Abstract:

Contamination of the seabed by drilling operation discharges and the potential for accidental oil spillage remains a significant environmental concern. A project commissioned by Elf Caledonia Ltd. has led to the development of a series of models that allow assessment of the environmental impact of contaminants associated with offshore drilling and prediction of possible oil spill scenarios. Three environmental modelling systems have been implemented. A current flow prediction system has been set up to provide a primary source of data on the hydrodynamics of the region. An oil spill model allows prediction of the trajectory and fate of oil in the event of an accidental spillage. The third model considers the drilling mud and cuttings discharges made during exploration. The three models use the same base set of hydrodynamics/bathymetry and run under the same base GIS user-interface. This paper discusses the development of the various databases underlying the models, development of the models and the use of the models in planning the drilling programme. Development of models for future applications is discussed.
