Operational Readiness and Maintenance Strategy Development

For years, AOC consultants have been delivering sustainable and reliable asset performance management programs to ensure operational readiness based on RBI (risk-based inspection) and RCM (reliability-centered maintenance) studies. Our successful approach aligns your people, processes, and technologies so that you implement best practice risk-based work processes and increase the design life of your assets months ahead of RFSU.

People

Our learning management approach strengthens a sense of ownership in your personnel through the systematic transfer of knowledge of training, human performance improvement, work processes and technology. As a result, you are equipped to implement best practice risk-based work processes and to increase the design life of your assets months ahead of RFSU.

Process

We begin with the end in mind: OME (Operation, Maintenance and Engineering) services end when the EPC (Engineering Procurement and Construction) contractor hands the plant over to the Owner following acceptance of the performance test. We work proactively with you and your EPC to develop maintenance strategies for operational readiness, optimized recommendations, and activity plans during EPC to facilitate the activities of the contractor and Owner prior to and after plant handover.

A simplified overview of that process is as follows:

This process includes the analysis of equipment types to develop a Risk Ranking for each inspectable component. A consequence of failure (CoF) analysis is performed based on safety/environmental implications from loss of containment as well as production loss models to approximate business interruption. An estimate of the probability of failure (PoF) is based on the identified degradation mechanisms and deterioration rates affecting the equipment.

For rotating assets and components, we use FMECA and RCM techniques to determine failure modes affecting the asset. Since these techniques are resource intensive, a prioritization scheme is developed so that only the most economically critical assets/components are analyzed. For example, a preliminary approach might be based upon power of the rotating driver as follows:

• Assets/Components greater than or equal to 500 hp will be analyzed using FMEA.
• Assets/Components less than 500 hp but greater than or equal to 50 hp will be analyzed using RCM.
• Assets/Components less than 50 hp may not be analyzed at all but follow standard manufacturers maintenance recommendations.

Technology

Our consultants help to select and populate data into your CMMS and AIM (asset integrity management) software solution using technologies such as Intergraph's Smart Plant and Fusion to facilitate data migration from those "sources of truth" to the target database of those selected technologies. If these technologies have yet to be selected, we deliver one map that aligns all of the requisite manufacturing, design and operating data into an ISO 14224 compliant database.
