Spill Impact Analyst

Spill Impact Analyst provides the pipeline industry with in-house capabilities for overland spread and water transport analysis for hazardous liquid pipelines.

This flexible ArcGIS extension uses the most advanced overland flow analysis engine, FLO-2D, to identify could-affect and not-affect segments for pipeline integrity management. The tool simplifies the tasks required to perform the analysis on an ad-hoc or regular basis.

FLO-2D performs overland spread analytical functions within Spill Impact Analyst. It was specifically selected because of its advanced modeling capabilities and is superior to older raindrop or buffered-vector approaches. FLO-2D models the actual physical process of a wave front propagating over terrain. The resulting spill plumes consist of individual DEM grid cells with impact time, final volume, etc. for detailed analysis.

FLO-2D and New Century Software have an exclusive license arrangement for application in the oil and gas industry.
