Embodiment Construction

[0040] Figure 1A and Figure 1B A first embodiment of the annular float 1 of the invention is shown. The floating body 1 has a square shape and is provided with a central moon pool 2 which is also square shaped. The floating body 1 is also provided with a wind turbine 3 located off-centre on the floating body 1 . Although wind turbine 3 is shown as a turbine with a horizontal axis rotor, other types of wind turbines are contemplated, either horizontal or vertical, with one or more rotors, with or without a transmission between the rotor and the generator. Variable speed, or wind turbines with any number of blades. It is also possible to mount several wind turbines on the same buoy. Furthermore, instead, such buoys can also be used to support other types of equipment, for example for the utilization of ocean energy (such as energy from waves, from swells, from tides or from currents, thermal energy from the sea, osmotic energy, or any other type of energy) other types of d...

Abstract

The present invention relates to the field of floating bodies, in particular to an annular floating body (1) comprising a central moon pool (2), configured so that, in water, when the period of the swell and the floating body (1) move in a heave motion When the natural periods of are substantially equal, the vertical force exerted on the floating body (1) by the large amount of water in the central moon pool (2) oscillating in antiphase with respect to the swell at least partially compensates for the force exerted on the floating body by the swell (1) The vertical agitation force on. The invention also relates to a method of at least partially canceling the heave motion of a floating body (1) with its natural period.

Description

technical field [0001] The present invention relates to a floating body and to a method of at least partially eliminating the heave motion of such a floating body. Background technique [0002] The buoyant body is subjected to swell oscillations in all directions. "Heave" is such an oscillatory motion in the vertical direction caused by a swell. Like other oscillatory motions of buoyant bodies, heave has various disadvantages. In addition to the obvious discomfort experienced on decks where the buoy is subjected to such heave, this movement causes high accelerations on the platform that adversely affect the supporting structure, especially when the period of the swell is close to the natural period of the buoy's heave Time. [0003] The natural period T of the heave of the floating body 升沉 It can be expressed by the following equation: [0004] [0005] Here T 升沉 Represents the natural period of heave, M represents the mass (displacement) of the floating body, ρ rep...
