Offshore wind turbine installation system and method

Номер: US20120000071A1

Автор: Peter Graham Harris

Принадлежит: Technip France SAS

The disclosure provides a method and system for installing components for an offshore wind turbine assembly independent of cranes and derricks. The components are stored in an offshore structure, such as a Spar. After transporting the offshore structure horizontally to a site, the structure can be uprighted to a vertical orientation. A variable ballast component coupled to a tower of the wind turbine assembly can reciprocally retract the tower into the offshore structure to lower the tower, and extend the tower away from the offshore structure to raise the tower until the full quantity of blades are assembled to a turbine coupled to the tower. When the blades are stored in a peripheral fashion around the tower, the method and system provides for automatic rotational indexing of the tower as the tower and turbine retract and extend, so the turbine is progressively aligned with each blade to be installed.

Hybrid laser arc welding process and apparatus

Номер: US20120000892A1

Автор: Daniel Anthony Nowak, Paul Stephen Dimascio

Принадлежит: General Electric Co

A welding method and apparatus for welding workpieces together by conducting a laser beam welding process on a joint region that includes a weld seam defined by and between faying surfaces of the workpieces, and then conducting a hybrid laser arc welding process on the joint region. The laser beam welding process entails causing a first laser beam to travel along the joint region, penetrate the weld seam and form a weldment. The hybrid laser arc welding process remelts the weldment by simultaneously causing an electric arc and a second laser beam to overlap and travel along the joint region and form a weld pool in the weldment. On cooling, a weld joint is formed within the joint region and its weld seam.

The present invention is base on aerodynamic flows and turbulences that surround tall building under various wind conditions. When buildings are relatively tall, there is more airflow surrounding their walls than over it. When the wind reach in angle a surface of a building, this wind will generally slide on this face to the end of it. As all the wind that come to that surface will run to the same ending point, there will be an important concentration of wind at this point. On the other hand, the following wall will receive no wind and will be under low pressure. This is a perfect location for wind turbine, and the first object of our invention.

The invention provides wind energy use. One application provides wind energy use for water harvesting from natural humid air. The method is based on changing thermodynamic state parameters of ambient wind air portions passed through a device comprising convergent-divergent and wing-like components. Those components transform the ambient wind portions into fast and cooled outflowing air portions. A decrease in static pressure and temperature triggers condensation of water-vapor into water-aerosols. Another application of the method provides an effective mechanism for harvesting electrical energy from naturally warm air using renewable wind energy, including the wind inertia, internal heat, and potential energy stored in the air mass in the Earth's gravitational field. The electrical energy harvesting mechanism is also applicable to use of natural renewable energy of streaming water.

A wind turbine utilizes a rotor assembly rotating about a substantially horizontal shaft, wherein said rotational motion is converted to a substantially vertical rotational motion through a shaft extending down from the nacelle located near the top of the tower structure to a mechanical room located at a lower altitude relative to the top of the tower. Said lower mechanical room houses some of the large heavy operational components of the turbine such that the turbine is not as top heavy as conventional turbines, and maintenance of the turbine is improved through ease of access to the lower altitude mechanical room.

Vertical axis turbine blade with adjustable form

Номер: US20120163976A1

Автор: João P.S. CATALÃO, Nelson C. BATISTA, Rui Melicio

Принадлежит: Universidade da Beira Interior

The disclosed subject matter provides blades for vertical axis turbines capable of being operated by airflow and/or fluid. The turbine performance is optimized and adjusted with respect to an installation site adapting the turbine to the site and flow needs by modifying the blade's form. The blades can be configured so as to be capable of adjusting the position angle of its ends, leading to an increase in stability, particularly when the turbine reaches high rotational speeds. This configuration also provides the turbine with the ability to self-start more efficiently. The changeable blade ends can give the turbine the ability to absorb the energy of the fluid flow when it reaches the turbine at almost any angle in a vertical or horizontal plane and therebetween.

A blade is rotatably connected to a strut extending from a rotatable shaft. The blade pitch is controllable with a guide pin positioned substantially near the trailing edge of the blade. The guide pin follows a guide track resulting in a blade pitch that may change as the blade rotates through a revolution. Multiple guide tracks may be used to change the blade pitch pattern at a given position as a result of varying operating conditions such as wind velocity. Using guide track pitch control, the drag and lift forces can be optimized for improved starting torque as well as improved lift and reduced drag under high wind velocity conditions.

Energy Generation System Using Underwater Storage of Compressed Air Produced by Wind Machines

Номер: US20130019591A1

Автор: Herbert L. Williams

Принадлежит: Individual

An offshore floating wind farm producing compressed air in varying quantities depending on the wind speed, the compressed air being delivered to a large-volume, thin-walled, underwater storage bladder or tank, the compressed air then being delivered to an electricity-generating power plant to power generators as needed. The system may also include an onshore wind farm that produces compressed air in varying quantities depending on wind speed, the compressed air being delivered directly to the power plant. When compressed air production exceeds the needs of the power plant, the excess compressed air is delivered to the underwater storage tank. When onshore production is inadequate, compressed air is brought from the underwater storage tank to the power plant.

A floating structure has an annular support as an underwater support with a buoyant body. A tower penetrates the annular support centrally and is connected to the annular support at a location underneath the annular support by slantedly outwardly ascending tension spokes and at a location above the annular support by slantedly outwardly descending tension spokes. Anchors on the ocean floor are connected by tension elements with the annular support. The structure is built by the steps of supporting by auxiliary devices the annular support on a floor of a basin that can be flooded; positioning the tower at the center of the annular support in vertical position; attaching the tension spokes at the annular support and at the tower; flooding the basin; towing the structure to its desired final position; and lowering and anchoring the structure in a submerged floating position.
