	Data acquisition and processing tools have reached the point where Continuous Online Monitoring (COLM) of equipment is possible and cost‑effective.

COLM also provides valuable insights into equipment health that may help to detect incipient failures before major equipment damage.

==Description==
Data acquisition and processing tools have reached the point where Continuous Online Monitoring (COLM) of equipment is possible and cost‑effective. COLM can be used to transition from time‑based preventative maintenance (PM) to condition‑based maintenance (CBM), which reduces maintenance costs by eliminating or reducing premature maintenance activities. COLM also provides valuable insights into equipment health that may help to detect incipient failures before major equipment damage. This MTA applies to the monitoring of pump components and the associated time‑based tasks that can be replaced, partially replaced, or have their intervals extended with the use of condition‑based maintenance.

Pumps considered in this MTA are various vertical, horizontal, and positive displacement pumps. These components require routine inspection and maintenance (e.g., boroscopic inspection and refurbishment) which are historically performed periodically, regardless of operating history. Implementation of pump COLM could allow for the extension or elimination of existing maintenance activities. COLM of essential pumps can protect plant health due to their critical functions and high energy consumption (e.g., circulating water pumps).

The MTA excludes: Motor, Motor/pump coupling, Seal water injection systems (if applicable), and External bearing cooling systems (if applicable).

==Benefits==
===Benefits Estimate===
Level 1 – Savings associated with one unit implementing pump COLM are less than $1 million per year from reducing or partially eliminating PM tasks.

Additional benefits (> Level 1) may be experienced if COLM aids in successfully avoiding a component failure.

===Benefits Description===
* Reduction of maintenance costs through eliminating or extending PM tasks by transitioning to CBM. As an example, boroscopic inspections and refurbishment could be done based on pump condition as opposed to set intervals.
* Early detection of pump degradation (e.g., packing or seal wear), resulting in reduced equipment forced outages and corrective maintenance (CM) costs.
* Improved visibility to the condition of the pump(s) and associated system(s) through more frequent data collection and real‑time monitoring.
* Maintenance error reduction in the form of avoided costs.
* Reduction of radiation exposure by reducing frequency of instrument calibration.

==Costs and Schedule==
===Cost===
Level 3 – Implementation cost is less than $1 million, including sensors (up to 30 sensors recommended for each pump), installation, and software. This cost can be shared site or fleet‑wide if other components implement OLM.

===Schedule===
Six months to two years, which includes planning and implementing new sensors.

===Scope Context===
The scope of the cost and benefit estimates assumes 40 pumps per unit. Efficiencies gained from larger deployments, such as multi‑unit sites, will increase savings.

==Risks==
IT risks associated with integrating the existing plant network infrastructure, data storage, and software. Addressing IT concerns at the requirements phase of the project (for example, how the sensor data will be gathered and used) will mitigate this risk.

Sensors can vary in implementation difficulty and cost.
