Abstract

Vaisseau semi-submersible comprenant au moins un élément ou module de forme annulaire constituée d'une enceinte fermée, étanche à lest variable à la partie inférieure, sur laquelle est fixée une structure à claire-voie partiellement immergée et portant à sa partie supérieure un tablier horizontal, suivant la revendication 1 du brevet principal. L'enceinte fermée, étanche 1 est délimitée par des parois extérieure 35 et intérieure 36 en forme de surface courbe, ladite surface intérieure 36 délimitant une cavité concave ouverte à ses deux extrémités. L'invention est utilisée dans les vaisseaux semi-submersibles.
