Abstract

a invenção se refere a um módulo de flutuabilidade (100, 200, 300, 400, 500, 700) que compreende múltiplos elementos de flutuabilidade (104, 204, 304, 404, 504, 604, 704) acoplados entre si. cada um dentre os elementos de flutuabilidade tem um recesso (110, 210) e os elementos de flutuabilidade são lateralmente justapostos com seus recessos alinhados uns aos outros para cercar o membro alongado em uso. os múltiplos elementos de flutuabilidade são empilhados uns sobre os outros ao longo de uma direção que é axial em relação ao membro alongado em uso, para formar um módulo de flutuabilidade de uma profundidade axial predeterminada. os recessos dos módulos de flutuabilidade juntos formam uma passagem axialmente estendida através da qual o membro alongado passa.The invention relates to a buoyancy module (100, 200, 300, 400, 500, 700) comprising multiple buoyancy elements (104, 204, 304, 404, 504, 604, 704) coupled together. each of the buoyancy elements has a recess (110, 210) and the buoyancy elements are laterally juxtaposed with their recesses aligned with one another to surround the elongate member in use. the multiple buoyancy elements are stacked on each other along a direction that is axial to the elongate member in use to form a buoyancy module of a predetermined axial depth. The recesses of the buoyancy modules together form an axially extended passageway through which the elongate member passes.
