Commissioning Plan vs Start-up Plan

[CuriousElectron]

Hi Gents,

What are some differences between a commissioning plan and startup plan for industrial/power plant projects?

Thanks,

It may be semantics. As an example, the transmission utility I work with refers to my position as Commissioning Engineer. A neighboring utility refers to the same position as Start Up Engineer. In this example the positions are interchangeable.

In industrial / power plant it may also have to do with multiple disciplines as the electrical is only one part of the overall process.

Based on the terminology I was taught:

A commissioning plan is an exhaustive / comprehensive plan for completely proving the full functionality of a new build of any kind, including that the correct settings are applied to all alarms, trips, control ranges, et cetera and so forth, performing pre-run end-to-end checks to confirm that all wiring and functionality can be proven while still in the "cold iron" state and in advance of initial first-time-ever actual live plant operation, and also for sequentially testing that, with the plant in actual operation, each and every control / alarm trip point actually controls / alarms / trips for whatever it's supposed to.

A start-up plan is the documentation based upon a known plant configuration and behaviour that incorporates all pertinent limitations on warm-up rates, etc., etc., and is the plan used in start-ups during normal/routine operations once a plant has been fully commissioned.

If "startup plan" is actually meant to mean "initial plant start-up plan", all bets are off...

Commissioning and Startup
Knowledge Area Definition
Commissioning and Startup is defined as the transitional phase between plant construction completion and commercial operations. It encompasses all activities that bridge these two phases including systems turnover, checkout of systems, commissioning of systems, the introduction of feedstock, and performance testing.
