A method of installing an object under water at a desired location, the method comprising: providing the object on a vessel, connecting the object to a submersible frame located below the water surface, wherein the vessel is spatially separated from the submersible frame along the direction of the water surface, releasing the object from the vessel such that the object becomes submerged and carries out a pendulum motion until the object is suspended from the submersible frame, and moving the object to the desired location. La présente invention concerne un procédé d'installation d'un objet sous l'eau à un emplacement souhaité, le procédé consistant : à disposer l'objet sur un vaisseau, à relier l'objet à une structure submersible située en dessous de la surface de l'eau, le vaisseau étant spatialement séparé de la structure submersible dans la direction de la surface de l'eau, à libérer l'objet du vaisseau de telle sorte que l'objet soit submergé et effectue un mouvement de pendule jusqu'à ce que l'objet soit suspendu à la structure submersible, et à déplacer l'objet jusqu'à l'emplacement souhaité.
