The article talks about how oil service crane ships are designed for heavy, not high. There are prototype crane ships for the task, but they cost $250 million minimum which hampers growth of offshore wind installation. The issue is the blade length and positional stability, so sinking isn’t much of a solution. My takeaway is that this is promising but a few engineering feats from being economically sensible.
