Definitions
- the invention relates to an arrangement for the stabilization of a floating foundation, which is used offshore to carry a wind-turbine.
- Floating foundations for wind-turbines are known from WO 2006 132 539 A1 and from WO 2006 121 337 A1 showing so called “spar-buoy”. These spar-buoy-types are fixed at a predetermined position by the use of one set of mooring cable.
- FIG. 3 shows a typical spar-buoy foundation according to the state of the art.
- a wind-turbine 1 is mounted on a tower 2 , which is supported by a spar-buoy foundation 3 .
- First endings of the mooring cables 5 are attached to the spar-buoy foundation 3 at a certain position 4 , while second endings of the mooring cables are attached to anchors 6 .
- the level of the position 4 is below the waterline WL.
- the overturning moments are performed by waves and wind while the restoring moment is performed by the weight of the foundation, which acts on the lower end of the foundation.
- FIG. 4 shows with reference to FIG. 3 typical operating loads of a normal spar-buoy foundation.
- the whole structure is generally exposed to an arising overturning moment.
- the overturning moment is defined as multiplication from a wind-load 8 , acting on the wind-turbine 1 , and a lever-arm 9 , which length is defined by the distance between a force centre and the mooring cable attachment 4 .
- the overturning moment is additionally defined as multiplication from the wind load 10 , acting on the tower 2 , and a lever-arm 11 , which length is defined by the distance between the wind-load-force-centre and the mooring cable attachment 4 .
- Last the overturning moment is additionally defined as multiplication from a wave and current load 12 multiplied with an arm-lever 13 , which is defined by the distance between this force centre and the mooring cable attachment 4 .
- the restoring moment is the gravity load 14 of the balancing weight 7 multiplied with a lever-arm 15 , which is defined by the distance from the gravity force centre to the mooring cable attachment 4 .
- An object of the present invention is to provide an improved arrangement for the stabilization of a floating foundation to be used offshore.
- the arrangement for stabilization of a foundation is arranged to carry a wind-turbine mounted on a tower.
- the foundation is fixed with a set of mooring cables.
- First endings of the mooring cables are attached to the foundation at a certain position while second endings of the mooring cables are attached to the floor.
- There is a second set of mooring-cables while first endings of the second set of mooring-cables are attached to the foundation near or at its bottom end. Second endings of the second set of mooring-cables are attached to the floor, too.
- the inventive arrangement allows a higher stabilisation of the floating foundation, which is arranged to carry a wind-turbine.
- the inventive arrangement is cheap and is easy to implement even at older locations, which are already at work.
- FIG. 1 shows a spar-buoy foundation according to the invention
- FIG. 2 shows with reference to FIG. 1 operating loads of the inventive spar-buoy foundation
- FIG. 3 shows a typical spar-buoy foundation according to the state of the art.
- FIG. 4 shows with reference to FIG. 3 typical operating loads of a normal spar-buoy foundation.
- FIG. 1 shows a spar-buoy foundation according to the invention.
- a wind-turbine 1 is mounted on a tower 2 , which is supported by a spar-buoy foundation 3 .
- First endings of the mooring cables 5 are attached to the spar-buoy foundation 3 at a certain position 4 , while second endings of the mooring cables are attached to anchors 6 .
- the level of the position 4 is below the waterline WL.
- First endings of the mooring cables 17 are attached to the spar-buoy foundation 3 near or at the bottom end of the foundation 3 .
- Second endings of the mooring cables 17 are attached to the anchors 6 , preferably. It is also possible to use another set of anchors for this mooring-cables 17 .
- the two sets of mooring cables 5 and 17 serve to stabilise the foundation. Therefore the restoring moment will be a combination of a first moment, arising from the weight of the lower end of the foundation, and a second moment, arising from differential forces in the mooring cables 5 and 17 .
- FIG. 2 shows with reference to FIG. 1 typical operating loads of the inventive spar-buoy foundation 3 .
- the whole structure is generally exposed to an arising overturning moment.
- the overturning moment is defined as multiplication from a wind-load 8 , acting on the wind-turbine 1 , and a lever-arm 9 , which length is defined by the distance between a wind-load-force-centre and the mooring cable attachment 4 .
- the overturning moment is additionally defined as multiplication from the wind load 10 , acting on the tower 2 , and a lever-arm 11 , which length is defined by the distance between the wind-load-force-centre and the mooring cable attachment 4 .
- Last the overturning moment is additionally defined as multiplication from a wave and current load 12 multiplied with a arm-lever 13 , which is defined by the distance between this force centre and the mooring cable attachment 4 .
- the restoring moment is the horizontal component 18 of a second mooring cable force 19 , multiplied with an arm 20 from the attachment point AT of the second set mooring cables 17 to the attachment point 4 of the first set of mooring cable 5 .
- the mooring arrangement of the spar-buoy foundation the same loading situation will lead to about 3 m displacement of the tower top and about 1.5 degrees maximum inclination. So the inventive arrangement leads to a higher stiffness.
- first set of mooring-cable 5 and/or the second set of mooring cable 17 are fitted with tensioning devices, to allow an adjustment of the relative tautness of the particular set of mooring cable.
