Semi diving floater, especially semi diving floater for floating wind turbine

摘要

The present invention defines an operating state and a non operating state, and at least two outer columns (24), a central column (22) for receiving a payload, and an outer column for each outer column (24) are connected to a central column The present invention relates to a semi submerged floater (12) including a branch portion of a pontoon (30) defining a branch shaft (a) directed from the center column (22) to the outer column (24).Each branch portion (30) is formed of a first portion (42) and a second portion (44) extending continuously along a corresponding branch axis (a), and one of them is at least 10% of the total range (E) of the branch part (30) along the branch axis.In the operating state of the floater (12), the second portion (44) of each branch portion (30) is filled with at least a ballast material (66) and the first portion (42) does not contain any ballast material.
