Abstract

Cette présente invention concerne une structure flottante de conception très légère et très stable destinées à supporter des éoliennes offshore (1) ou tout autre équipement, remorquable en position verticale depuis leur site de fabrication jusqu'à leur site de fonctionnement en mer profonde avec tout leur équipement en tête et, ceci, grâce à son faible tirant d'eau, se libérant ainsi de tout moyens de manutention lourds et onéreux en mer ouverte. Cette structure est caractérisée par le fait que le flotteur (2): - en version émergée, fig.1, permet le remorquage en position verticale de son site de fabrication à son site définitif avec tout son équipement prêt à fonctionner, la stabilité étant assurée par un lest permanent (4) situé sous le flotteur par l'intermédiaire d'une colonne balastable (3). - en version immergée, fig.1 bis, par ballastage (5) de la colonne et d'une partie du flotteur (6) par des pompes (7) situées dans la partie vide du flotteur, permet de donner à l'ensemble une bonne stabilité et d'assurer à l'éolienne de fonctionner dans des conditions de mer fixées par le cahier des charges de l'exploitant. - En version immergée fig. 2bis, le lest étant descendu plus profondément au moyen d'un système à coulisse actionné par un mécanisme soit à crémaillère soit par frein pneumatique ou hydraulique ou partreuils ou autre mécanisme adapté, permet d'améliorer la stabilité dans des conditions de mer plus sévères.This present invention relates to a floating structure of very light and very stable design intended to support offshore wind turbines (1) or any other equipment, towable in a vertical position from their manufacturing site to their operating site in deep sea with all their equipment. equipment at the head and, this, thanks to its shallow draft, thus freeing itself from any heavy and expensive handling means in the open sea. This structure is characterized by the fact that the float (2): - in the emerged version, fig. 1, allows towing in a vertical position from its manufacturing site to its final site with all its equipment ready to operate, stability being ensured by a permanent ballast (4) located under the float via a balastable column (3). - in the submerged version, fig. 1 bis, by ballasting (5) of the column and part of the float (6) by pumps (7) located in the empty part of the float, gives the assembly a good stability and ensure that the wind turbine operates in sea conditions set by the operator's specifications. - In submerged version fig. 2a, the ballast being lowered more deeply by means of a sliding system actuated by a mechanism either with rack or by pneumatic or hydraulic brake or by winches or other adapted mechanism, makes it possible to improve the stability in more severe sea conditions.
