Abstract: Multi-purpose offshore platform and method for manufacturing and installing thereof in the water for the installation of power generation, desalinated water and food production devices from sea's natural resources, or in order to serve as foundation for any structure to be installed in water. It includes a foundation formed by one or more reinforced concrete slabs (1) with lattice (3) pillars, piles for driving into the seabed, placed inside the pillars (3), a superfluous sealing and buoyancy system (8), an immersion controlling system that allows inmersing the foundation at a controlled rate, once the platform is in its final location, a hydraulic system for lifting the platform to a height above the highest wave expected, as well as plants (5) for installing devices.

Abstract: A new system of hydraulic and piston cylinders for the lifting of large loads manufactured based on commercial tubes, in which the cylinder tube (1), closed on its lower part possesses a welded and rigid washer (2) on its lower part and inside the aforementioned cylinder. The piston has another rigid washer welded to it (4) at a certain distance from the lower end and on its outer surface. Between the two there is an O-Ring seal (6) of variable geometry that is constructed with an elastomeric, compressable and deformable material of low friction and high elasticity and a free washer. The compression of the O-Ring seal makes up a system that closes, guaranteeing its watertightness.

Abstract: Superfluous sealing, buoyancy and immersion controlling system for floating appliances having a primary, secondary and tertiary buoyancy systems, a buoyancy system of devices and operation and maintenance plants, a set of submersible pumps, a console for controlling and automating the immersion operations and a set of programmable valves. This superfluous system allows any appliance or platform to be able of easily being towed to its final location at sea, ocean, lake . . . regardless of the size, shape or weight thereof, and weather conditions. Similarly, this system enables the immersion at a controlled rate once the platform is in its final location.

Abstract: Manufacturing, driving and injection method of underwater piles that serve as a foundation for any structure or platform in which one starts with a pillar or pipe (4) to which, during manufacturing, a pile (5) has been inserted in its interior. The methods solve all the possible cases, independently of whether the ground has little resistance or that the load is very great since there are several solutions that the system may adopt to solve all the problems, which are: pile driving on the ground, central injection and by bulb, peripheral injection and radial injection. In addition it includes load tests and an embedding system of the pillar in the slab or structure that is going to support it.

Abstract: Plant for the automated manufacture of truss structures and the process, which includes a zone for positioning the tubes (A) according to the required geometry, a manufacturing zone made up of a zone for joining the heads of the tubes (8) and a zone for shaping and welding the transverse tubes (9), a collection station for the structures (10), a zone for the inspection and painting of the structures (12), a loading and shipping zone and an assembly zone, these latter two are situated in the exterior of the manufacturing plant. This plant enables the manufacture of truss structures of any required size and geometry, avoiding all manual manipulations, increasing quality and reducing costs.

Abstract: Measurement platform for installing in water, very light and easy to transport, which comprises a foundation of improved suction anchor type constituting the platform base. It is driven into the seabed by the pressure difference between outside and inside, and by reversing the pressure gradient it can be extracted for reutilization. The measurement platform also has a series of telescopically connected tubes, a house located on these tubes containing the devices, a vertical shaft wind turbine for powering the assembly, a device for transmitting data (wi-max or equivalent) to the on-land station, a Doppler laser anemometer, security cameras and the terminal of a Doppler current meter. All data recorded by the devices as well as pictures from security cameras will be continuously sent to the on-land station. Thus the security of the facility is increased, and possible sabotages are forecasted.

Abstract: Device and method for installing the third blade (2) of a wind turbine (5), said wind turbine being placed on a platform (4) located on a water surface, so that the device is moved on the platform and along with it towards the final location. The device is moved, through tracks (3), on the platform surface until facing the third blade (2) with its corresponding hole of wind turbine. The blade, vertically held by jaws and legs (1), is lifted, fitted and screwed.

Abstract: System for transferring large loads and method for operating thereof completely versatile and suitable for any load, regardless its weight and size. The system comprises several rolling paths and several trolleys supporting loads. The trolleys have a roll or skid system through which these move forward along rolling paths, a mean for lifting the load to a small distance from the floor using hydraulic cylinders, and a system for avoiding the overturning, of the pinion-rack type, which also serves for guiding and dragging the trolley.

Abstract: Equipment and procedure for the automated manufacture of tubular structures of any size and of polygonal geometry of any number of sides, the said equipment containing a central axis (1) in the form of a tube in which a series of perforations have been made to which are screwed a series of telescopic pistons with suction pad (2) which are those which take the panel and a series of pistons with cooled bronze piece for welding (3), a fixed support (4) and a movable support (6) of the central axis (1), three overhead travelling cranes (7) with drills (8) which make any perforations necessary, automated welding tools (1) which weld the panels of the structure and which can be moved on tracks (12) and a container (9) for the panels (10).
