Abstract
A semi-submersible float has four columns including a central column intended to receive a wind turbine mast, and at least three external columns that are connected to the central column by branches forming lower pontoons. The float is devoid of upper branches connecting the central column to the external columns and the external columns and the lower pontoons are each formed by an assembly of planar panels and each have a polyhedral cross-section. A method is provided for constructing such a float.

A semi-submersible float, in particular for an offshore wind turbine, comprising four columns including a central column intended to receive a wind turbine mast, and at least three external columns that are connected to the central column by branches forming lower pontoons, the float being devoid of upper branches connecting the central column to the external columns and the external columns and the lower pontoons each being formed by an assembly of planar panels and each having a polyhedral cross-section,
- wherein the planar panels forming the external columns are assembled together by at least one rounded rod so as to improve their hydrodynamic behavior and reduce stress concentrations.
