Abstract

L'invention concerne un procédé d'ajout d'eau au cours d'un allègement de navire : dans l'hypothèse où l'étrave d'un navire n'est pas chargée en eau de ballast, le navire est allégé sur une barge semi-submersible ; la barge semi-submersible est déplacée vers une fosse profonde et le navire est amené à s'immerger à deux profondeurs de calaison jusqu'à ce que la barge semi-submersible soit immergée au point de se séparer du navire ; chaque fois que le navire s'immerge à une profondeur de calaison, une pompe submersible de la barge semi-submersible charge l'eau de ballast d'un volume correspondant à la profondeur de calaison dans un réservoir de ballast au niveau de l'étrave du navire ; et lorsque la barge semi-submersible est immergée au point de se séparer du navire, le navire est remorqué hors de la barge semi-submersible. Lorsque la barge semi-submersible ne peut pas mettre en œuvre un allègement de navire à eau de ballast à pleine capacité, par allègement du navire non chargé en eau de ballast directement sur la barge semi-submersible, alors sous l'action de la barge semi-submersible le navire est amené à s'immerger à une certaine profondeur et le poids du navire est réparti au moyen de la flottabilité de l'eau, de l'eau de ballast est ensuite chargée dans le réservoir de ballast au niveau de l'étrave du navire jusqu'à ce que la barge semi-submersible soit immergée au point de se séparer du navire, et la nécessité de passer à une barge semi-submersible relativement petite lors de la mise à flot du navire est éliminée.
