Foam Block
Foam Block
(OP)
Hi All,
I am designing a subsea equipment, which will be using a foam block to make the equipment neutrally buoyant. While we can calculate the buoyant force needed to make the equipment neutrally buoyant in seawater, I have another question.
Suppose the equipment is neutrally buoyant in water at a depth or 100m. But when the equipment goes to a depth of 3000 m, there will be pressure of 3000m of the sea above acting on the equipment. What calculations do I have to confirm that I measure the correct volume of Foam Block for that kind of depth? Thanks in advance.
Regards,
HD

RE: Foam Block
One material commonly used for buoyancy subsea is Syntactic.
I think I would contact a supplier like Balmoral. See the link below. They have tables published for their products which might help you. For example, buoy MCMB1 has a buoyancy of 77kg at the surface, reducing to 28kg at 2000m

You are judged not by what you know, but by what you can do.
