Abstract

L’invention a pour objet un corps flottant présentant une jupe 3 s’étendant vers le bas ce corps flottant étant caractérisé en ce que la jupe est fixée à un niveau supérieure à celui défini par la ligne de flottaison 4 correspondant à une charge de référence du corps flottant de manière à constituer avec la coque un volume qui, au-dessus de la ligne de flottaison, contient de l’air ce volume étant relié à une pompe 6 pour en baisser la pression ou l’augmenter et par conséquent enfoncer la coque plus profondément comme le ferait un remplissage de ballast ou sortir partiellement la coque de l’eau Figure pour l’ abrégé : figure 2The subject of the invention is a floating body having a skirt 3 extending downwards, this floating body being characterized in that the skirt is fixed at a level higher than that defined by the waterline 4 corresponding to a reference load of the floating body so as to form with the hull a volume which, above the waterline, contains air, this volume being connected to a pump 6 to lower the pressure or increase it and consequently push the hull deeper as would a filling of ballast or partially removing the hull from the water Figure for the abstract: figure 2
