Abstract
Structure pour pipelines (2) situés en eaux profondes, selon laquelle un pipeline (6) à paroi interne épaisse comporte une couche enveloppe externe qui confère de la flottabilité et / ou une isolation auxdits pipelines (2). Cette couche enveloppe comporte du béton léger formant ainsi une couche enveloppe de béton léger (5). La couche enveloppe de béton léger (5) est couverte par un tube ou une gaine externe mince (7) qui renforce la couche enveloppe de béton léger (5) et maintient sèche ladite couche (5).
