Kindly provide me with any available information regarding hot cut-over procedures. Why do we use it, what are the different methods to do it and what are the safety precautions to be taken into consideration. Also if there is any document regarding this subject available on the web please advise the address. Thanks
Hot Cutover basically means to plan, install, commission and integrate new control systems/ electrical equipment with the existing systems without taking large sections of a plant into shutdown mode. Usually required where production should not be affected and where the modification itself is manageable to become part of the hot cutover procedure.

I do not know of any published material here but we have done it at times. It requires thorough planning and understanding of operational parameters.
