The OILMAP model comprises several integrated components. The spill
model itself predicts the movement of oil on the water surface and the
distribution of oil in the environment (evaporated, in the water column,
on the shoreline). For these calculations the spill model relies on
environmental data such as wind and currents, physical data such as the
proximity of shorelines, and the chemical data that defines the type of
oil. Each of these types of data can be input and edited using the
appropriate OILMAP component. Spill models

*** OSCAR, DREAM and ParTrack comprise a state-of-the-art 3-dimensional suite of
oil spill and chemical release models
that resolves releases with up to 200 separate chemical components or
component groups, including degradation products. This allows for detailed
and realistic environmental impact and risk analysis. Integrated capabilities include: ·
Laboratory-and
field-calibrated oil weathering based on an international standard
established by SINTEF ·
3-dimensional
dynamic simulation and visualization of surface, subsurface, and coastal
pollutant distributions and concentrations ·
Advanced
gas and oil blowout simulation from deep and shallow waters ·
Stochastic
environmental risk and net environmental benefit analysis (NEBA) ·
Natural
resource damage assessment (NRDA) ·
Detailed
analysis of alternate spill response strategies for oil spill contingency
and response ·
Environmental
Impact Factor (EIF) analysis for oil spills and operational releases such
as produced water, drill muds and cuttings ·
