Definition of "user" under code
Definition of "user" under code
(OP)
Hi
I am trying to understand the responsibility of my EPC firm with respect to the obligations in the code. I found the use of the word "user" to define obligations, and looking at appendix NN, there is a sort of definition and even examples of how to interpret the obligations.
However, it seems no too clear to me, so I would appreciate a clarification of who is the user for a case in which a company owner and operator of a plant, hires a EPC company to do the expansion of their plant, which include the design and supply of pressure vessels, which are purchase from a third party by the EPC company. Is the owner in this case the "user"?
Thanks in advance.

RE: Definition of "user" under code
In other words, others, or a third party, anybody but owners, operators and users, refer to the fabricator, or a equipment dealer, or service supply contractor, supplying to the EPC-owner-user. Even though in actuality the EPC may ultimately be supplying the stuff onward to the owner, the EPC is considered the owner, because he is acting on the owner's behalf when procuring these materials, equipment and services.
If that still doesn't work for you, I suggest you inquire at your company's legal department.

One clarification from what you wrote... You were not hired to perform the design of the vessel - that is the sole responsibility of the manufacturer of the pressure vessel. Although contractually you may be reviewing the manufacturer's calculations and may have contractual obligations thereof, from the perspective of the Code, the responsibility of the design (calculations, drawings, etc) are the manufacturer's.
