A method for lifting a sea platform or like construction from the substructure, wherein use is made of at least one flotation body, wherein - the flotation body is fixed to a part of the substructure, - the flotation body is given a buoyancy by removing part of the water, - a separation is made in the substructure below the connection point between flotation body and substructure, - the buoyancy of the flotation body is increased by removing more water, and - the or each flotation body with platform part fixed thereto is moved to an end location.

La présente invention vise une méthode permettant de soulever une plate-forme marine ou autre construction semblable montée sur une infrastructure, où au moins un élément flottant fixé à une partie de l'infrastructure est utilisé, la flottabilité de cet élément flottant étant assurée par l'évacuation d'une partie de l'eau qu'il contient. La séparation est effectuée sous le point de raccordement de l'élément flottant et de l'infrastructure, la flottabilité de l'élément flottant étant augmentée par le retrait d'une quantité supplémentaire d'eau, et l'élément flottant ou chacun des éléments flottants assujettis à une partie de la plate-forme est déplacé vers sa destination finale.
