I somehow doubt this is going to be a floating data center. There are a huge number of problems with such a system.
If you’re using wave generation for power, then they need to be anchored pretty far offshore and you need a lot of them for the power draw of both pumping seawater for cooling and running machines.
You need to haul the whole ship out of the sea at least once every 4 years to do maintenance on the hull which is probably a good thing because a barge this low + sea spray + not-quite-airtight shipping containers means accelerated corrosion plus mold and fungus.
Then there is the small problem of internet access on a bobbing boat. You can have a microwave link as long as you don’t go much beyond 3 miles for gigabit speeds, but you’ll need some exceptionally good stabilizers on the marine side and even then, you’re pretty much limited to ~6 Gbps per tower and I’m not even sure if the FCC allows non-fixed antennas for most of the really high bandwidth frequencies like the e-band.
Then again, Google does buy so many machines that they can afford to have a data center randomly go offline.
