Conceptos para controlar el movimiento de plataformas y turbinas eólicas flotantes


Oferta Tecnológica
Una empresa escocesa ofrece conceptos patentados para controlar el movimiento de plataformas y turbinas eólicas flotantes. Para estabilizar y controlar el movimiento, se utilizan sensores que ajustan las turbulencias, aumentando la vida útil de las estructuras en zonas de aguas profundas en las que los sistemas tradicionales no son viables. La empresa, que necesita invertir en I+D para continuar con el desarrollo de los conceptos, busca socios en el sector de energía eólica offshore con el fin de establecer acuerdos de licencia, adquisición y desarrollo.


Concepts for controlling the motion of floating wind turbines and platforms
A Scottish technology initiative offers patented concepts to control the motion of off shore wind turbines and floating foundations. To stabilise and control motion, sensors are employed to adjust turbulence, potentially improving the survivability of structures in deepwater locations where traditional seabed mounted systems are not feasible.

These concepts require R&D investment to progress. Parties interested in offshore wind are sought to license/acquire/develop them further.
Early stage scoping work has been carried out by a prestigious (public sector) Scottish technology initiative, resulting in a portfolio of granted patents in both Europe and the US, which are now available for license or assignation.

Two of the patents are concerned with floating wind turbine platforms and specifically the manipulation of one or more water columns in order to stabilise the platform. Motion sensors are employed to adjust oscillating water columns in order to arrest the undesirable motion of the platform, thereby stabilising them.

A further patent describes a floating wind turbine platform and a system which controls the yaw angle of the wind turbine rotor blade relative to the position of the supporting platform. Sensors can be employed to communicate with a controller and adjust an associated actuator to adjust the rotor position to compensate for detected yaw motion.

This patent portfolio is therefore of benefit in potentially accessing deepwater sites which are currently not feasible for offshore wind farms, and is of most interest to developers, operators, installers and maintenance companies which are already active in the offshore wind industry.

Technical cooperation is sought from these types of contacts for licensing/acquisition and further development to assess the technical feasibility and performance of this conceptual system.
Advantages and Innovations:
Provides a potential solution to the stabilisation of floating offshore wind turbine platforms which does not require anchoring to the sea bed.

The compelling advantage of floating offshore wind is access to huge wind resource over deep waters which is not presently accessible due to depth constraints of traditional seabed mounted systems.

A further advantage of positioning in deepwater is that wind farms can be placed in positions far from shore where they are not visible negating any negative 'visual pollution' arguments.

Finally, there are also several manufacturing advantages to floating platforms, such as using less material in construction and reducing the need for speciality marine engineering expertise. One major cost driver for conventional offshore wind are the heavy lift vessels required to erect the turbine. Very expensive special purpose ships are required to transport the parts on site and perform the assembly.

Floating turbine platforms, however, are designed to be assembled in port and towed into position using simple barges or tugboats. This can result in major cost savings and greatly increased flexibility in construction.

Granted patents offer monopoly rights and freedom to operate in respect of these inventions in both Europe and the US.

Partner sought

Type and Role of Partner Sought:
Parties with an interest in acquiring or licensing the granted patents associated with these inventions are sought.

Partner organisations from either an academic or industrial background are welcome. However interested parties should be aware they will be required to develop this technology from an early conceptual stage. Testing, validating, and building on the protected inventions from the ground up.

Its envisaged partners will likely already be working in the offshore wind area and potentially in floating platforms although credible enquiries from parties interested in moving into this emerging area are also welcome.
