Any mechanism (not shown) may be used to adjust the position of the hydrodynamic control system.
In some embodiments the WEC 100 may also include a hydrodynamic control system 116 (HCS). Cuanto dura un dolor muscular . Providing a WEC comprising a buoyant nacelle, a first spar, a second spar, a first float, and a second float 1602 with various embodiments may include providing any WEC designed in accordance with the concepts and embodiments described above with reference to Figs. Other structural elements of a WEC 100 in accordance with the present disclosure may include a first spar 104 and a second spar 106. A spar (e.g., 104, 106), as that term is used herein, comprises a hollow or solid elongate element. The use of different mooring line 18 PCT/U S2013/062579 WO 2014/052953 materials and different buoyancies of the mooring buoy may allow the designer to select a preferred load-displacement behavior and maximum load capabilities of the mooring leg.
In various embodiments, one or more stators 206 may be fixedly or rotatably attached to an outer nacelle 102 and/or module 118, 120 via a stator interface structure 218. The rotor interface structure 216 and stator interface structure 218 may, in some embodiments be designed to control an air gap between rotors 204 and stators 206. Such interface structures 216, 218 may include, for example, retention slots, weld joints, braze joints, interference flanges, 12 PCT/US2013/062579 WO 2014/052953 bolted or riveted flanges, mechanical rails, magnetic rails, or any other suitable gap control structure. In some embodiments, one or more rotors 204 may be integrated with a direct-drive shaft/hub 202, 203. In other embodiments, and as shown in Figs. In various embodiments having a single PTO, the first float 108 may connect to the rotors 204, and the second float may connect to the stators 206, which may be rotatable stators. The radial distance of the second float 110 from the nacelle 102 is nominally greater than that distance for the first float 108. This distance is tunable for different site locations or wave climates.

In various embodiments, the optimized shape of the second float 110 is similar in outer contour to that of the first float 108. Dolor de la rodilla derecha . In some such embodiments, this similarity allows for both the first float 108 and second float 110 to be made from the same mold and manufacturing process, thereby eliminating the need for multiple sets of manufacturing equipment and further reducing manufacturing costs. For example, in some embodiments the WEC 100 may need to be towed to or from its operational location for deployment or recovery in an orientation different from its nominal operating position.

The ultimate aim of a wave energy conversion device (WEC) is to convert one form of energy into another; in this case, in a chain including hydrodynamic conversion to mechanical torque and ultimately to electrical or other readily transportable forms. Spar access hatches 128 may provide access to the interior of a spar 104, 106. In some embodiments, boarding areas, (e.g., service platforms and/or docking fixtures) may be affixed to the exterior of one or more spars 104, 106 to provide an easier approach to the spar access hatches 128. Internal spar ladders 406 provide for vertical movement within the spar. In some embodiments, the nacelle 102 may be described as a substantially watertight housing within which may be housed one or more rotary-driven power take offs.
While the present invention has been described with reference to various exemplary embodiments, it is understood that the words which have been used herein, are words of description and illustration, rather than words of limitation. Modularization of any particular WEC 100 component may provide the additional benefits of reduced size during transport and/or simplifying at-sea maintenance, each of which reduces costs and operational downtime. Dolor de espalda baja lado izquierdo y pierna . For the purpose of this specification, and unless otherwise noted, these terms are intended to have an inclusive meaning – i.e. This contributes to a continued operation of the WEC 100 in all wave conditions (including storm waves) by removing excess force that would otherwise be created by excess freeboard. 8A. In various such embodiments, directional controls may be attached to the WEC 100 and mooring to rotate the WEC into the oncoming waves.
To improve the ability to transit the WEC 100 into and out of port, the lower regions of the spars 104, 106 and a HCS 116 may be designed to be de-ballasted or attached with lift bags to raise the low region to the surface. Figs. 2A-B are cross-sectional top-views illustrating interior components of a WEC in accordance with various embodiments of the present invention. Figs. 9A-F are side views illustrating an overtopped float correction in accordance with various embodiments of the present invention. In accordance with some embodiments, Fig. Such mechanisms may, in some embodiments, be motorized drives. Numerical analysis confirms that a forward connection improves such a system’s ability to passively orient into the oncoming wave. Shown at time T1 602, 702, the WEC 100 has moved in surge such that the spars 104, 106 and nacelle 102 are to the right (or aft) of center 601 and pitched clockwise.
