Oil Spill Viability Analysis Online Tool
Phase II of the project was approved at EPPR I 2018 in Helsinki and is part of the follow-up to the AC Framework Plan for Oil Pollution Prevention (FPOPP).
Objective of the second phase was to develop a web based GIS tool, that enables the users to work online directly via computer, tablet or smartphone. Implementing new and improved metocean data that has been made available since the Phase I of COSRVA was approved at the Fairbanks Ministerial meeting in 2017 was part of developing the project in Phase II. The online COSRVA tool was developed in cooperation by EPPR, Norwegian Coastal Administration and DNV GL.

The purpose of the Phase I of the COSRVA project was to better understand the potential for different oil spill response systems to operate in the Arctic marine environment due to the increasing concern on the risk of oil spills as human activity increases in the Arctic.
A response viability analysis estimates the percentage of time that metocean conditions may be favourable, marginal, or not favourable for a particular oil spill response system. The COSRVA report considers the combined effects of wind, waves, air temperature, wind chill, sea ice, superstructure icing, horizontal visibility, and daylight/darkness on 10 marine oil spill response systems. Those systems represent 9 examples of proven mechanical recovery, dispersant, and in-situ burning response systems currently in use somewhere in the Arctic region. The tenth system analyzed, in-situ burning with herders, is currently under development.
