Guinea Alumina Corporation has used simulation to support the development of the Guinea Alumina Project in Guinea, West Africa.
Guinea Alumina Corporation has used simulation to support the development of the Guinea Alumina Project in Guinea, West Africa. Simulation has been used to evaluate capital options, test operating rules and to understand the key drivers of capacity risk due to variability in the supply chain.
The alumina supply chain model encompasses the bulk materials handling operations associated with the refinery at Sangarédi and port operations at Kamsar. This includes the production of export of alumina as well as the consumption and import of raw materials for the refinery. The capacity and operational implications of each component of the supply chain was considered including import and export shipping, harbour, port operations, rail transport, refinery alumina and raw material storage and production / consumption at the refinery.
Simulation was used to assist the design team in defining:
- Alumina and raw material storage requirements at the port and refinery;
- Loading and unloading infrastructure at the refinery;
- Train operating philosophy and rolling stock requirements;
- Import and export infrastructure at the port; and
- Channel dredging requirements.
The model was also used for a range of strategic ‘what-if’ scenarios and sensitivity analyses to assist in risk management and option planning. These included issues such as the implications of third party operator entry and expansions on shared port and rail infrastructure and the sensitivity of system capacity and performance to vessel size mix and arrival variability.
