Vessel V-307 is to be replaced in a plant with a vessel that is designed to withstand a higher pressure and which has a larger volume. Should this vessel be numbered V-307 to correspond with the vessel it is replacing? Explain your answer.
Generally, the answer is No. Unless the replacement equipment is essentially identical in function and characteristics to the original equipment a new number should be chosen to avoid confusion when locating information about the equipment. For the case considered in this question, calling the vessel V-307A would probably be ok.
No, unless replacement equipment is identical; choose new number to avoid confusion. Vessel as V-307A might suffice.
