Course Overview:
Process Unit Operations & Maintenance of process plant and equipment presents both a major technical and management challenge. With this in mind, this program addresses the technical issues of commissioning, starting up, unit Operations and maintenance of various equipment and asset types commonly found in processing plant environments, process, and facility.
This course is designed to provide participants with an up-to-date overview of the Process Unit Operations & Maintenance of Process plants including troubleshooting of the start-up process. It includes the methodology for Process Unit Operations & Maintenance of process plants which can be used when commissioning a new plant or for modified equipment in an existing facility, or in a turnaround shutdown or overhaul scenario and normal plant operations. It takes the approach that commissioning is a series of checks and counter-checks to confirm every unit in the process plant is fit for purpose and suitable for operation.
During the course, each participant will gain enough skills to anticipate and avoid problems associated unit Operations and maintenance. Participants will gain a satisfactory understanding of the unit Operations and maintenance strategy, organizational issues, estimation of required resources, mechanical integrity, troubleshooting, start-up operations, technical inspection, instrumentation control systems, HSE and other necessary knowledge associated with the process plant start-up , Operations and maintenance.
Actual case studies from around the world will be demonstrated to highlight the topics discussed.
