Oil Spill Model and Response System

OILMAP is an oil spill response and contingency planning tool that predicts the movement of spilled oil.

OILMAP is a comprehensive 3D model that tracks various hydrocarbon components on the water surface, in the water column, and in the air. The first version of OILMAP was delivered over 20 years ago and is now used globally by major oil companies and international governments. It has been used successfully to support spill response, planning, and permitting in over 100 countries.

The OILMAP v7 model has undergone major updates to include new algorithms, integrating years of applied research and consolidating experience from real events such as the Deep Water Horizon oil spill in the Gulf of Mexico. The scientists and researchers at RPS ASA have incorporated lessons learned and new technologies into the latest generation of OILMAP.

OILMAP Modules
Trajectory and Fates – 2D & 3D Deterministic Modules
  • Oil released at the surface or in the water column
  • Calculates instantaneous spills or continuous releases
  • Backtrack mode evaluates the source of a mystery spill
  • Includes algorithms for spreading, evaporation, emulsification, entrainment, oil-shoreline, oil-reed bed, and oil-ice interaction
  • Calculates surface oil thickness and concentrations in the water column
  • Integrates response options such as booming, dispersant application, and skimming
  • Animation of oil trajectories, identification of shoreline impacts, graphical and tabular listings of weathering mass balance
  • Export of model results into GIS formats for interoperability
OILMAP Deep – Seabed Blowout Module
  • Simulates near-field dynamics of subsurface continuous releases of oil and gas
  • Calculates plume characteristics and plume evolution through the water column
  • Calculates oil droplet size distributions and trapping height associated with release
  • Simulates subsea dispersant application
  • Near-field results seamlessly integrated with the Trajectory and Fates Module
AIRMAP – Air Dispersion Module
  • Simulates 3D transport and fate of evaporated oil into the atmosphere
  • Integrates seamlessly with the results of the Trajectory and Fates Module and associated meteorological data
  • Provides spatial and time varying predictions of atmospheric hydrocarbon concentrations
  • Calculates various time-weighted averages of atmospheric concentrations for evaluating hazardous conditions
Stochastic – Risk Assessment & Contingency Planning Module
  • Calculates probability and time contours of oiling on water surface, in water column, and on shoreline
  • Determines most likely spill paths for spills on a monthly, seasonal, or annual basis
  • Determines worst case conditions based on maximum shoreline oiling and minimum travel time
