Definition

Stability is a kind of ability to enable an AUV/ROV/HOV to restore the original position after deviating from the equilibrium position under disturbing force. The distance, BG, between the center of gravity (G) and the center of buoyancy (B), governs the stability characteristics of the submerged submersible. For a surfaced boat, the measure of the stability is given by the distance GM (metacentric height). Thus, to be in stable equilibrium when the surfaced boat upright, the vertical position of the center of gravity (G) should be sufficiently below that of the center of buoyancy (B) or metacenter (M).

Scientific Fundamentals

For the submerged AUV/ROV/HOV, only intact stability needs to be considered because there is no reserve of buoyancy. Hydrostatic stability, both transverse and longitudinal, i.e., in heel and...
