Most of industrial projects involve two different type of facilities: a portion inside the battery limits (ISBL), including all the process units, and a portion outside the battery limits , usually referred as off-sites, or OSBL. OSBL consists of the facilities required by the process units to operate: feed and product storage, product finishing and packaging, shipping facilities, flare system, technical buildings, raw water treatment, waste treatment, etc. Utilities and power generation are sometime considered part of the Off-Sites, but generally speaking it is preferred to refer to utility facilities separately. The design of OSBL usually does not require licence agreements but certainly it does require a specific know-how to minimize investment cost and facilitate commissioning and operation activities. Design, implementation and revamping of Off Sites are part of Energeco core business: details of Energeco capability and experience are detailed in the specific system area.
