The invention relates to a maritime structure for laying the foundations of buildings, installations or wind turbines by means of gravity in a marine environment, which has significant advantages for constructing, transporting, positioning and operating same, owing to the novel features introduced into the design thereof in comparison with existing types. The structure comprises a base in the shape of a chamfered equilateral triangle, having a sufficient height to optimise navigability, the base being formed by a frame of vertical walls that form hexagonal or triangular cells closed at the ends by a lower slab and an upper slab, and three closed towers having a regular hexagonal or circular cross section which are located in the corners of the base. The structure can be towed, completely installed, with a wind turbine or superstructure that same supports, and has low initial draft, high naval stability and low resistance to movement. The lowering process is performed by using gravity to ballast the cells with seawater, without needing any additional means, auxiliary large-capacity vessels or floating elements external to the structure itself. The structure can be positioned as a gravity foundation at a depth of 20 to 50 meters and can be re-floated to be transferred whole again to a port for dismantling.
A maritime structure for laying foundations of buildings, installations or wind turbines by means of gravity in a marine environment, characterised in that it is made up of a base and three towers, wherein the base is a prismatic concrete structure with a triangular base, truncated at the corners thereof, and is made up of vertical outer walls and an inner frame of vertical walls that form hexagonal or triangular cells, fillable with seawater and which close at ends thereof by a lower slab and an upper slab defining a support for the three towers, wherein the three towers are situated in correspondence with three corners of the base, wherein outer walls of the three towers are vertical extensions of walls in corresponding corners of the base, the three towers incorporating inner chambers fillable with ballasting seawater, the towers situated at the corners having a regular hexagonal or circular cross section and being closed at an upper part thereof by a small slab that forms a cover.
