Management of electrical equipment obsolescence at oil & gas industrial facilities

This paper presents the experience and lessons learned in the development and implementation of an electrical equipment obsolescence management program at a large oil & gas company. A methodology was developed to identify obsolete equipment by a rational application of obsolescence criteria and ranking mechanisms. Major investment in replacing aging electrical equipment is required to ensure operational continuity and reliability, and to assure the continued viability and cost-effectiveness of existing Company's assets. Key strategies to develop successful strategic planning for capital investments in existing facilities are outlined. The obsolescence management program is contributing to minimizing or deferring capital expenditures in replacements by cost-effective alternatives that will extend the economic life of electrical equipment, while maintaining the required operational safety and availability.
