The technology, tested off the coast of Orkney, Scotland, uses containerised, non-hazardous, low-density gel that provides “incompressible” buoyancy to raise and lower offshore structures, including wind, wave and tidal turbines.

Pumping small quantities of GLS into or out of the bag enabled the weight to be raised, lowered or even made neutrally buoyant so that it would float underwater.
