RAMS | Reliability, Availability and Maintainability Study

 

Engineering Safety LTD

RAM analysis can be applied at various stages of the life cycle.

Pre-FEED (i.e. design conceptualisation) – RAM analysis can be used to compare various design options that are being considered through quantification of the production output of each option.

Conducting a RAM analysis at this stage, whilst the design is still being finalised is known to reduce the cost and schedule impact on the project than if conducted at a later stage.

FEED – At the FEED stage, critical equipment’s are identified which could cause significant production losses. A RAM analysis would normally be conducted on these critical equipment’s in order to optimise the equipment configuration and identify the requirements of any further spares or equipment redundancies in order to optimise the availability of the system.

Detailed Engineering – At the detailed engineering stage it is likely that the design is frozen with minimal changes. A RAM study at this point would allow the client to identify performance targets that must be met by the equipment, which can be used as part of the equipment design specification during procurement.

Process Operation – Whilst the process is in operation, conducting a RAM study using the data of the as-built facility can bring the benefit of identifying unreliable equipment which are leading to production losses.
