Well, so far you haven’t really convinced me your costs would be that much more. Start there and you may make some headway.
If you believe oil/gas companies are not interested in making more money, and don't look at cash flow for projects costing billions of dollars, I don't think you are going to be convinced by me.
I once worked a oil field production facility where every barrel of oil had a 40% split with the foreign government for oil produced after January 1, 1994. Any barrel produced before that had 0% government take. We designed for 120,000 barrels per day. We started flowing months early, although not at full flow.
I've been part of emergency rebuilds where not only the construction but the engineering and design work 24/7 for half a year. If you think I don't understand rush projects, you are mistaken.
Have a great day, God Bless.
