Reliability, availability and maintainability (RAM) Another comprehensive method is the reliability, availability and maintainability analysis, in other words, system modeling. SKF uses proven RAM methodology to provide an integrated analysis of expected system performance based on system design, operations and maintenance. RAM models are used to evaluate reliability issues around specific equipment and/or systems focusing on the cost implications through cost/benefit analysis of proposed changes.

Reliability, availability and function test interval (RAFTI) calculator: This tool makes it easy and convenient to automatically determine equipment availability, reliability and function test intervals to increase reliability of the overall system. The calculator allows the user to evaluate the resulting Function test interval (FTI) given a desired reliability and Mean time between failure (MTBF) or calculate availability given a desired FTI and MTBF.

Reliability engineering: Reliability engineering collects and analyzes data to either predict future reliability or to determine the causes of past unreliability to help prevent their recurrence. SKF uses proven reliability engineering approaches to identify and coordinate critical elements to help improve key asset reliability. These include an effective maintenance and implementation strategy; quality data capture and retention; the ability to determine key plant or equipment failures; a structured repeatable method of failure analysis and a method of capturing and implementing analysis recommendations. The reliability engineering approach also provides a closed-loop framework for organizational learning – all of the information gathered and developed during the model’s implementation is fed back to the starting point to refine the strategy. SKF consultants deploy industry-standard statistical analysis techniques such as reliability growth, probability distribution and the cost of unreliability.

Root cause analysis (RCA): Root cause analysis seeks to identify the sequence of events leading to failures and creates a plan to help prevent future failures. The SKF service is based on the theory that every failure stems from three causes: physical or technical causes; human causes such as errors of omission or commission; latent or organizational causes that stem from the organization’s systems, operating procedures and decision making processes. After investigating each category, SKF delivers a set of causes and effects plus a comprehensive plan of corrective actions to prevent recurrence.

Life cycle costing (LCC)  The life cycle cost of any asset is the cost of acquisition plus the total cost of ownership, including operation and maintenance costs. An SKF Life cycle cost analysis determines the future value of maintenance engineering decisions made while developing a maintenance management system. The LCC is associated with the total cost of ownership because by the time the maintenance system is under development, the design is complete and the asset is usually in the construction phase with 60-70 % of its maintenance costs already built in. However, significant cost savings can still be achieved by optimizing the maintenance required to meet the asset’s defined business goals, reliability targets, and production profile. An SKF LCC analysis compares a variety of scenarios for the asset to determine the best return for a given investment profile.
