It's basically a fiberglass tube. Corrosion from a quick dunk is a trivially solve-able issue since everything that could corrode will already need to be protected enough fora decades long service life in salt spray. I can't see sinking it for routine maintenance being cost effective. Even at a hundreds of dollars per man hour it's still probably not gonna be cheaper than making the maintenance people climb a ladder.
That said, being able to lay over the main tube at like 60deg would make it way easier to construct them since you could use a much smaller and cheaper crane to assemble and it would minimize the side to side movement caused by rolling. You basically just need a cleverly engineered chamber to pull that off since the ship can have all the pumping hardware.

The companies can built them so high because they gave up the idea that the tower can withstand any wind thrown at it and still oppose the wind enough to produce energy. Instead, smart computer programs turn the propeller angles independently, so that when the blade reaches the top (where it exerts maximum torque trying to topple the tower), it is angled such that it won't catch too much wind. Then when the blade is near the bottom, it's turned again in order to capture most wind.
