Abstract
This naval platform (14) supporting a wind turbine (12) for offshore electrical energy production comprises a main support column (24) of said wind turbine (12), and two secondary columns (26); each column including at least one shell having an outer surface delimiting an outer volume; the main column (24) being coupled to the two secondary columns (26). The outer volume delimited by the shell (28A) of the main column (24) is greater than the respective outer volumes delimited by an outer surface of the shell (28B, 28C) of each secondary column (26).
Claims17
A naval platform supporting a wind turbine for offshore electrical energy production, comprising:
- a main support column of said wind turbine;
- and
- two secondary columns,
- each of the two secondary columns comprising at least one shell having an outer surface delimiting an outer volume, and
- the main support column being coupled to the two secondary columns,
- wherein an outer volume delimited by a shell of the main support column is at least 20% greater than respective outer volumes delimited by an outer surface of the shell of each secondary column.
A naval platform supporting a wind turbine for offshore electrical energy production, comprising:
- a main support column of said wind turbine;
- and
- two secondary columns,
- each of the two secondary columns comprising at least one shell having an outer surface delimiting an outer volume, and
- the main support column being coupled to the two secondary columns,
- wherein the outer volume delimited by the shell of the main support column is greater than the respective outer volumes delimited by an outer surface of the shell of each secondary column, and
- wherein a cross-section of the shell of the main support column has a geometric shape different from a cross-section of the shell of at least one of the two secondary columns, and/or the shell of the main support column has a height greater than the height of the shell of each secondary column, and/or the outer volume delimited by the shell of each of the columns is at least greater than 1500 m3.
A naval platform supporting a wind turbine for offshore electrical energy production, comprising:
- a main support column of said wind turbine;
- and
- two secondary columns,
- each of the two secondary columns comprising at least one shell having an outer surface delimiting an outer volume, and
- the main support column being coupled to the two secondary columns,
- wherein the outer volume delimited by the shell of the main support column is greater than the respective outer volumes delimited by an outer surface of the shell of each secondary column, and
- wherein the shell of at least one of the two secondary columns has a rectangular cross-section, a larger axis of the rectangular shape defining an offset angle with a reference line,
- the reference line being defined as passing through the geometric center of the cross-section of the shell of the main support column and as being perpendicular to another line passing through the geometric centers of the cross-sections of the shells of the two secondary columns, and
- the offset angle being comprised between 0° and 90°.
