L’invention concerne un caisson ouvert de type assemblable et une structure de génie maritime, selon lesquels : le caisson ouvert est formé en disposant plusieurs unités principales reliées ; lesdites unités comprennent un pilier enfoncé dans le sol marin et une structure formant caisson située sur le pilier et au-dessus du niveau de l'eau ; un remblai de galets (5) remplit la structure formant caisson. La structure de génie maritime comprend une plate-forme de fondation formée en disposant de manière équidistante plusieurs unités principales reliées, les unités comprenant un pilier enfoncé dans le sol marin et une structure formant caisson située sur le pilier et au-dessus du niveau de l’eau, et un remblai de galets (5) remplissant la structure formant caisson. Les unités se présentent suivant deux types de structures : dans l’une, la liaison est de type pilier-dalle (4), dans l'autre elle est de type dalle-dalle (30).
