6 sencillos ejercicios para eliminar el dolor de ciático.. 5. The platform of claim 1, in which the horizontal damping plate is circular and is secured to the bottom of the hull. 3. The platform of claim 1, in which the hull is a cylinder having a substantially constant circular cross section and includes eight upper and eight lower damping plates circumferentially spaced around the cylindrical hull at their respective areas.

Fisioterapia a domicilio a Riviera Canton Ticino.. 2,. The platform of claim 1, in which the upper and lower damping plates are rectangular, the long dimension of the plates extending in a vertical direction. Upper and lower damping plates 40 and 42 act in combination to dampen pitching motion of the platform induced by waves having a wave period ator near the natural period of oscillation of the platform.

Considering the response of a floating body, it can be seen that if the natural period of oscillation of a floating body is at or near the period of the waves of highest energy striking the platform at any given time, that resonance will occur and motions become so violent that the platform will be totally useless.

Typical of the motions imparted to a floating body by oscillatory waves are heaving (vertical motion), pitching (angular motion), and surging (lateral motion). The plates dampen pitching and heaving motions of the platform caused by Waves having a period at or near the natural periods of oscillation of the platform so that resonant motion cannot occur. In accordance with this invention, therefore, damping means are provided on the platform to dampen oscillatory motions of the platform caused by waves at or near its natural period of oscillation so that such resonance cannot occur.

1, this means comprises a plurality of upper and lower vertical damping plates 40 and 42, respectively, that extend in a radial direction from the submerged upper and lower side walls of hull 22. Preferably, the upper edges of upper plates 40 are adjacent the still water line of the hull so that these plates are normally submerged at all times. A plurality of upper and lower vertical damping plates are provided that are spaced around and extend in a radial direction from at least a portion of the submerged upper and lower side walls of the hull. 8. Dolor de espalda calor o frio . The upper end of flow line 54 is similarly connected to hull 22 by tension link 76 to relieve tension on coil 7 In either of the embodiments shown in FIGS.

FIG. 9 is a detail showing a method for constructing the flow line coil of FIGS. As embodied, and as shown in FIG. This invention relates to stable ocean platforms suitable for oil well drilling, petroleum production and storage, communication facilities, satellite observations, and the like. Accordingly, a primary object of this invention is to provide a new and improved floating marine platform that remains sufficiently stable to be habitable and operational under all sea conditions. Thus it can be seen that the invention provides a new and improved stable, floating marine platform that remains habitable and operational under all sea conditions, especially resonance conditions, and a flow line system that remains intact between the platform and underwater well head despite the conditions of the sea. In accordance with the objects, this invention provides a stabilized floating marine platform comprising an elongated, substantially symmetrical hull of draft such that its lower portion is below the zone of significant vertical wave motion, and of a size such that its natural period of oscillation in pitch and heave is greater than the period of the waves of maximum energy to which the platform may be exposed.

The horizontal damping plate dampens heaving or vertical motion of the platform caused by waves oscillating at or near the natural period of oscillation of the platform to prevent the occurrence of resonance conditions. 10, it can be seen that under these conditions, heaving was limited to about of wave height. With reference to this figure, it can be seen, for example, that while the heaving of the platform increased with increasing wave periods, resonant heaving at or near the natural period of the model was prevented by the horizontal damping plates which limited vertical movement to one and one half times wave height. Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Balancing this of course will be the restoring forces derived from the displacement of the body by the motion of the sea from its resting displacement and its mooring system.
