Definitions

  • the present invention relates to a floating wind turbine.
  • a floating wind turbine is a wind turbine mounted on a floating structure that allows the wind turbine to generate electricity in water depths where bottom-mounted towers are not feasible.
  • a floating wind turbine its dynamic behaviour, performance and costs of manufacture, operation and maintenance are important factors to consider.
  • Offshore wind turbines may be installed on floating structures when the water depth may be too large to accommodate a fixed structure.
  • a floating structure may be used to support the wind turbine.
  • Such a floating structure may be a semi-submersible structure or a spar structure or a column structure or any other floating structure.
  • the floating structure provides enough buoyancy to support the weight of the wind turbine, and sufficient stability to keep pitch, roll and heave motions within acceptable limits. Pitch and roll motions of the floating wind turbine may be effectively countered by increasing the dimensions of the floating structure. However, although greater dimensions results in a greater stability of the floating structure, they also result in higher manufacturing and/or installation and/or operating costs.
  • a first aspect of the present invention is directed to a wind turbine carrying semi-submersible comprising three buoyant stabilizing columns and a mooring system, said mooring system including at least one catenary mooring line that is connected to the semi-submersible at a point above an operational waterline thereof.
  • the operational waterline may also be referred to as the sea level.
  • the presently disclosed floating wind turbine includes a floating structure in the form of a semi-submersible having at least three stabilizing columns.
  • a semi-submersible combines a relatively shallow draft with overall good stability in both operational and transit conditions. This renders the semi-submersible more economical to commission and decommission than alternative structures, such as for instance deep-draft spars, or in themselves low-stability tension-leg platforms.
  • the semi-submersible can be moored by means of one or more structurally simple and therefore cost-effective catenary mooring lines, which may be ballasted to provide additional tension and increase the floating structure's resistance to pitch and roll.
  • a particularly advantageous feature of the presently disclosed floating wind turbine is that the catenary mooring lines are connected to the semi-submersible at a point above an operational water line thereof, instead of below the operational waterline as in prior art semi-submersible floating wind turbine structures.
  • Such a high connection of the mooring lines to the semi- submersible floating structure elevates the centre of gravity of the assembly, comprising the floating structure and the wind turbine positioned on it, and thus may reduce its stability. Contrary to what would have been expected, the overall effect on the stability is found to be surprisingly favourable.
  • connection of the mooring lines to the semi-submersible reduces the mathematical arm between the point of application of the horizontal wind thrust force on the wind turbine and the points of application of the horizontal components of the restoring forces exerted by the mooring system, which may decrease the trimming moment on the assembly that tends to overturn it.
  • Providing a connection of the mooring lines at or near deck level is contrary to the conventional way of connecting the mooring lines to a semi- submersible or a floating structure, i.e. at an underside of the submerged part of the structure.
  • the horizontal wind load may be approximately 1 MegaNewton (MN) at 90 m above sea level.
  • MN MegaNewton
  • the semi-submersible wind turbine carrying structure may be dimensioned smaller, and may thus be manufactured and/or installed more cost effective and/or may be lighter and/or may be more easy and/or more cost effective in maintenance.
  • Another aspect of the present invention is directed to a method of mooring a wind turbine carrying semi-submersible.
  • the method includes providing a wind turbine carrying semi-submersible according to the first aspect of the present invention, and mooring the semi- submersible at an offshore location by means of the at least one catenary mooring line.
  • the term 'semi-submersible' as used in this text may be construed to refer to a type of specialized marine vessel - often used in the offshore industry as a basis for, inter aha, drilling, production, hotel services, crane operations, and wind turbines - having a waterplane area, i.e. the horizontal cross- sectional area of the vessel at the operational water line/water surface, that is smaller than the cross-sectional area of the vessel below the operational water line.
  • 'catenary mooring line' may be construed to refer to a mooring line, typically in the form of a cable, chain or the like, that is configured to be supported only at its ends, such that the line, in between those ends, is freely suspended and describes a catenary.
  • a 'catenary' is the curve that a hanging cable assumes under the influence of its own weight, when supported only at its ends.
  • the catenary is defined by a hyperbolic cosine.
  • the term 'catenary mooring line' may be construed to include a (ballasted) catenary mooring line that, at one or more positions along its length, has been provided with for instance steel or concrete clump weights to obtain specific
  • the clump weights may in particular serve to reduce tension spikes in the mooring line, and to ensure that it pulls in a generally horizontal direction on an anchor attached thereto.
  • a 'catenary mooring line' should be distinguished from a taut mooring line that is configured to work under large pre-tension.

  • Fig. 2 schematically illustrates a side view of the wind turbine carrying semi-submersible of Fig. 1;
  • Fig. 3 schematically illustrates a top view of the wind turbine carrying semi-submersible of Figs. 1 and 2. Detailed description

  • the tower 36 may support a nacelle that accommodates a generator assembly, and that is rotatably connected to a rotor assembly.
  • the tower 36 may have for example a height of approximately 50 - 100 m.
  • the shaft of the nacelle may for example be positioned at a height of approximately 90 m above sea level.
  • the rotor assembly may include a plurality of elongate rotor blades, typically having a length in the range of 30- 80 meters, which may be connected to a central hub by means of a pitch adjustment mechanism.
  • the generator assembly may typically include a drive shaft that couples the rotor hub to a gear box, which in turn may be operably connected to an electrical generator. Accordingly, the rotor assembly may be operably connected to the generator assembly to enable the conversion of wind- induced rotational motion of the rotor blades into electrical energy.
  • the wind turbine may be of a different design, and for instance include a vertical-axis wind turbine. It will be clear that the physical
  • the dimensions and mass of a wind turbine may influence the dynamic behaviour of the semi-submersible 10 carrying it.

  • a diameter of a column 12 with a circular or a square cross-section may be approximately 8 m.
  • the stabilizing columns 12 may be interconnected by and/or support a deck structure 16 that provides for a main deck 18.
  • the semi-submersible 10 may be configured such that an operational waterline extends well below the deck structure 16, and the highest expected waves will not reach the bottom of the deck box.
  • a main deck of the deck structure 16 may be approximately 18 m above the sea level.
  • the wind turbine 30 may be connected to the deck structure 16 and extend upwards from the main deck 18. Seen in a top view, the wind turbine 30 may be preferably be symmetrically disposed at a geometric centre of the three stabilizing columns, as in the embodiment of Fig. 1.
  • the wind turbine 30 may be asymmetrically disposed on top of one of the stabilizing columns 12.

  • the lower end of one or more of the stabilizing columns 12 may be provided with a transversely extending damper box 14 that provides for hydrodynamic added mass and damping, and so for improved heave, pitch and roll motions.
  • the semi-submersible 10 may also include a mooring system 50 for securing the semi-submersible at a desired offshore location to the sea bottom.
  • the mooring system 50 may be able to resist environmental loads while allowing for first order wave motions.
  • the mooring system 50 may include at least one catenary mooring line 54, which may be made of any suitable material, such as, for instance, metal chain, wire rope, artificial fibers (e.g. polyester) or combinations thereof. Depending on the water depth, the mooring line may have an other configuration than catenary, e.g. straight.
  • each mooring line 54 may be connected to an anchor, e.g. a drag embedment anchor, that is to be placed on the seabed. Other anchoring structures may be possible, There may be anchors that embed into the seabed.
  • the respective mooring line 54 may be connected to the semi- submersible 10 at a point above an operational waterline70 thereof.
  • the at least one mooring line 54 may be connected to the deck structure 16, preferably at main deck level 18. The connection of the mooring line 54 may be for example some 18 m above waterline.
  • wind may exert a thrust on the wind turbine at a vertical level high above the operational waterline 70. This thrust may cause horizontal downwind displacement of the semi-submersible 10, and

  • the distance between the points of application of the horizontal wind thrust force on the wind turbine 30 and the points of application of the horizontal components of the restoring forces exerted by the mooring system 50 is reduced. This, in turn, reduces the effective moment on the semi-submersible 10 that tends to overturn it.

  • the number of mooring lines 54 of the mooring system 50 may vary for different embodiments, and typically be between three and twelve.
  • the mooring system 50 may include at least as many catenary mooring lines 54 as there are stabilizing columns 12. This allows each stabilizing column 12 of the semi-submersible 10 to be associated with at least one mooring line 54, which may then be connected to the semi-submersible 10 at that respective, associated stabilizing column 12 to obtain a symmetric mooring configuration.
  • the semi-submersible 10 may include one or more mooring line guidance chutes or bending shoes 52 via which a respective catenary mooring line 54 may be angled down and outward from the deck structure 16 to the sea bed.
