Production Availability/RAM-Analysis

Find your cost-optimal solution by input from Reliability, Availability and Maintainability (RAM) analysis

Safetec is home to a large number of experts conducting several RAM analyses each year. Our methods are invaluable in predicting the availability of your system and support decision-making for production assurance.

Why RAM Analysis?

RAM analysis is a well-known method of estimating the production availability of a system by assessing failure modes, frequencies and consequences, all the while paying attention to the effect on production. The intention is to find out if the estimated production availability meets the requirements, and to identify the most cost-efficient parameters to help pave the way for an optimum solution in terms of profit.

What we do

Our RAM team consists of experts on state-of-the-art methodology and tools. We study your input documentation, facilitate workshops, and analyse and present the results in accordance with ISO 20815. A RAM analysis can be carried out on production systems and subsystems of all kinds and sizes. Our experience lies mainly within the oil and gas industry – from subsea, topside and onshore facilities – but there are no limitations regarding industry nor complexity. We have been involved in the various project stages, like the early concept phase, the design phase and modification projects.

The scope of work for a RAM analysis is to study the system components, their capacity and configurations, reliability data, repair data, resources required, operational conditions, production profiles, etc. Each component critical for production is modeled together in a software tool, taking into account all conditions affecting the production if failure should occur. We are authorized users of three software tools; MIRIAM, MAROS, and ExtendSim.

A Failure Mode, Effect and Criticality Analysis (FMECA) is often performed as a first step of a RAM analysis. We support our customers with FMECAs in connection with RAM analysis as well as separate studies. See more info in FMECA.

Collection and assessment of reliability and repair data is a crucial part of a RAM analysis performance. We place significant emphasis on searching for and assessing the data with respect to the relevance and quality of the data.

Advantages and benefits

  • Identification of failure modes and their consequences
  • Multidiscipline workshops with focus on both local and system effects of failure and repair
  • Estimates of production availability
  • Estimates of production time with respect to demand
  • Estimates of production time above zero
  • Identification of bottle necks and “production drivers”
  • Decision support to determine the most cost-optimal solution with respect to:
    • Process design
    • Spare part philosophy
    • Mobilization times and contracts
    • Preventive maintenance strategy
    • Identification of cost-effective measures
    • Knowledge of industry performance methodology

As an extension of the traditional RAM analysis performance, we can also offer you a dedicated cost-benefit analysis, like the Life Cycle Cost (LCC) analysis. Our analysis combines the results from the RAM analysis with cost parameters of both investments, fixed costs and variable costs. A cost-benefit analysis will measure and reveal your net present value, break even price, internal rate of return etc.
