Oil spill response and planning tools
There are a number of informative planning tools used in oil spill response. These tools assist in the determining of response priorities and decision making by providing information on the behaviour of oil, sensitive environments and model predictions.
Automated data inquiry for oil spills (ADIOS)
The Automated Data Inquiry for Oil Spills (ADIOS) is a weathering model used to predict how oil will break down in the marine environment. It provides response planners with an indication of how long an oil spill may persist in the environment, and the best options for clean up.
The model uses weather conditions and chemical properties of the oil (either selected from the ADIOS library or manually entered) to predict the rate of evaporation, dissolution and emulsification.
ADIOS is maintained by the US Government's National Oceanographic and Atmospheric Administration (NOAA).
Please visit the NOAA's Office of Response and Restoration's website for more information on ADIOS.

Net environmental benefit analysis/spill impact mitigation assessment (NEBA/SIMA)
A WA Net Environmental Benefit Analysis/Spill Impact Mitigation Assessment (NEBA/SIMA) Tool has been developed based on the Australian Maritime Safety Authority (AMSA) National Plan workshops and the International Petroleum Industry Environmental Conservation Association (IPIECA) guidelines.
The purpose of this tool is to aid in the selection of response strategies in accordance with identified protection priorities.

Oil Spill Response Atlas (OSRA) 2.0
The Western Australian Oil Spill Response Atlas (OSRA) version 2.0 is a spatial database of environmental, logistical and oil spill response data. Using a geographical information system (GIS) platform, OSRA 2.0 displays datasets collated from a range of custodians allowing decision makers to visualise environmental sensitivities and response considerations for both contingency and incident planning. OSRA 2.0 was upgraded in 2021 to provide additional functionality, datasets and improved user accessibility.
OSRA 2.0 is managed by the Maritime Environmental Emergency Response team within DoT Maritime and is part funded through the National Plan for Maritime Environmental Emergencies and the Australian Maritime Safety Authority.
Web Map Application (OSRA-WMA) 2.0
OSRA-WMA version 2.0 allows the layers found in OSRA to be viewed via a secure portal from the DoT website and provides basic functional tools, including the ability to print maps.
While not intended to replace the full capacity of the GIS OSRA, WMA will provide users with a functional, user friendly and accessible alternative to assist in oil spill planning and response. WMA is a secure platform and datasets provided to DoT will not be open for extraction.
Register for access
Potential users will need to register interest in accessing WMA. Registrations will be reviewed on a case by case basis and logins will be issued by DoT based on an appropriate operational requirement to access WMA. Log-ins to WMA will be limited to ensure optimum operation of the system.
Please use the registration form below to begin the process. To do this, first save the form locally to your computer. Then fill in the details and click the 'Submit' button.

Oil spill trajectory model (OSTM)
Computer-generated Oil Spill Trajectory Models (OSTM) predict the behaviour of oil in the marine environment, and are valuable tools in response and contingency planning.
The movement and weathering of oil is calculated using data from:
- Metocean currents.
- Wind forces.
- Chemical behaviours.
OSTMs are only as accurate as the data used to generate them, therefore it is important to validate the model created with 'on the ground' measurements.
Incident Management System
DoT has developed an Incident Management System to enable the effective management of an oil spill response. The System is supported by a suite of meeting agenda and forms. This material is based on the Incident Command System (ICS).
Western Australian Marine Oil Pollution Risk Assessment (WAMOPRA)
In order to understand the State's marine oil spill risk profile, the DoT has conducted a State-wide marine oil pollution risk assessment. The risk assessment was comprised of two components:
- Evaluating protection priorities of the receiving environment in order to assess potential consequences of marine oil pollution, and
- Assessing the likelihood, size, location and type of marine oil pollution.
The results of the project will be used to prevent, prepare, respond and recover from a marine oil pollution incident.
For the purposes of this project, State waters have been divided into seven zones as shown in ‘Western Australian Marine Oil Pollution Zones’. Results for the project are available from the WAMOPRA web map application.
