Optimizing Equipment Maintenance and Replacement Decisions

Introduction

Major world companies from the process and petrochemical industry have developed their maintenance practices based on the optimization of predictive maintenance management system. This approach works well for both stationary and rotating equipment and includes continuous condition monitoring and the detailed inspection of vital elements of the equipment. The optimization of the maintenance activities includes the spare parts handling, the selection of the right size and skill of maintenance crew with consideration of potential outsourcing i.e. subcontracting. Based on the collected data on the reliability of the equipment in operation, the Maintenance department can complete the Fitness for Service analysis based on which the decision can be made about 3Rs: Run, Repair or Replace, for the particular component of the equipment. The final decision regarding equipment replacement depends very much on the economic and safety aspect that must be taken into consideration. 

This Optimising Equipment Maintenance & Replacement Decisions training course is intended to introduce the participant to the process of making decisions regarding equipment maintenance optimization including equipment replacement. Various optimization techniques will be presented and the optimization criteria explained. This training course will include several workshops with case studies and real-world problems to be solved. This will enable all participants to actively take part in teamwork and classroom discussions.

This training course will feature:

• Main Types of Equipment Failure Mechanisms
• Maintenance Methodologies and Economic Aspects
• Spare Parts Handling and Storage Modeling
• Risk Assessment and Management       
• Equipment Inspection and Fitness for Service Analysis

Objectives

By the end of this training course, the participants will be able to:

• Identify equipment failures and the impact on plant reliability
• Understand the cost-effectiveness of Preventive / Predictive Maintenance program
• Apply techniques of optimization of various maintenance activities
• Define criteria for work-crew size, spare parts and equipment replacement
• Make the important decision on the basis of the cost and benefit analysis
• Incorporate safety objectives to the equipment repair or replacement optimization

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations.
