Statoil - Optimizing the Spare Parts Inventory for a Gas Turbine Pool

Spare parts pool for gas turbines on offshore platforms was optimized and cost-estimated using OPUS10.

Statoil uses gas turbines to generate electricity on most of its offshore oil rigs. A spare parts pool was constructed for these gas turbines. The pool supplies spare parts to Statoil's own gas turbines but also to turbines owned by other companies. However, Statoil owns and manages the pool.

Systecon modeled the spare parts pool using OPUS10, the world-leading spare parts optimization tool. This analysis showed which components, and how many, should be stocked to obtain an acceptable level of risk of component shortage at the lowest possible cost.

Membership in the pool requires a commitment to invest in new components. The size of each member's contribution depends on the capacity installed. A model for how to allocate investments in the spare parts pool to the participating oil companies was also created and used in conjunction with the optimization results.
