structure-fluid interaction

Dear all

I'd like to model a floating object with mooring lines objected to wave which contains a pneumatic chamber that water can rise and fall in it. So I face with 3 phases( rigid body, water, air).Also, the body moves because of the wave impact.

I want to understand the hydrodynamic behavior (diffraction and radiation). I know that there are solvers in openFoam extended for fluid structure interaction.

Which solvers are suitable for me and what's their method for solving?
I know that Boundary Element Method can do this work well. Is it contained it openFoam?

If an image is needed I can put it here.
I appreciate any help.

By the way, can anyone explain about fluid-structure interaction (like fsiFoam, icoStructFoam)?
which numerical methods do they use and what's the theory behind them? Do they contain dynamic mesh or not?

Regards,
