Recently, GE Oil & Gas Global Services has developed maintenance approaches to increasing the Availability and Reliability of units based on structured planning methodologies. These new methodologies were developed and tested by the Contractual Services team, but in the last two years the Operational Performance Management organization has also had successes in applying similar techniques with customers under transactional relationships. The details of these new approaches and methods can be found in a paper published in 2009 titled "Increasing availability with lean outage excellence: advance planning and execution optimization" By Francesco Amore Bianco & Domenico Di Giambattista. This article focuses mainly on how to apply advance planning and optimal scope of work definition for customers under transactional relationships, and on the algorithms for developing long term maintenance planning simulations. The use of the methodology in the Demand-to-Inquiry and Inquiry-to-Order phases to align the definition of the scope of work and the matrix of responsibility is the main difference between the contractual and transactional versions of the same methodology. In addition, the effective implementation of planned maintenance and inspection in a transactional relationship requires a deeper mutual understanding of the internal cycle times of the two organizations (Customer and Original Equipment Manufacturer) and strong coordination, working hand in hand with the customer to align operational needs. The case addressed in this paper is a real case developed with an Algerian customer in July of this year and provides a practical example of how we applied the theoretical concepts described in this article
