That concept for an intermediate platform to support far offshore platforms from japan, as a heliport base and PSV base. This design seems to be a turreted platform with a rear submerged dock

MarineBiomass – The official home of Marine Bio Energy
Uh using variable depth buoy/submarine setups seems a bit overkill, could achieve most of the same result with a long pipe for a local deep ocean upwelling to bring the necessary nutrients to the surface. But open ocean kelp farming is an interesting concept itself.

Called Heliofloat, it sounds like a variation of a classical PSP platform, using semi-flexible barrel/cylinder side walls to absorb some wave motion. Using a marine concrete PSP sounds more durable, though at greater weight/cost?

KTH | Making waves with new gear technology
The cascade gear drivetrain that converts linear to rotary movement is kinda interesting. Though for a point absorber, it's probably the difference between a hydraulic pump's valving breaking, and this one grinding it's pinion gear teeth.

NOTRE PROJET
Interesting use of a linear piston motion of a wave power buoy to drive a mechanically driven high pressure seawater pump for a reverse osmosis water desalination rig. RO requires high pressure, which typically requires a lot of electric power for a electric pump, but by using gradual pressure building using a wave driven seawater pump, you can achieve equivalent pressures. Potentially convenient for small island resorts that have very little electrical power. But the long water pipe is a bit of a problem. If it were me, I would use the wave buoy to send pressurized seawaater directly via pipe to a beach building with the RO rig and a pressure accumulator tank, since that keeps the more finicky parts out of the water.
