Abstract
Description
FLOTTEUR HYBRIDE D'EOLIENNE OFFSHORE HYBRID FLOAT OF OFFSHORE WIND
La présente invention concerne un flotteur hybride, notamment d'éolienne offshore. The present invention relates to a hybrid float, in particular an offshore wind turbine.
De tels flotteurs sont déjà connus dans l'état de la technique, comme par exemple par le document WO 2014/031009. Such floats are already known in the state of the art, for example by the document WO 2014/031009.
Ce document décrit un tel flotteur qui comporte au moins quatre colonnes par exemple en acier, dont une colonne centrale, et trois colonnes extérieures, raccordées à la colonne centrale par des branches en forme de ponton en béton. This document describes such a float which comprises at least four columns, for example steel, including a central column, and three outer columns, connected to the central column by concrete pontoon-shaped branches.
Dans ce document, les colonnes extérieures sont reliées à la colonne centrale selon une configuration en étoile. In this document, the outer columns are connected to the central column in a star configuration.
Les colonnes extérieures et les branches en forme de ponton de ce flotteur comportent alors également par exemple des ballasts, permettant de régler le niveau de flottabilité de ce flotteur. The outer columns and pontoon-shaped legs of this float then also include for example ballasts, to adjust the buoyancy level of the float.
Ceci permet par exemple le transport et l'installation de cette éolienne sur un site de production d'électricité. This allows for example the transport and installation of this wind turbine on a power generation site.
Les flotteurs de cette nature sont dits hybrides car ils utilisent une structure mixte par exemple en acier pour les colonnes et en béton pour les branches en forme de ponton, entre celles-ci. Floats of this nature are called hybrid because they use a mixed structure for example steel for columns and concrete for pontoon-shaped branches, between them.
Dans le document antérieur mentionné précédemment, des moyens de vidange par pompage de ces ballasts sont également prévus. In the aforementioned earlier document, means for pumping out these ballasts are also provided.
Ces moyens de pompage permettent en effet de pomper de l'eau hors de ces ballasts pour modifier la flottabilité de l'ensemble. These pumping means in fact make it possible to pump water out of these ballasts to modify the buoyancy of the assembly.
Ce document antérieur décrit donc de façon générale le concept de flotteur hybride. This earlier document therefore describes in a general way the concept of hybrid float.
La présente invention a pour but de faire progresser la définition de ce type de flotteurs. The present invention aims to advance the definition of this type of floats.
A cet effet, l'invention a pour objet un flotteur hybride notamment d'éolienne offshore, comportant au moins quatre colonnes, dont une colonne centrale et trois colonnes extérieures raccordées à la colonne centrale par des branches en forme de ponton en béton, caractérisé en ce qu'il comporte, associée à chaque branche en forme de ponton, une couronne d'éléments en saillie de tirants de fixation de la colonne correspondante. For this purpose, the subject of the invention is a hybrid float, in particular an offshore wind turbine, comprising at least four columns, including a central column and three external columns connected to the central column by concrete pontoon-shaped branches, characterized in that what it comprises, associated with each branch-shaped pontoon, a ring of elements projecting tie rods of the corresponding column.
Suivant d'autres caractéristiques du flotteur selon l'invention, prises seules ou en combinaison : - les tirants de fixation sont noyés dans le béton des branches en forme de ponton ; According to other features of the float according to the invention, taken alone or in combination: - the tie rods are embedded in the concrete pontoon-shaped branches;
- les tirants de fixation sont disposés sous la forme d'une cage d'ancrage noyée dans le béton des branches en forme de ponton ; - The tie rods are arranged in the form of an anchor cage embedded in the concrete pontoon-shaped branches;
- les éléments de fixation sont adaptés pour s'étendre dans des trous de moyens en forme de bride de fixation de la colonne ; the fastening elements are adapted to extend in holes of means in the form of a fastening flange of the column;
- les éléments de fixation sont adaptés pour coopérer avec des moyens de serrage en position de la colonne sur la branche en forme de ponton ; - les moyens de serrage comportent des écrous adaptés pour coopérer avec des portions d'extrémité filetées des tirants; - The fasteners are adapted to cooperate with clamping means in position of the column on the pontoon-shaped branch; - The clamping means comprise nuts adapted to cooperate with threaded end portions of the tie rods;
- une couche de mortier d'assise est interposée entre les branches en forme de ponton et les moyens en forme de bride. - A layer of bedding mortar is interposed between the pontoon-shaped legs and the flange-shaped means.
L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels : The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawings, in which:
- la figure 1 représente une vue en perspective d'un exemple de réalisation d'un flotteur hybride d'éolienne offshore selon l'invention ; FIG. 1 represents a perspective view of an exemplary embodiment of a hybrid offshore wind turbine float according to the invention;
- la figure 2 illustre les différentes parties de ce flotteur ; et FIG. 2 illustrates the different parts of this float; and
- les figures 3 et 4 représentent différentes vues en coupe et/ou avec des portions arrachées et en transparence illustrant la fixation d'une colonne sur une branche de ce flotteur. - Figures 3 and 4 show different views in section and / or with torn portions and transparency illustrating the attachment of a column on a branch of the float.
On a en effet illustré sur les figures 1 et 2, un flotteur hybride notamment d'éolienne offshore. Indeed, FIGS. 1 and 2 show a hybrid float, in particular an offshore wind turbine.
Cette éolienne offshore est désignée par la référence générale 1 sur ces figures, et le flotteur de celle-ci est désigné par la référence générale 2. This offshore wind turbine is designated by the general reference 1 in these figures, and the float thereof is designated by the general reference 2.
Dans la présente demande, le terme « hybride » est utilisé pour décrire un flotteur utilisant deux matériaux différents pour réaliser des parties de celle-ci. In this application, the term "hybrid" is used to describe a float using two different materials to make parts thereof.
Ainsi et comme cela a été indiqué dans le document antérieur mentionné précédemment, un tel flotteur 2 comporte par exemple au moins quatre colonnes par exemple en acier, dont une colonne centrale, désignée par la référence générale 3, et trois colonnes extérieures désignées par les références 4, 5 et 6. Thus, and as indicated in the prior document mentioned above, such a float 2 comprises for example at least four columns, for example steel, including a central column, designated by the general reference 3, and three outer columns designated by the references 4, 5 and 6.
Ces colonnes extérieures sont raccordées à la colonne centrale, par des branches en forme de ponton en béton, dont deux, par exemple 7 et 8, sont illustrées plus clairement sur les figures 1 et 2. Bien entendu, d'autres matériaux comme par exemple des matériaux composites peuvent être utilisés. These outer columns are connected to the central column by concrete pontoon-shaped branches, two of which, for example 7 and 8, are illustrated more clearly in FIGS. 1 and 2. Of course, other materials such as composite materials can be used.
Comme cela a été indiqué précédemment également, la colonne centrale et les colonnes extérieures peuvent être des colonnes par exemple en acier ou autre et présenter une section cylindrique, tandis que les branches en forme de ponton peuvent être réalisées en béton et présenter une section polygonale comme par exemple rectangulaire ou carrée. As previously indicated also, the central column and the outer columns may be columns for example steel or other and have a cylindrical section, while the pontoon-shaped branches may be made of concrete and have a polygonal section as for example rectangular or square.
De façon classique également, dans ce type de flotteur, les colonnes extérieures et les branches en forme de ponton comportent des ballasts. Also conventionally, in this type of float, the outer columns and the pontoon-shaped branches comprise ballasts.
On voit également apparaître sur ces figures, la différence de nature de matériau de réalisation de ces éléments à savoir les colonnes par exemple en acier ou autre et les branches en forme de ponton en béton. We also see appear in these figures, the difference in kind of material of realization of these elements namely the columns for example steel or other and concrete pontoon-shaped branches.
Pour assurer la liaison entre les colonnes et les branches en forme de ponton, on utilise des couronnes d'éléments en saillie de tirants de fixation de la colonne correspondante. To ensure the connection between the columns and the pontoon-shaped branches, use is made of crowns of elements projecting from fastening rods of the corresponding column.
En effet, et comme cela est illustré sur les figures 3 et 4, des tirants de fixation, comme par exemple le tirant 9 illustré sur ces figures, sont noyés dans le béton des branches en forme de ponton et leur extrémité supérieure fait saillie au-dessus de la branche. Indeed, and as is illustrated in Figures 3 and 4, tie rods, such as the tie rod 9 illustrated in these figures, are embedded in the concrete pontoon-shaped branches and their upper end protrudes beyond- above the branch.
En fait, ces tirants de fixation par exemple 9, sont disposés sous la forme d'une cage d'ancrage noyée dans le béton des branches en forme de ponton. In fact, these tie rods for example 9, are arranged in the form of an anchoring cage embedded in the concrete pontoon-shaped branches.
Cette cage comporte par exemple une bride d'ancrage inférieure désignée par exemple par la référence générale 10 sur la figure 3. This cage comprises for example a lower anchoring flange designated for example by the general reference 10 in FIG.
Un ferraillage quelconque, désigné par la référence générale 1 1 , peut également être utilisé de même que des câbles de précontrainte désignés par les références 12 et 13 sur cette figure 3. Any reinforcement, designated by the general reference January 1, can also be used as well as prestressing cables designated by the references 12 and 13 in this Figure 3.
Comme cela a été indiqué précédemment, l'extrémité supérieure filetée de chaque tirant comme par exemple le tirant 9, fait alors saillie au-dessus de la branche en forme de ponton par exemple 8, afin de permettre de fixer la colonne correspondante par exemple 2. As indicated above, the threaded upper end of each tie such as for example the tie rod 9, then projects above the pontoon-shaped branch for example 8, to allow the corresponding column to be fixed, for example 2 .
En fait, ces éléments de fixation sont alors adaptés pour s'étendre dans des trous de moyen en forme de bride de fixation de la colonne, comme par exemple la bride désignée par la référence générale 14 sur les figures 3 et 4, pour la colonne correspondante 5. In fact, these fastening elements are then adapted to extend into holes in the form of fixing flange of the column, for example the flange designated by the general reference 14 in FIGS. 3 and 4, for the column corresponding 5.
Des moyens de serrage en position de cette bride et donc de la colonne correspondante sur la branche en forme de ponton sont alors utilisés. Ces moyens de serrage sont désignés par la référence générale 15 sur ces figures 3 et 4, et sont par exemple formés par des écrous et des rondelles d'appui, adaptés pour coopérer avec les extrémités filetées correspondantes des tirants, afin d'assurer la fixation de la colonne sur le reste de la branche. Clamping means in position of this flange and therefore of the corresponding column on the pontoon-shaped branch are then used. These clamping means are designated by the general reference 15 in these Figures 3 and 4, and are for example formed by nuts and bearing washers, adapted to cooperate with the corresponding threaded ends of the tie rods, to ensure the attachment of the column on the rest of the branch.
Bien entendu d'autres moyens de serrage peuvent être utilisés. Of course other clamping means can be used.
On notera également qu'une couche de mortier d'assise, désignée par la référence générale 16 sur ces figures 3 et 4, peut être utilisée pour améliorer encore cette fixation. It will also be appreciated that a layer of bedding mortar, designated by general reference 16 in these Figures 3 and 4, may be used to further enhance this attachment.
On notera bien entendu que d'autres modes de réalisation de ces différents moyens peuvent être envisagés. Of course, other embodiments of these different means can be envisaged.
