The use of dispersants has a potential in ice-covered waters. The present project will improve the technology, document the effects and further improve our knowledge on how and when to use dispersants as part of an environmentally efficient solution for oil spill contingency in ice covered and Arctic areas
The main objectic of the project on dispersants will be to establish criteria for how, where and when to use dispersant in ice covered areas. The project will:
study the effectiveness of dispersants and define the “window of opportunity” for operational use of dispersants under these conditions.
evaluate existing application equipment and suggest improvement and adaption to cold conditions and presence of ice.
The most critical parameters for obtaining an effective dispersants operation under Arctic conditions are:
1. Good application of dispersant on the oil 2. Sufficient energy for the dispersion process 3. Oil properties at low temperature – weathering 4. Dispersant performance and properties under relevant conditions (salinity, temperature, oil type).
