I was wondering, what are the advantages of using Sub sea buoyancy foam for buoyancy? What are alternative cheaper methods for buoyancy?
The subsea buoyancy foam that we offer is designed not to absorb water, even at relatively high pressures. We’ve tested a lot of other foams and almost all of them absorb a significant amount of water under pressure, which means that they get heavier and you lose buoyancy.
If you’re not going too deep, like 10-20m, then there may be other options that would work.
If you’re going much deeper, like 300+ meters, then our foam will start to absorb water and you’d have to look at higher performance alternatives like syntactic foam.
