Mechanical Integrity – Rotating Equipment


Reliability centred maintenance (RCM) is a methodology that enables the definition of a complete maintenance strategy for rotating equipment. It regards maintenance as the means to maintain the functions an operator may require of machinery in a defined operating context. It enables equipment operators to monitor, assess, predict and generally understand the working of that equipment item. Initially the RCM process identifies the operating context of the equipment through a Failure Mode Effects and Criticality Analysis (FMECA). Following this, “RCM logic” is applied which helps determine the appropriate maintenance tasks for the identified failure modes from the FMECA

Reliability centered maintenance (RCM), emphasizes the use of predictive maintenance (PdM) techniques in addition to traditional preventive measures. RCM provides  a tool for achieving lowest asset Net Present Costs (NPC) for a given level of performance and risk.

Ankaa Consulting perform RCM based on SAE J1011 and J1012 standards through the following processes:

  • Failure Mode Effect & Criticality Analysis
    • Either using FMEA or FMECA
    • Workshop type or utilizing OREDA database information
  • Identification of SCEs and development of Performance Standards
  • Development of Maintenance Strategies
  • Optimisation of Maintenance Programs

In addition to RCM, rotating equipment services also extend to:

  • Development of Asset Equipment Tag Register in accordance with ISO 14224
  • Development of Condition-based Maintenance Plans
  • Development of Specific Equipment Reliability Plans (SERP)
  • Spare Parts Optimisation Studies for operational, critical & insurance spares
  • Risk Spares Analysis (RSA)

Typical rotating equipment items that can be considered include:

  • Compressors
  • Turbines
  • Pumps
  • Centrifugal fans
  • Gearboxes
  • Engines
