The most difficult aspect of a big oil and gas project (EPC environment) is the planning of spools. A serial set of spool (a pipe line) is so easy to fabricate and install. A few hundred is still manageable, that means you can still plan it in sequencial order without so much time spent and so many people involved. But when it comes to thousands of spool to be fabricated and installed and is happening at the same time, things will turn out to be complicated. Planning spools will no longer be sequential but unsystematic or randomly erected. This is the reason why welders, pipe fitters, etc. are laughing at planners because after submitting to planners what are the next spools they need to install.they believe it is they who are actually doing the planning job, These same kind of thing is happening even in most respected and biggest company until one planner I know who can single handedly manage to make a truly sequential order of fabrication, QC exam, painting and installation. This what I want to show to companies in the oil and gas industry. Can you help me?
