Dynamic Ballast Oscillation Stabilization

Design and construct a scale model of a semi-submersible vessel capable of maintaining a stable horizontal platform while subjected to multi-axial wave simulation. You must integrate a passive pendulum or active fluid-transfer ballast system to dampen harmonic resonance induced by rhythmic input at the vessel's natural frequency. Success is measured by minimizing the pitch and roll excursion amplitudes relative to a control hull without damping mechanisms.
