What availability should the plant have? Should additional investments be made to increase the plant’s availability? How can you be sure those investments would actually pay off? How do technical design choices made now impact operational costs many years into the future? These questions can be answered by a systematic analysis of the system.

RAM refers to Reliability – Availability – Maintainability. Together, these three concepts are the foundation of the notion of dependability – a central concept in the energy industry. High dependability is a prerequisite for a well-functioning system with a minimal number of kilowatt hours lost. To achieve the lowest possible life cycle cost (LCC) without sacrificing system performance, the three RAM concepts should be considered over the entire life of the system, and the right level of dependability specifications should be formulated.

Identifying these specifications and analysing how well a sub system must operate in order to achieve the promised overall system performance, is one of Systecon’s areas of expertise. Systecon has worked on dependability and its relationship to life cycle costs for many years, in part using our own software but also relying on established industry standards and practices.
