FIELD: transportation.
SUBSTANCE: invention relates to underwater movement of cargoes. Method of underwater movement of cargoes by changing buoyancy involves movement of cargo on cargo pontoon automated platform, along alternating ascending and descending sections of transportation route. Platform is equipped with a reservoir with compressed air and elastic bags. Cargo is moved by increasing and decreasing buoyancy. For passage of ascending sections, buoyancy is increased by forcing air into elastic bags. For passage of descending sections of the route, buoyancy is lowered by releasing air from elastic bags.
EFFECT: simplified method of underwater movement of cargoes.
