ABSTRACT:
A passive near neutral buoyancy platform includes a structure housing a series of gas-filled cells, restrained in their maximum volume regardless of the internal charge pressure, and collapsible in character when external pressure exceeds the charge pressure. With this structure, once a cell having a predetermined initial internal charge pressure reaches a depth where the external pressure exceeds this initial value, that cell contracts, resulting in a net buoyancy change for the structure. Where this series of cells is attached integrally to a single structure, the cells form a pre-loaded compressibility compensation device which is matched to the external environment.
