Abstract
Numerical simulation of the consequence of oil pollution taking into account
human response is an important tool for the planning of spill recovery strategies.
Considered here is a structure of such a system developed by TRANSAS. The
model uses a particle tracking method for the description of an oil slick affected
by oil transport by sea currents, buoyancy and random diffusion caused by the
vertical and horizontal turbulent mixing. The model also includes simulation of
weathering processes such as evaporation, dispersion, emulsification, burning
and viscosity variation. Different types of oil spills are considered and can be
computed simultaneously. The program implements a method for the easy
collection of coastline descriptions from vector-based nautical charts, and
construction of the fields of currents from tidal and surface current databases.
Special emphasis is laid on the modelling of response resource application
including booming and recovery.
Keywords: oil spill simulations, response strategies.
1 Introduction
Response planning and recovery strategies associated with oil spills in coastal
waters require the availability of efficient and flexible high-speed methods for
forecasting the oil spill distribution.
The on-line simulation system described in this paper is intended for
modelling of different response strategies and is based on the Lagrangian
approach to the oil slick description, which is an effective technique of oil spill
numerical simulation. In this context, the oil spill is represented by an ensemble
of particles moving independently under the effect of wind and current. The
chemical processes occurring in the oil slick are also taken into account and
