Abstract

La présente invention se rapporte à une structure marine comprenant : un corps principal conique vide (100) ; une pluralité de colonnes (200) faisant saillie dans une direction verticale depuis une surface intérieure du corps principal (100) ; et une pluralité de parties d'installation de pilier (300) faisant saillie depuis les surfaces extérieures de chaque colonne de la pluralité de colonnes (200) au niveau de l'extrémité inférieure du corps principal (100). Chacune des parties d'installation de pilier comporte, dans son cœur, un trou d'installation de pilier (301). Selon la présente invention, on peut obtenir une stabilité structurale suffisante sans trop d'effort excessif ni coûts de fabrication et de construction excessifs.
