I'd expect a stationary submarine to be much more suceptible to rolling? A raised tower or other non-symmetrical features might also cause a bobbing motion in the roll.
I'd also expect the submarine to have to adjust its ballast tanks in order to maintain a level buoyancy.
When a submarine is moving at cruise speed these things can easily be compensated for by the fins and rudders, but the motors will neccesarily make noise. Heck, even moving through the water (instead of floating with the current) may create undesirable artifacts.
- cr1895 9y agoYeah could be prone to high roll motion depending on the heading relative to the predominant waves. I'm guessing though that for whatever scientific purposes it would be submerged and not rolling/pitching at all.
- amelius 9y agoIn that case wouldn't a set of gyroscopes and/or gimbal solve the problem in a cheaper way?
- cr1895 9y agoSolve what problem? If you make something gimbaled on a ship (pool table, for instance) you can prevent rotation, but not translation...at least not without some complicated active motion compensation system.
