What innovations and concepts can take offshore wind power to much larger scales quickly?

Compared with their onshore counterparts, offshore wind turbines can provide much higher electricity output per turbine owing to higher capacities (up to 10 MW per turbine) and higher capacity utilization (up 50%). But there are significant challenges that offshore wind farms face, both in terms of operations and higher costs. What are the innovations and solutions that can make offshore wind turbines easier to install and operate?
