ISBL/OSBL?
ISBL/OSBL?
(OP)
This may be a dumb question for you people, but can someone explain the terms ISBL/OSBL? I know they stand for inside/outside battery limits.

RE: ISBL/OSBL?
Early oil refineries consisted of batteries, or groups, of batch stills. The term inside battery limits became associated with the equipment in that area. Everything else needed to support the operation became known as outside battery limits. It may go back earlier than that. There were rows of steam boilers at drilling sites. Perhaps they were known as batteries.

I always know the meaning for In Side Battery Limits and Out Side Battery Limits, but never imagine the full explanation.

I'm not in the chemical process industry, so these were new terms to me.
For the purpose of my own understanding, then, is it safe to conclude that 'battery limits' in the context of cost engineering are the direct and indirect costs related to the process (IE, process structural supports, piping, process controls, DCS, field instruments).
And in other words, you have your 'major equipment' and everything else to hook up the major equipment to make it work (piping, controls, instrumentation, structural, mechanical, electricals) are covered in ISBL/OSBL factors.
