| Non Destructive testing (NDT) |
|
Any material testing that doesn’t
destroy material. During the testing process. Note:
Usually we think of Ultrasonic Thickness Testing. Also included in
NDT is usually dye-penetrant testing, x-ray testing, and electrical
resistance testing. Vibration, thermography, look, listen, feel, smell,
winding test etc are not included since they are testing components,
and equipment, not material. |
| Non-Scheduled work |

See unscheduled work |
| Off-line |

is down it’s considered an outage, or shutdown/ Turnaround. |
| Oil Analysis |

Testing of oil in order to find failures

| Operate To Break-Down (OTB) |
|
A maintenance strategy which operates equipment
until break-down. A maintenance strategy which sometimes can be the
most cost effective. Note: OTB is used when
the consequence of failure is small enough that the benefit of preventing
or finding failure early is more costly. OTB will be the fact for
failures that occurs randomly and have no failure developing period. |
| Outage |
|
A shutdown/ turnaround that affects the
whole plant for more than 16 hours. |
| Overall Production
Efficiency (OPE) |
|
The product of Quality
[%] * Speed [%] * Uptime [%] for a production line. |
| Overall Reliability |
|
See Production Reliability |
