Weathering properties of the Trestakk oil - Final versio

Abstract

A study of the weathering properties of oil from the Trestakk field has been performed. The data from the laboratory study is used together with the SINTEF oil weathering modell to predict the behaviour of Trestakk crude at sea. The weathering properties are discussed in relation to oil spill response both based on mechanical recovery and chemical dispersionUse of dispersants:Laboratory testing has shown a high potential for use of chemical dispersants. The time window for using dispersants can be as wide as several days depending on weather condition. Mechanical recovery:Efficiency of mechanical recovery is expected to be high. Recovery efficiency of offshore weir skimmers (e.g. NOFOs Transrec Skimmers) will not be limited by viscous emulsions of Trestakk crude.Trestakk has a very low pour point and it is not likely for this oil to solidify in scenarios with calm sea and very high evaporative loss.
