A Standard for Power Plant Equipment

All equipment standards are determined by the plant owner specifications/requirements and the type of power plant.

You cannot get any accurate answers from any forum on this subject but you may get some valuable insight.

If you are replacing existing equipment:

1) You must replace equipment with "equal-to" or "better-than" quality equipment.

2) All replacement equipment must be a direct replacement that does not require major installation modifications.

3) Energy savings should be considered when purchasing replacement equipment however there must be a cost analysis performed to determine if the energy savings will provide enough savings to offset the purchase price and installation costs.

4) You must not cross substitute replacement parts from one manufacturer to another unless you absolutely know there are not any compatibility issues.

5) Proprietary parts are not usually interchangeable from manufacturer to manufacturer.

6) If a substitute part is being considered you must take the time to compare all specifications including performance and component physical size to ensure all safety aspects are complied with at all times.

7) Get input from and listen to plant engineers and maintenance personnel before listening to vendors & sales people.

8) If there is severe disagreement between the vendors/salespersons and plant personnel, arrange a conference between the two to solve the disagreement before purchasing any parts.

I agree with the others. Let the end user specify the details. I work in heavy industry and our procurement and stores spent a lot on detailing our equipment using the NATO system. It's really difficult finding parts because they simply didn't use the manufacturers detail and tried to make it generic. As above the equipment usually cannot be interchanged and you simply need to document what you have and let the end user sign the PR. Good luck.

"procurement division" means to me that you are employued in quite a large organistion. Your user Departments must be made responsible for the full and proper purchasing description, for both stock and non-stock items.

The buyer cannot be made responsible for the certification requirements of any item.That is why you have technical departments and engineers.

Anyone who tells you different is just ignorant.

I really like your logic and reasoning but many companies dump the entire responsibility for controlling all facets of purchasing any/all materials, replacement parts, and services on their buyers and they expect/require the buyer(s) to do the research.

The company I work for is a very large international company and they have this very same policy in place.

It often causes severe lost production time, high overhead cost, and a great deal of frustration to everyone involved.

I feel sorry for the buyers as they in no way have the knowledge to do all that is expected of them.

As you can imagine we have a high turnover rate of employees in the buyer GS division.
