Abstract
Des réalisations de structures à embase-poids sont présentées qui comprennent une première et une deuxième section de base allongées séparées par une région ouverte, et configurées pour soutenir le poids au bas de la structure sur un fond marin et une section supérieure positionnée au-dessus de la région ouverte et configurée pour se prolonger au moins partiellement au-dessus de la surface de l'eau pour soutenir des structures d'installations en surface. Certaines réalisations comprennent également une première et une deuxième section inclinées raccordant les sections de base à la section supérieure. Certaines réalisations comprennent une structure de jupe sous les sections de base pour faciliter l'engagement avec le fond marin et un système de conduits configuré pour conduire le fluide entre les compartiments pour aider à l'établissement de la structure sur un fond marin ou le soulèvement de la structure du fonds marin. Certaines réalisations comprennent des chambres de fluide internes remplissables sélectivement pour faciliter le soulèvement ou l'abaissement de la structure dans une mer et le repositionnement de la structure.
