Origin and fate of hydrocarbons in Sullom Voe

Abstract

SynopsisThe results of chemical analyses for hydrocarbon components in the surface water film, water, sediment traps and sediments are presented for samples collected during the period 1973–78. The n-alkane profiles of these samples are used to characterise the hydrocarbons and to help in determining their origin. The amounts of hydrocarbon present are compared to the estimated inputs of petroleum hydrocarbons from operational losses and accidents based upon analogies with worldwide averages and with data taken from other similar oil terminals. Some conclusions are drawn as to the likely fate of this oil in Sullom Voe.
