Abstract:
Transport frame and method; the transport frame having a longitudinal, lateral and upright extent, and being configured for receiving a tip portion of a longitudinally extending wind turbine blade, said frame being stackable with identical frames, said frame having a tip saddle assembly comprising a saddle with a support surface shaped to receive a blade tip with its chordwise extent lying approximately horizontal, and a clamping mechanism having a hinged clamping arm configured to be operable between a raised, open position and a lowered, closed position; said clamping arm, when open, allowing a blade tip to be lowered into said saddle with its chordwise extent generally horizontal, and when closed, securely restraining said blade tip against upward movement; said clamping arm extending between a hinge point and a free end; said tip saddle assembly further including a preventer serving to maintain said clamping arm in said closed position over a blade and which preventer has a middle portion extending between a first end and a second end; and wherein said tip saddle assembly further includes a fixing for respective said first and second end of said preventer; said tip saddle assembly being configured such that said preventer exerts a downward force on said clamping arm when a middle portion thereof passes under tension over a portion of said clamping arm between said hinge point and said free end, and wherein said preventer is anchored at said first and said second ends to said tip saddle assembly.
Abstract:
Transport frame pair configured for transporting a wind turbine blade, said frame pair comprising a tip frame and a root frame, each said tip and root frame being stackable with identical frames for blade transport or storage, each one of said tip and root frame comprising four upright frame struts which together define a generally cuboid internal space having a longitudinal extent between two pairs of said upright struts; said tip frame comprising a tip saddle assembly within said generally cuboid internal space, and said root frame comprising a root saddle assembly within said generally cuboid internal space, and wherein said root frame is configured to prohibit a translation movement of said root saddle assembly in a longitudinal direction of a blade supported in a root saddle of said root saddle assembly; and wherein said tip frame allows a translation movement of said tip saddle assembly in a longitudinal direction of a blade supported in a tip saddle of said tip saddle assembly. The longitudinal extent of the root frame may be more than twenty percent greater than the longitudinal extent of the tip frame.
Abstract:
In order to allow for a safe and cost-efficient lifting of components (1) from a service vessel (2) to a location on an off-shore wind turbine generator (3) or lowering of components from a location on an off-shore wind turbine generator to a service vessel a method involving the use of a handshake-tool (10) is provided my means of which the component to be lifted or lowered can easily be transferred from one crane to another.
Abstract:
In order to provide an improved and cost-efficient method for performing an exchange of up-tower main components on an off-shore wind turbine a method is disclosed in during which a non-permanent service platform is temporarily coupled to a wind turbine tower lower section. In addition, a wind turbine structure and a system including such a structure are described, the wind turbine structure and the respective system being designed to allow performing the described method.
Abstract:
Transport frame and method; the transport frame having a longitudinal, lateral and upright extent, and configured for transporting a root end of a longitudinally extending wind turbine blade having a root face with protruding stud-bolts, said frame comprising a root saddle, said frame further comprising a releasable interface clamp configured for fixing a said blade root in said frame, said interface clamp extending from a forward nose through a rear hinge point in said root frame and, said interface clamp comprising a body with a forward abutment surface and a bearing surface rearward of said abutment surface, said body being hingedly movable into or out of engagement with one or more stud bolts protruding from the root face of a blade when positioned in said saddle, said interface clamp having a retracted position with its body away from said blade root face and away from said protruding stud-bolts, said interface clamp having an engagement position in which its said bearing surface extends transverse and adjacent to one or more said stud-bolts such that a tightening force applied to a said bearing surface pushes said abutment surface against said root face.
Abstract:
Transport frame and method; the transport frame having a longitudinal, lateral and upright extent, and being configured for receiving a tip or root portion of a longitudinally extending wind turbine blade, said frame being stackable with similar frames, said frame comprising four upright frame struts which together define a generally cuboid internal space having a longitudinal extent between two pairs of said upright struts; said frame having, within said generally cuboid internal space, a tip or root saddle assembly comprising a saddle with a support surface shaped to receive a respective blade root or tip; said frame furthermore having four top shoulders and four feet, said feet of said frame being conformed to be stackable on corresponding said shoulders of another frame; and wherein said frame, proximate one or more said top or bottom corner thereof, comprises a retractable arm arrangement; wherein said frame further comprises, proximate at least one said top or bottom corner thereof, a claw arrangement; said retractable arm arrangement being configured to fixingly engage a corresponding claw arrangement at an adjacent similar frame in a stacked arrangement of the frames.
Abstract:
A method for storing and/or transporting a plurality of objects (5a, 5b) for one or more wind turbines is presented, the method comprising arranging a first object (5a) to be supported by a plurality of wheels(901), arranging a second object (5a) to be supported by a plurality of wheels(901), rolling the first object into a first location(13a), subsequently raising the first object to a second location (13b) above the first location, and subsequently rolling the second object into the first location, thereby inserting the second object under the first object.
