Title (EN) A BUOYANCY DEVICE
(FR) DISPOSITIF FLOTTANT
Abstract: front page image
(EN)A buoyancy device (200) is described as comprising one or more buoyancy members, such as inflatable bags, diaphragms, bladders or chambers, for attachment to a structure (203) to be floated or sunk such as a drilling rig. In one embodiment, the buoyancy member comprises a restriction device, such as a substantially rigid tubular, and an inflatable member located substantially within the restriction device, such that the restriction device restricts inflation of the inflatable member. In another embodiment, the buoyancy member comprises a substantially flexible portion and one or more end portions, where the end portions may be dome shaped, the or each end portion being releasably attached to the flexible portion.
(FR)Ce dispositif flottant (200) comprend un ou plusieurs éléments flottants, tels que des sacs, diaphragmes, vessies ou chambres flottants, destinés à être attachés à une structure (203) qui doit flotter ou être immergée, telle qu'un appareil de forage. Dans un mode de réalisation, l'élément flottant comporte un dispositif de limitation, tel qu'un élément tubulaire, sensiblement rigide, ainsi qu'un élément gonflable, placé essentiellement dans le dispositif de restriction, de manière que ce dernier limite le gonflage de l'élément gonflable. Dans un autre mode de réalisation, l'élément flottant comprend une portion sensiblement flexible ainsi qu'une ou plusieurs portions d'extrémité, lesquelles peuvent revêtir une forme de dôme, chaque portion d'extrémité étant fixée amovible sur la portion flexible.
