Abstract

L’invention concerne un système de stabilisation et de sécurité (1) pour un récipient de transport de liquide (2), un récipient intérieur (5) étant agencé à l’intérieur d’un récipient de transport de liquide extérieur (2), formant ainsi un espace intermédiaire (9). Le récipient de transport de liquide peut être en particulier un récipient de véhicule-citerne. Chacun des deux récipients présente au moins un raccord (3, 6) menant vers l’environnement extérieur. Les deux récipients (2, 5) communiquent l’un avec l’autre à travers l’espace intermédiaire (9) par l’intermédiaire d’au moins une ouverture (8), et un gaz sous pression est introduit par l’intermédiaire de l’un des raccords (3, 6) menant vers l’environnement extérieur lorsque le récipient extérieur (2) et le récipient intérieur (5) ne sont pas entièrement remplis, ledit gaz sous pression permettant de pousser le liquide d’un espace (9,10) à l’autre (10, 9) ou de transporter le liquide au moyen d’une pompe d’un espace (9, 10) à l’autre (10, 9), de telle sorte qu’une partie de récipient soit autant que possible remplie entièrement et ainsi stabilisée. Le liquide déplacé est ainsi maintenu dans l’espace souhaité par l’intermédiaire de l’ouverture (8) de raccordement communicante. L’espace libre est par conséquent réduit, (c’est-à-dire qu’il y a moins de liquide en mouvement libre), ce qui évite dans une large mesure une oscillation ascendante du liquide en cas de sollicitations dynamiques, pendant le processus de transport.
