Definitions

  • the present invention relates generally to floating platform and an energy producing plant comprising such a floating platform.
  • the energy producing plant comprises at one or several energy producing systems, for example wind power generators, attached to the floating platform.
  • This plant is a floating platform comprising a frame work constructed of hollow pipes/ beams connected by nodes surrounding a center node. On the nodes wind generators may be placed. Each pipe/beam is sealed in its respective end and forms separate floating parts adapted to be connected to the nodes. Further, the volumes within each floating part, i.e. beams and nodes, are connected to each other. I.e. nodes and pipes/beams are connected so that the pipes/beams form transport paths between the nodes. The space in these parts can be used as transport paths, workshops, storage rooms, accommodations or provide space for other functions.
  • JP2007160965A another floating platform comprising separate radially arranged floating parts connected to each other in a central point. Tensile forces are created between each floating part by a tension part provided between the floating parts. Using this construction decreases the forces acting on the platform, thus makes it possible to use construction details of a smaller dimension.
  • the large sea based platform may also function as a sea harbor. It is also desirable to be able to directly reach the center node with a ship or other water borne vessels. The transport to and from the plant and its maintenance may then be simplified.

  • An object of the present solution is to create a floating platform which can be mounted far out in the ocean and which may be used as a platform for an energy producing plant comprising one or several energy converting systems, for example a plurality of wind power generators attached to the platform.
  • the floating platform shall be easy to assemble, repair and maintain and may also function as a floating harbor. This floating platform is described in claim 1 .

  • the units may be arranged to move in an essentially horizontal direction towards each other and/or in an essentially vertical direction to position each unit in an essentially equal horizontal position.
  • the propulsion devices may also be used to help positioning the peripheral units in relation to each other and the nodes when the platform is assembled.
  • the propulsion device is a thruster.
  • a thruster is a thoroughly tested system for controlling the position of stern or bow of a spacecraft or watercraft. It may also be used for station keeping of the craft. A thruster may therefore be a suitable propulsion device for the peripheral unit.

  • peripheral connection members are elastic or semi-elastic or at least one of the peripheral connection members is in at least one end attached to the respective peripheral unit via an articulated joint. This, in order to allow the floating peripheral units to move in relation to each other.
  • the peripheral connection member is constructed to allow movement between the adjacent floating peripheral units. When a slight movement is allowed, the forces in the structure and its attachment points are decreased. If a movement is allowed it is also possible to detach the peripheral floating units from each other without creating an increased tension in the structure.
  • the peripheral connection member itself is flexible, for example by using a rope or similar, or the distal ends of the peripheral connection member can be attached articulately to the respective peripheral unit, preferably with a joint arrangement.

  • the peripheral units When using an elongated object the peripheral units may be arranged in a pattern creating a hexagon shape with one center node. This creates a natural optimized balanced structure. However, other shapes are of course also possible.

  • least one of the peripheral connection members is in at least one end detachably connected to the respective adjacent peripheral unit.
  • the invention further relates to an energy producing plant comprising; a floating platform according to the above described, an energy producing system and an anchoring system arranged to anchor the floating platform to the bottom of an ocean.
  • the energy producing system which is used may be at least one of; a wind power generator, wave power generator, sun cell or wind shovels.
  • Each floating peripheral unit of the energy producing plant may also comprise at least one semi-submersible node on which a wind power generator is mounted.
  • the inventive platform as a base for an energy producing plant is particularly of interest since the platform is very well suited for this application, due to the fact that it can operate independent of depth and far out on the open ocean.

  • the anchoring system is attached to the central unit, thus enabling the entire platform to rotate and automatically adjust in line with the wind and/ or water current direction so that the energy producing systems are placed in an optimum position for energy extraction.
  • wind power generators When wind power generators are used they can be placed on the semi-submersible nodes of the platform, thus enabling access to the generator housing through the hollow interior of the nodes and the connection members.

  • the propulsion device may also be a separate propeller or jet engine of any kind. It is also possible to arrange the propulsion device 1 1 in a vertical position or to make the device 1 1 rotatable in relation to the peripheral unit around an essentially vertical or horizontal axis. This makes it possible to control the motion of the peripheral units 2a-2d in a horizontal and vertical direction and also in all directions there between.

  • FIG 5 a second embodiment of the propulsion device 1 1 is shown.
  • the propulsion device 1 1 in this case a vertically arranged thruster, is here directly attached below the node 4, i.e. at its bottom surface.
  • the entire thruster may be rotatable around a vertical rotation axis A1 .
  • the drive unit creating the rotation of the thruster may for example be arranged inside the node 4.

Abstract

L'invention concerne une plate-forme flottante (1) comprenant au moins trois unités périphériques flottantes ou semi-submersibles (2 ; 2a, 2b, 2c, 2d) et une unité centrale flottante ou semi-submersible (3). Chaque unité périphérique (2 ; 2a, 2b, 2c, 2d) est disposée reliée à l'unité centrale (3) par au moins un élément de raccordement (5) disposé dans une direction sensiblement radiale et reliée aux unités périphériques adjacentes (2 ; 2a, 2b, 2c, 2d) par au moins un élément de raccordement périphérique (6). L'invention est caractérisée en ce qu'au moins un dispositif de propulsion (11) est disposé sur chaque unité périphérique submersible (2 ; 2a, 2b, 2c, 2d), l'élément de raccordement périphérique (6) étant un objet allongé de longueur variable construit de façon à créer une force de tension tirant les unités périphériques flottantes (2 ; 2a, 2b, 2c, 2d) les unes vers les autres.
