I was wondering, what are the advantages of using Sub sea buoyancy foam for buoyancy? What are alternative cheaper methods for buoyancy?
Hi @NIW,
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.
