Thanks for the feedback Noman!

Thank you for this awesome video. If I understand well, hydrostatic tests are part of the pre-commissioning. Could it be that Mechanical Completion comes after pre-comm? How far does the commissioning go? Can it start-up the whole plant or could it be that the client makes the final steps of the commissioning to check that all the systems work well together and that the General Contractor stops after having checked big systems of the plant? Thank you.

[@commissioning]

All very good questions, and the answers are all very project specific based on the contracts. Hydrostatic tests are part of pre-commissioning and are often done by the installer prior to MC. Further pre-comm then takes place after MC. There are lots more free resources your can check out on our site www.commissioningandstartup.com

@@commissioning Thank you for your answer :) In the pharma industry there are commissioning > qualification > validation. Have you already worked on a pharma project?

[@paulcarsonturner]

Yeah, pharma uses CQV. Different terminology, same concepts. Wouldn’t it be great if there was a standard set of terminology used across the commissioning industry? I haven’t worked on a pharma project.

In term of project planning and schedule, do you recommend to further divide the Work Breakdown Structure (WBS) to Cosntruction, Pre-Commissioning and Commissioning or better to divided it into system and subsystem?

[@commissioning]

Better to divide into subsystem and system. Individual equipment of each subsystem will undergo pre-commissioning, then be tested as a system during commissioning.

[@yazidsalehuddin7633]

@@commissioning Agree with you. As much as i had the same thinking like you but in reality most of the project plan and schedule nowadays still divided the WBS by Construction, Pre-Comm and Comm instead of by system and sub-system. I see that the main reason is because usually Construction phase and Commissioning phase usually will be excuted by different people/organization. Maybe in the video you can explain and maybe show one good example of how the project WBSby systemization

[@commissioning]

@@yazidsalehuddin7633 You're right, and this can be a cause for confusion as the project transitions from construction to commissioning. The construction team will focus on installation of each individual piece of equipment, as they should. But the thought process needs to change and focus on groups of equipment as a system. One piece of equipment is not very useful to the commissioning team on it's own - several pieces if equipment as well as cables, piping, etc are required to function as a system. The Commissioning Team can help with this transition by having very well defined Mechanical Completion documents.

many thanks is a good video for commissioning please speak slowly in case i can understand what you speak.

[@faizthakur5832]

You can slow down video speed if you think u ain't able to understand.. Go to play back speed.

[@user-yl8qd4hw1p]

Pre-commissioning is called mechanical completion, right?

[@paulcarsonturner]

No. Mechanical completion (or static completion) is the milestone before pre-commissioning indicating that construction is complete (static installation is verified) and that pre-commissioning (functionality) testing can begin.

[@instengineer815]

Mechanical completion is where the Construction team gives the "key" to the Comm team and says "that everything is installed as per specs, it is tested and passed, and you can proceed now; that is your baby."

[@dingintsibande7367]

How long does it take to perform each test; pre-commissioning and Commissioning process?

[@commissioning]

That will depend. Each specific test will take time, depending what is being tested. Some tests will take days, some tests will take minutes. The overall pre-commissioning and commissioning process on a large project can take many months.

Hi does one take the test ?

[@user-yl8qd4hw1p]

I don't understand how FAT can confirm no damage during shipping. Anyone who can clarify this?😊

[@paulcarsonturner]

It won’t, FAT results are compared to SAT results to confirm no damage during shipping or installation.
