A wind turbine offshore installation method of installing a wind turbine using a semi-submersible type floating substructure includes: a step of towing the semi-submersible type floating substructure on which the wind turbine is erected to an installation target site on a sea; and a step of coupling the wind turbine and a spar type floating substructure for supporting the wind turbine on the sea at the installation target site to install the wind turbine on the sea.

The invention relates to a structure (2) for supporting a wind turbine tower (1) provided with a housing (7) for fitting therein the foot of the tower (1), a main axis (Γ) being defined on the platform (2) which coincides with a main axis of the tower (1), and which comprises a body with a constant cross-section and internal walls (8) and intermediate walls (10) joined by internal radial ribs (11) perpendicular to the internal wall (8) whose plane passes through the main axis (Γ), such that at the intermediate wall (10) first joining nodes (12) are defined between the intermediate wall (10) and radial ribs (11), the intermediate wall (10) and an external wall (9) being joined by reticular ribs (14 and 15). This structure provides an optimal transmission of forces. The invention likewise relates to methods for manufacturing, assembling and installing the structure.

A drill device comprising: a pile configured such that same descends to a seafloor surface through a mooring installation device provided in a ship, and a part of the body thereof is fixed in an area of the seafloor surface as the upper surface thereof is pressurized in the vertical direction; a driving pipe configured such that same descends to the seafloor surface through a through-hole formed in the pile, the body thereof is inserted into a seafloor foundation, and same is recovered through the through-hole after excavation is completed; a chain, one end of which is fixed to one side of the pile, and the other end of which is introduced through the through-hole such that same is inserted into the seafloor foundation together with the driving pipe; and a drill bit unit.

A method for constructing a wind turbine concrete floater including a central connector from which radial arms extend, the central connector carrying a central stability tower, and each arm carrying an outer stability tower. The method includes prefabricating the arms, central connector and at least parts of the stability towers, pre-assembling the central connector with one arm to form a primary pre-assembly, mounting temporary flotation devices onto the arms to provide additional buoyancy to them, floating the primary preassembly and floating the other arms of the floater, and assembling offshore said primary preassembly with said other arms.

A method of transporting a first vessel having wind turbine components to an offshore installation vessel. The method includes (i) securing the first vessel to a second vessel using a first tow line attached to a front end (or bow) of the first vessel, and (ii) securing the first vessel to a third vessel using a second tow line attached to a back end (or stern) of the first vessel. The method further includes transporting the first vessel to the offshore installation vessel using the second vessel and the third vessel secured to the first vessel via the first and second tow lines, respectively. The method also includes securing the first vessel to the offshore installation vessel. The first vessel can include one or more fender walls. The first vessel can be secured to the offshore installation vessel using one or more mooring lines.
