Title
(EN) BUOYANCY DEVICE
(FR) DISPOSITIF DE FLOTTAISON
Abstract
(EN)
With reference to Figure 3 of the drawings, there is shown a vessel (10) including a buoyancy device (20), the buoyancy device (20) extending downwardly away from a hull of the vessel and including a ballast chamber for holding gas and liquid, means for adjusting the ratio of gas and liquid in the chamber, and a connection means (26) connecting the buoyancy device (20) and the hull of the vessel (10), wherein the ballast chamber is moveable relative to the hull of the vessel (10) for adjusting a distance therebetween.
(FR)
Selon l'invention, si l'on se réfère à la Figure 3 des dessins, il est représenté un navire (10) comprenant un dispositif de flottaison (20), lequel dispositif de flottaison (20) s'étend vers le bas de façon à s'éloigner à partir d'une coque du navire, et comprend une chambre de ballast pour contenir un gaz et un liquide, des moyens pour ajuster le rapport de gaz et de liquide dans la chambre, et un moyen de liaison (26) reliant le dispositif de flottaison (20) et la coque du navire (10), la chambre de ballast pouvant se déplacer par rapport à la coque du navire (10) pour ajuster une distance entre celles-ci.
