OILSOFT is an advanced software package, with a Graphical User Interface(GUI) consisting of pre-processor, multiple solvers and post processor that can simulate fate and movement of oil spills, in rivers, seas and coastal waters of estuarine systems in a complex geometry with high precision using higher order numerical schemes. OILSOFT provides rapid predictions of the movement of spilled oil in all meteorological and hydrological conditions. It includes user friendly graphical interface for entering both wind and hydrological data and specifying the spill source scenario. Hydrodyn-OILSOFT includes many specialized features of graphics and menu driven pre/postprocessor for setting up the input, running the calculation, and selecting and obtaining graphical output from the analysis, animation facilities, trajectory plots etc. It allows fast, flexible creation and modification of computational models to reduce the possibility of errors in the input.

Application Areas

Hydrodyn-OILSOFT covers the following model applications

  • Assessing the risks due to oil spills and impacts on marine life and ecosystem
  • Either as a real-time basis to predict the movement of oil spill or as a scenario model to analyze the possible impact of accidental oil spill.
  • It generates multiple stochastic simulations for selected spill locations using statistical or historical wind time series
  • It can be run to determine most likely spill paths for spills on a monthly, seasonal, or annual basis.
  • Output includes maps showing probabilities of oiling the water surface and shorelines in the vicinity of the spill site, and contours of oil travel time.
  • The software output results can be used to determine the probability of oiling static resources which are stored in the GIS.
  • The software can be used to perform reverse trajectory calculations for selected sites.
  • Calculations can be used to identify probable release locations of spills given current oil locations, or principal avenues of vulnerability for important resources.
  • Outputs of the receptor mode are maps showing probabilities that the spill trajectory passed through a given area, and minimum time contours for spills to reach resources of concern.
  • Predicting the weathering and transport of spilled oil in surface and subsurface.
  • Predicting the probability areas of oil reach and their impact.
  • Risk assessments due to accidental or continuous oil spills and due to operational discharges/leakages.
  • Search and rescue operations.
  • Tidal Circulation and Oil spill transport.
  • Oil spill Trajectory analysis.
  • Analysis of various physical and chemical properties of oil spill in the offshore for EIA studies.
