EPConsult Energies Nets Substantial Savings for Tullow via RAM Assessment

Production optimization of existing fields and improving the profit margin of new developments is a complex challenge for the oil industry especially in a ‘lower for longer’ environment.  In recent years production availability has become so important that it can be a key selection criterion when determining whether to proceed with a new Field Development.

EPConsult Energies have recently completed a Reliability Availability and Maintainability (RAM) Assessment for Tullow’s South Lokichar Development in Kenya which has resulted in substantial savings.

RAM analysis is typically used to predict the performance of an oil or gas production system and to provide a basis for production efficiency and optimisation. 

RAM can support the conceptual selection process for new projects or improve the efficiency of existing assets.

The findings of a RAM assessment can create significant value as it can provide:

  • Insight into the most critical equipment and systems in the plant
  • Optimisation of spares holding
  • Guidance as to how logistical challenges can be improved


The methodology of RAM modelling is as follows:

  • Data gathering via industry reference source data such as OREDA, operator experience and past project experience
  • Preparing an inherent availability model which does not include any planned maintenance constraints
  • Reviewing the critical analysis to understand which items are most critical
  • Preparing an operational model using data on manning, sparing and logistics
  • After the initial operational model is complete various sensitivities can be performed to optimize sparing philosophies and maintenance strategies.

EPConsult’s extensive experience in RAM assessment means that we have developed a substantial database of reliability and operational data which we can use to benchmark results.
