Reliability, Availability and Maintainability

Given growing competition from world markets, an ever-present drive to reduce cost and increase profits, businesses are being forced to seek more effective methods for the management of their assets. PT WIDE & PIN place great importance in ensuring our clients are fully aware of the true quantifiable benefits likely to result from the adoption of a particular strategy or the introduction of new technology.
To achieve this DNV-JARDINE use a Risk Management approach, incorporating a blend of independence, specialist technical experience, and advanced reliability techniques and software tools. This allows us to rapidly identify areas of potential improvement in a client’s business and to investigate and demonstrate the merits of alternative business solutions. Our clients therefore have the opportunity to:
  • Optimize their business strategy and mitigate potential risks in advance of any significant investment
  • Qualification of new technology
The nature of a RAM analysis will vary according to the purpose of study and the scope of work. However, in any case, the RAM analysis will predict system availability and identify ways to improve system availability. Competing solutions can be investigated on the basis of quantitative benefits. Improved system availability can increase the overall business performance if the additional cost associated with the improvements is lower than the increased revenues. Therefore, the RAM analysis can be used to optimize a production system from a cost/benefit point of view.

    Production Availability and its influence on Cash-Flow
  • Component failures reduce revenues and increase operating expenditures (OPEX). The RAM analysis is a tool to assess the financial consequence of component failures and to identify ways to improve profitability (increased revenues and/or reduced costs). System availability performance has an influence on all major cash-flow elements:
    • Optimize Revenue stream
    • Operations and maintenance expenditures (OPEX)
    • Capital expenditures (CAPEX)
    Work Process
  • The main elements of a RAM analysis are:
    • Establish what is critical to the asset (baseline model)
    • Benchmark to historical performance
    • Optimize through evaluation of alternative design, maintenance, logistics, operations and sales strategies
    • Develop new Key Performance Indicators (KPI) for continuous improvement
    Software
  • TARO
    The TARO simulator developed specifically for the modeling of refining and petrochemical plants in which the production (gasoline and derivatives) efficiency is a complex interaction between reliability, blending and yield rules, flow routing, and intermediate storage options.
    MAROS
    MAROS predicts system effectiveness in terms of reliability, availability, and productivity. It can be used to quantify the life-cycle cost effectiveness of a system, and conduct optimization to improve profitability. MAROS is a well tried and tested package, first used in 1984, and subject to continuous improvement and development.
