In order to assess how pollution from NSR shipping will impact the
environment, a statistical oil drift model has been applied to provide drift tracks of the
pollutants. The OILSPILL model is based on the trajectory concept which means
that the model simulates the drift and the weathering of the oil as individual
points of mass released at different times within the available historical time
series of wind data. Advection and loss of oil due to evaporation and natural
dispersion as well as oil stranding are the main physical processes accounted
for in the model. The oil drift statistics are obtained by repeating the
simulations of oil drift from chosen spill sites for a large number of oil spills.
A total of 14 scenarios along the coastal and the high latitude route have
been identified. For each scenario, a total of 600 oil trajectories have been
simulated. This data set contains the start position for all trajectories from each
scenario.
