What is Simops?

Jay Stansell - Monday, October 03, 2011
Simultaneous Operations - referred to here as SimOps - occur when two or more potentially conflicting activities or process operations are being coordinated in the same location at the same time.

SimOps often occur when multiple contractors and/or a large multi-disciplinary workforce is working at a single location and in close proximity in space and time.

You are particularly likely to find SimOps whenever construction or major maintenance work is being done within a "live" process area of an existing facility.
You'll frequently find this when major expansion construction projects are underway; when new equipment is being "tied-in" to an existing plant; or during major shut-downs.

Other examples of SimOps include work involving the use of cranes over the top of live flow lines in a gas plant; or a situation where a diving vessel is working within the exclusion zone surrounding a offshore oil production platform.

Whenever a situation involving SimOps is identified, it is important that all relevant and involved parties come together in order to develop an appropriate hazard and risk management plan.
A useful guide to SimOps planning has been developed by our good friends at IMCA and it is available by clicking here.

SIMOP's oerations are more important, when construction work is carried out in live plant, as Plant modification, production debottlenecking activity, or in other words "Brownfield rifenry construction work", where the Petrochemical Plant operation / Production
activity is in full swing, and construction work is going on for debottlnecking job. Criteria is in live plant flamabiltity of Hydrocarbon process industry is very critical factor, considering woking in Plants having hazardous area classification, Zone 0 or,
Div 01 Plant area, as ISBL (Inside Battery limit Area) of production facililty.
