TransAT-Spill is a plume model designed for
use in environmental risk assessment and oil
spill contingency planning in conjunction with
petroleum exploration or production in deep
waters. It tracks oil and gas from a subsea oil &
gas spill in a coupled way, combining an
Integral Plume approach near spill, with a Far
field oil droplet, gas bubble spill Lagrangian
tracking. The Lagrangian Integral Plume model
is coupled to TransAT above the neutrally
buoyant layer to track gas bubbles and oil
droplet trajectories in 3D, using the sea-current
data. Dispersion of the droplets by small-scale
turbulence is modelled using a deconvolution
approach.
