Maintenance Risk

摘要

Every power generation manager is a risk manager balancing maintenance spending, technical performance and un-availability to maximize the financial performance for their assets. To combat this risk, companies employ a variety of different management strategies. Solomon developed its maintenance risk methodology to both describe maintenance effectiveness and provide a means of communication throughout the organization, allowing for the greatest potential improvement. The methodology involves a visual framework that focuses on the risk of sub-optimization of the financial and technical performance of the asset rather than merely emphasizing one aspect such as reliability. Solomon's experience suggests that seldom do companies reduce risk by reducing severity (costs) first, primarily because there tends to be an underlying frequency (unavailability) issue that is driving the higher costs. Cutting costs would likely only exacerbate the problem. Unavailability should typically be addressed first, even at a higher, near-term cost to allow the generator the best chance of reducing costs in the long term.
