Abstract

L'invention concerne une solution technique pour réaliser une liaison d'une structure de fondations avec le fond de la mer ou de l'océan, qui compense les charges générées en mer par l'installation, et le fonctionnement d'une construction en mer en utilisant une combinaison de cuves qui supportent les charges tout en utilisant en même temps l'effet de la pesanteur. L'avantage particulier de l'invention est de pouvoir installer des fondations pour des constructions en mer avec une très faible émission sonore. Elle permet en outre de faire des économies de coût pendant l'installation en mer.
