Operation and Maintenance

A. Operation

Operation means a state of working or being able to work, or a way or process that parts of a machine or system work together smoothly to produce goods.

Plant Operation is to operate and control of the plant ensuring efficient, safety, and reliable process operation

Operation Readiness is the process of preparing the custodians of an asset under construction organisation to the client operation organisation, at the point of delivery and handover, the client is fully prepared to assume ownership of the asset, accepts responsibility for performing the safe and efficient operation of that asset. The Operation Readiness is the management practices for performing pre-start-up reviews of new processes or processes that have been shut down for modification, and processes that have been administratively shut down for other reasons. These practices verify the operational readiness of a process and help to ensure that the process is safe to restart. Identifies organizational tasks, roles and responsibilities, assists with start-up and operations and maintenance, focuses on high priority risks, and analyses opportunities.

Operability is an ability that the process has the capacity and flexibility to achieve a range of operating conditions safely, reliably, profitably and with good dynamic performance and product quality. The Operability ensures to keep an equipment, a system or a unit and plant in a safe and reliable functioning condition, according to pre-defined operational requirements.

B. Maintenance

Maintenance is an activities performed on an item to minimize the possibility of damage or the lowering of quality because of corrosion, contamination, or deterioration for the continuous operation

Maintenance Readiness is a maintenance programs that covers the maintenance team for start-up, ramp-up, and ongoing operations.

Maintainability is defined as the probability of performing a successful repair action within a given time. In other words, maintainability measures the ease and speed with which a system can be restored to operational status after a failure occurs. This is similar to system reliability analysis except that the random variable of interest in maintainability analysis is time-to-repair rather than time-to-failure.

C. Turnaround

Turnaround is a scheduled period of non-production within the plant. That means that day-to-day operations cease completely during the duration of a turnaround and instead the focus shifts to maintenance related activities, cleaning, inspection, and repair. During this time the plant’s employees, and often outside contractors, work around the clock to get everything ready for the plant or unit to resume its regular operations. Speed is of the essence when it comes to shutdowns because they are extremely expensive in terms of production lost, increased labor and equipment expenses. (Source: http://setxind.com)
