Surface Spill Trajectory Modeling

The spill modeling technicians at The Response Group™ have been trained on approaches to surface spill forecasting using RPS ASA OILMAP software. Spill trajectory modeling software allows for determination of product movement and identification of potential areas of impact. Trajectories can be developed quickly as part of a response or live exercise, or as part of an active preparedness and planning program. Knowing the direction of product movement, and time of arrival, provides the responders information that is critical to planning an effective response.

Air Plume Modeling

Air Plume Modeling determines how air pollutants travel and disperse in the atmosphere as a result of meteorological conditions. The model can predict the downwind concentration of an air plume from any chemical release that may be caused by such things as fires, gas leaks or explosions. This prediction also builds a hazardous zone footprint that can be added to a detailed map using GIS software. Such models are important to emergency responders tasked with protecting and managing areas surrounding the source.

Subsurface Trajectory Modeling

Subsurface, or Deep-water Oil Spill Model and Analysis capabilities will provide rapid predictions of the movement of spilled oil from sub-sea releases both domestically and internationally. Subsurface modeling tracks the fate of oil below and above the surface, allowing us to determine the amount of time it takes for oil to reach the surface and at what location it will reach the surface, and potentially impact a coastline. Using globally forecasted or historical winds and currents from around the world, we can provide results subsurface modelling results from a variety of scenarios ranging from pipeline ruptures to well blowouts.
