Title (EN) CONTROLLING BUOYANCY WHEN TOWING, LOWERING AND RAISING SUBMERGED STRUCTURES
(FR) COMMANDE DE LA FLOTTABILITÉ PENDANT LE REMORQUAGE, L'ABAISSEMENT ET L'ÉLÉVATION DE STRUCTURES IMMERGÉES
Abstract:
(EN) A subsea structure comprises: an elongate articulated buoyancy string comprising a longitudinal series of buoyancy elements; and at least one elongate buoyancy holder that is fixed relative to the structure and is capable of housing the buoyancy string. The buoyancy of the structure may be altered by moving the buoyancy string along a transit path that extends along and within the buoyancy holder and through an end opening of the buoyancy holder. The buoyancy string passes through that end opening on being inserted into or withdrawn from the buoyancy holder.
(FR) Une structure sous-marine comprend : une chaîne allongée d'éléments flottants articulés comprenant une série longitudinale d'éléments flottants ; et au moins un support de flottabilité allongé, qui est fixé par rapport à la structure et est capable de contenir la chaîne d'éléments flottants. On peut modifier la flottabilité de la structure en déplaçant la chaîne d'éléments flottants le long d'un trajet de transit qui s'étend le long du support de flottabilité et à l'intérieur de celui-ci, et à travers une ouverture d'extrémité du support de flottabilité. La chaîne d'éléments flottants passe à travers cette ouverture d'extrémité lorsqu'elle est insérée dans le support de flottabilité ou retirée de celui-ci.
