As long as there are failsafe ways up to the surface, ok.
“As long as there are failsafe ways up to the surface”
That is the the kind of thing i was looking for in the article, that I did not see - innovative engineering approaches that are a clear break from the past.
Flotation materials that won’t rot or fail, structures that can inherently endure the worst storms at sea, or new approaches to corrosion resistance.
If it is essentially a just bunch of barges tethered together, a huge ship with propulsion, or structures extended from the side of an oil rig; maintenance costs will be huge.
Nothing at sea is fail safe. Ever.
