Most oil producing nations are both exporters and importers of crude oil and products, hence the term "net exporter" to define countries that is self-sufficient oil producers.
Indonesia is importing much of it's crude from Saudi Arabia and products from Singapore, although it is a major exporter of crude oil and LNG. (No longer "net exporter" though)
Nice thought, but were is the American capacity to do so?
- Your deepwater rigs are foreign flag, foreign built and fitted with foreign made machinery and equipment. There is no American yards building such rigs, or making the machinery and equipment required. (NOV make their high end drilling equipment and cranes in Norway)
- The Spar platforms are built in Finland and transported to USA on Dutch HLV, with much of the deck modules manufacture abroad, for assembly at Ingleside.
-There are no US-flag SSCVs to do the installation, or heavy Pipelayers to lay pipes in deep water, nor is any likely to be built in USA.
In stead of trying to build up a fleet of inefficient vessels that will not be able to compete outside GoM, you are better off concentrating on what you CAN do and get foreigners to do the rest with already existing equipment.
Aren't many of the "multi-national Oil companies" of American origin and working worldwide, with little or no consideration to local "sensitivity", where they can get away with it?
I realize that Oil Companies of foreign origin is operating in the GoM, many of them wholly or partly state owned. (Statoil, Petrobras, ENI, CNOOC etc.) But aren't they operating through US subsidiaries, paying taxes in the US and employing thousands of US citizens?
The taxation bit would only work if there were a shortage of oil and places to explore in the world. Do you believe that ExxonMobil, Chevron et al. would drill in the GoM if they could not make a profit? They would high tail it to more friendly environ faster then you could say "national duty". (Russian Arctic maybe??)
Like I said, pipe dreams and "alternativ facts" are for Trumpists, not for realistic thinking Mariner that can see the real world.
