ABSTRACT:
Control forces for stabilizing semi-submersible platforms are provided outboard the platform columns, at a point approximately where the free surface of the water intersects the columns, without altering the internal arrangements or structure of the platform and employing equipment which develops pressures needed to impose control forces only. In a similar manner, control forces for stabilizing pitch and roll motions in ships and to effectively damp the oscillatory motion of the water level in a "moon pool" are provided.
