And my point is that, given how deep these things seems to be, it is cheaper to haul them on the surface than sending a diver down, even if you need to do some unscheduled maintenance, especially because sending down a commercial diver (the only that can hope to work this deep) is not an easy feat in itself.
Obviously it will be expensive either way, I was only pointing out that sending down commercial divers a lot of additional levels of complexity (decompression periods measured in days or weeks, need to hire many more highly specialized people and from a way smaller pool and so on) that will drive up the price.
Did you not catch the part a couple comments ago where I agreed with you? Yeah, of course it’s cheaper to not send divers down. All I’m saying is cheaper cheaper doesn’t mean cheap. And my larger point is that it’s probably not cheap enough, not least because they’re planning for a 20 year part replacement cycle on metal bits exposed to high-pressure seawater and that just doesn’t seem plausible to me.

Nope, miss it. My bad ;-)

I think that this depends on how much this system can really “produce”.
In a 20 years cycle (ok it is theoretical), it does not seems too hard to overcome the maintenance costs, even this high, assuming the production is high enough, which is to be demostrated.
