Abstract: Disclosed is a pontoon (111) for transporting and placing a one-piece marine wind turbine (115) on the seabed, wherein the one-piece wind turbine (115) comprises a base caisson (116) that can be fitted inside the open space of the U-shaped pontoon (111) for transporting, positioning and placing the base caisson (116) of the marine wind turbine (115) on the seabed, by ballasting the base caisson (116) and the U-shaped pontoon (111) in a synchronised manner using seawater.

Abstract: A foundation device for a wind turbine tower includes a hollow main body with a lower face and an upper face. Both the lower face and the upper face contain a hollow space. Each of the faces include an outer perimeter and an inner perimeter. The main body additionally includes an outer lateral wall disposed between the outer perimeter of the lower face and the outer perimeter of the upper face, and an inner lateral wall between the inner perimeter of the lower face and the inner perimeter of the upper face. The device further includes a plurality of columns that project from the upper face of the main body.

Abstract: The invention allows setting up floating platforms comprising an elongated central body (1) from the lower portion of which legs (2) come out intended to fix the platform to anchoring elements arranged in the sea bed (5). The vessel comprises: a) a longitudinal through groove (4) up to the vessel bottom, and leaving part of the vessel bow (5) open; and b) a plurality of slots (6, 7) placed at the bottom of the vessel, wherein the groove (4) and the slots (6, 7) are configured both in dimension and in shape in such a way that they fit in at least some of the legs (2), so that the legs (2) can be inserted, at least partially, in the slots (6, 7) to attach the platform to the vessel.

Abstract: The invention shows improved operational conditions. It comprises a floating structure with a single floating central body (1), provided with an elongated configuration according to a longitudinal direction, wherein the lower portion of the central body (1) is intended to be submerged. It additionally comprises: a base (3) located in the upper portion of the central body (1) to support at least one wind turbine (4); and at least four legs (2) located in the lower portion of the central body (1) and provided with: a) a first end, by which they are integrally attached to the central body (1); b) a second end, opposite to the first end, and more distant from the central body (1); and c) at least a porch (6) located in the second end of each leg (2), said porch (6) comprising a first drilling (12) in longitudinal direction to anchor the floating platform to the sea bed (5).
